Wolverine Research Pen 20mg: Complete Product Overview
This Wolverine stack peptide pen is a ready-made solution format. There is no powder to reconstitute and no second vial to combine: both peptides are supplied together, at a stated ratio, in a sealed cartridge inside a multi-use pen body. It is intended for researchers whose study design calls for a combined, pre-dissolved solution of BPC-157 and TB-500. Each pen is labelled with a batch number and expiry date and matched to a batch COA.

What Is in the Wolverine Pen: Composition, Ratio and Format
The Wolverine pen peptide blend combines two synthetic peptides in one solution:
- BPC-157, a 15-amino-acid peptide (pentadecapeptide)
- TB-500, a synthetic peptide related to the naturally occurring protein thymosin beta-4 (Tβ4)
The two are combined at an equal mass ratio of [CONFIRM: 1:1 by mass, 10mg:10mg]. Equal mass is not the same as equal numbers of molecules, which is explained in the equimolar section below. The solvent is [CONFIRM: e.g. bacteriostatic water / sterile water] with [CONFIRM: preservative, if any, e.g. benzyl alcohol or m-cresol]. Because it is a Wolverine stack pre mixed pen, the ratio and concentration are fixed at manufacture.

Who Is This Wolverine Research Pen Made for? A Guide for Laboratory Researchers
This pen is sold to adults buying for in-vitro or laboratory research, such as academic groups, contract research labs and independent researchers studying peptide stability in solution, multi-dose device formulation or the cell biology of tissue repair. It is not sold for personal use or for use in animals outside an approved research setting. If you are looking for something to use on yourself, this is not the right product, and we would point you to a GP or pharmacist instead.
What Is the Wolverine Peptide Stack and Why Is It Studied in Peptide Research?
“Wolverine stack” is an informal market name for a blend of BPC-157 and TB-500. A Wolverine stack peptides pen simply supplies that blend as a pre-filled solution. The two peptides are unrelated: they have different origins, different sizes and, according to the research so far, act through different pathways. That difference is the main reason researchers are interested in studying them side by side.
The Wolverine Stack Explained in Plain English: BPC-157 and TB-500 Together
Think of the stack as two separate research compounds in one container. BPC-157 is a short, 15-amino-acid chain; TB-500 is either a 43-amino-acid protein or a 7-amino-acid fragment of it, depending on the supplier. Neither is an approved medicine. The name comes from the Marvel character known for fast healing, which reflects how the blend is marketed, not any proven effect. A Wolverine peptide stack pen is the same pairing supplied in pen format.
BPC-157 Explained: A Synthetic Peptide Used in Laboratory Studies
BPC stands for “Body Protection Compound”. BPC-157 is a chain of 15 amino acids (sequence GEPPPGKPADDAGLV) based on part of a larger protein that researchers at the University of Zagreb, Croatia, reported finding in human gastric juice in the early 1990s. The peptide used in research is made synthetically. Most published work comes from that same Zagreb group, led by Professor Predrag Sikirić, and nearly all of it is in rats, mice and cell cultures. It is not an approved medicine anywhere in the world [CHECK before publishing].
TB-500 Explained: A Synthetic Peptide Used in Laboratory Studies
TB-500 is a synthetic peptide linked to thymosin beta-4 (Tβ4), a 43-amino-acid protein found naturally in most human and animal cells. Tβ4’s best-known job is binding actin, the protein that forms the cell’s internal scaffold, which affects how cells move and change shape. The name “TB-500” is used in two ways: some suppliers use it for full-length synthetic Tβ4, others for a short fragment of it (Ac-LKKTETQ, amino acids 17–23), the region linked to actin binding. The COA should tell you which one you have. Tβ4 itself has been tested in small human clinical trials (for example as an eye drop) [CHECK]; TB-500 as sold for research has not.
Why Do Researchers Study BPC-157 and TB-500 Together Rather Than Separately?
The interest in the pair is based on the idea that the two may act in different, possibly complementary ways: BPC-157 has mainly been studied for its effects on blood vessel growth and nitric oxide signalling, and Tβ4 for its effects on actin and cell migration. Researchers may want to test whether combining two different pathways changes the result compared with either peptide alone. That is a hypothesis, not an established finding.
How Are the Two Compounds Studied? Research Overview of Their Proposed Mechanisms
In laboratory and animal studies, researchers have proposed several mechanisms. None has been confirmed in humans.
- BPC-157: in rat tendon cell studies it increased cell outgrowth and migration and activated the FAK–paxillin pathway (Chang et al., 2011); other studies report effects on VEGF receptor 2 signalling and new blood vessel formation (angiogenesis), and on the nitric oxide system.
- TB-500 / Tβ4: Tβ4 binds monomeric G-actin, which regulates the cell’s supply of actin for building its scaffold. In cell and animal studies, Tβ4 has been linked to cell migration, angiogenesis and wound closure (Malinda et al., 1999; Goldstein et al., 2005). Data on the short fragment alone are more limited.
Common research methods include cell migration (scratch) assays, tube-formation assays for blood vessel growth, rodent wound and tendon models, and analytical chemistry work on stability and detection.
What Does Current Research Say About the Wolverine Stack, and What Is Still Unknown?
What the research shows: each peptide has a body of preclinical (cell and animal) work behind it. What is still unknown: we are not aware of any published, peer-reviewed controlled study of BPC-157 and TB-500 given together [CHECK: re-run a PubMed search before publishing]. There are no large human clinical trials of BPC-157, only a few small reports, and no human trials of TB-500 as sold. There is also little published data on how stable the two peptides are when stored together in solution over weeks, which matters for any Wolverine stack pen. Whether the two interact, add to each other or interfere with each other has not been tested.
How Does a Research Pen Work? The Pen Format Explained for Researchers
A research pen is a multi-dose device built around a sealed glass cartridge of solution. A dial on the pen sets a volume, and a plunger mechanism pushes that volume out through a separately fitted pen needle. Pen designs come from licensed medicines such as insulin, where the format is regulated under device standards such as ISO 11608 [VERIFY]. A peptide pen Wolverine product borrows the format but is not a licensed medicine or device.
What Is a Peptide Research Pen and How Is It Different from a Vial?
A vial holds the peptide as a freeze-dried (lyophilised) powder under a rubber stopper. The researcher adds a solvent, then draws measured volumes out. A Wolverine peptide pen arrives already in solution, with the volume measured by the pen’s dial rather than by drawing up from a vial. The trade-off is convenience against shelf life: dry powder is generally more stable than solution.
Advantages Researchers Look for in a Pen Format
- No reconstitution step, so fewer handling and calculation errors
- A dial-set volume, which helps keep measured volumes consistent across a study
- Both peptides already combined at a stated ratio and concentration
- A sealed cartridge that limits exposure to air compared with repeatedly punctured vials
- Compact and easy to label and log
Limitations of the Pen Format Every Buyer Should Know About
- Peptides in solution degrade faster than dry powder, so the in-use period is limited.
- The ratio and concentration are fixed; you cannot adjust them or run single-peptide controls from the same pen.
- The pen needs refrigeration from the start, so it is less forgiving during transport.
- Dial increments and accuracy depend on the pen model [CONFIRM: pen increment and accuracy spec].
- Little published data exists on the stability of BPC-157 and TB-500 together in a preserved solution [CHECK].
- Pen needles are sharps, which adds handling and disposal requirements.
Pen Needles and Accessories: What to Check Before You Order
Needles for Wolverine pens are [CONFIRM: not included / included]. If your protocol needs them, check:
- Compatibility: the needle must match the pen’s fitting. Our pen takes [CONFIRM: needle standard, e.g. ISO 11608-2 compatible screw-on pen needles].
- Sterility: each needle should be individually sealed, sterile and in date.
- Single use: pen needles are designed to be used once and then discarded.
- Sharps disposal: you will need a sharps container that meets the relevant standard (see the disposal section below).
We do not provide instructions on administering this product. Pen needle information is for laboratory handling and waste planning only.
Wolverine Research Pen vs Vial vs Nasal Spray: Which Format Should You Choose?
| Research pen | Lyophilised vial | Nasal spray | Two separate vials | |
|---|---|---|---|---|
| Form | Solution in cartridge | Dry powder | Solution in bottle | Dry powder ×2 |
| Reconstitution | None | Yes | None | Yes, twice |
| How volume is set | Pen dial | Drawn from vial | Metered pump | Drawn from vials |
| Ratio | Fixed | Fixed (if blended) | Fixed | Researcher sets it |
| Storage | 2–8°C [CONFIRM] | Cool, dry; freezer long-term | 2–8°C | Cool, dry; freezer long-term |
| Sharps | Pen needles | Syringes | None | Syringes |
The Wolverine stack pen suits researchers who want a ready-made solution with a dial-set volume. The vial suits longer storage and flexible concentrations, and the spray suits intranasal formulation research.
Research Pen vs Lyophilised Vial: Key Differences in Handling and Storage
The pen is ready to use and needs refrigeration from the start. A lyophilised vial must be reconstituted with a suitable solvent, such as bacteriostatic water, but the unopened powder keeps longer and is less sensitive to short temperature changes. Once a vial is reconstituted, it also needs refrigerating and has a limited in-use period.
Research Pen vs Nasal Spray: What Is the Difference in Format?
Both are pre-dissolved solutions of the same two peptides. The [LINK: Wolverine nasal spray] uses a metered pump that delivers a fixed volume per actuation and is designed for intranasal formulation research. The pen uses a cartridge, a dial and a separate pen needle. Concentrations differ between the two products [CONFIRM: pen and spray concentrations], so they are not interchangeable in a protocol.
Pre-Mixed Pen vs a Powder You Reconstitute Yourself: Stability and Convenience
A Wolverine stack pre mixed pen is the most convenient option: the solution is made, sealed and tested before it reaches you. Powder you reconstitute yourself is more stable before use, and you control the solvent, concentration and timing. Peptides in water slowly break down through hydrolysis and oxidation, so a pre-mixed product depends on cold storage and, often, a preservative to stay usable.
Pre-Blended Pen vs Two Separate Peptides: What Researchers Should Know
A pre-blended pen saves time and fixes the ratio. Two separate vials of BPC-157 and TB-500 let you choose any ratio, including a true equimolar one, run single-peptide control groups, and check each peptide’s COA on its own. For studies that compare the blend with each peptide alone, separate vials are usually the better choice.
Which Format Is Easier to Store, Transport and Keep Stable?
Unopened lyophilised vials are the easiest to store and transport, because dry peptides tolerate short periods at room temperature well. Wolverine stack pens and nasal sprays contain solutions and should be kept cold and used within their in-use period. Our pens ship in [ADD: packaging, e.g. insulated pouch with ice pack].
Is the Wolverine Blend a 1:1 Mix? Equal Mass vs Equimolar Explained
The Wolverine stack peptide pen is 1:1 by mass [CONFIRM]: the same number of milligrams of each peptide. It is not 1:1 by number of molecules, because the two peptides have very different molecular weights.
What Does Equimolar Mean for a Peptide Blend?
“Equimolar” means equal numbers of molecules of each compound. Chemists count molecules in moles; one mole of any substance contains the same number of molecules (about 6.022 × 1023). To find how many moles you have, divide the mass by the molecular weight. An equimolar blend would contain the same number of micromoles (µmol) of BPC-157 as of TB-500.
Why Equal Mass Does Not Mean Equal Molar Amounts
BPC-157 weighs about 1,419.5 g/mol [VERIFY]. TB-500 weighs about 4,963 g/mol if it is full-length Tβ4, or about 889 g/mol if it is the Ac-LKKTETQ fragment [VERIFY]. So 10mg of each gives very different molecule counts:
| 10mg of… | Approx. molecular weight | Approx. amount | Molar ratio BPC-157 : TB-500 |
|---|---|---|---|
| BPC-157 | 1,419.5 g/mol | 7.0 µmol | – |
| TB-500 as full-length Tβ4 | 4,963 g/mol | 2.0 µmol | about 3.5 : 1 |
| TB-500 as Ac-LKKTETQ fragment | 889 g/mol | 11.2 µmol | about 1 : 1.6 |
[VERIFY: all figures in this table are calculated from free-base molecular weights and assume 100% peptide content. Real values are lower because peptides are usually supplied as salts (e.g. acetate) with some water; the COA’s net peptide content figure gives the true amount.]
In other words, a 1:1-by-mass blend is only roughly equimolar by coincidence, and only if you know which form of TB-500 it contains. Our pen uses [CONFIRM: TB-500 form], giving an approximate molar ratio of [CONFIRM from table].
How to Check the Exact Ratio on the COA
- Check the COA lists both peptides, with a separate HPLC result for each.
- Look at the mass spectrometry result for TB-500: an observed mass near 4,963 Da means full-length Tβ4, near 889 Da means the fragment [VERIFY].
- Look for the stated amount (mg) of each peptide and, if given, the net peptide content.
- Divide each amount by its molecular weight to get µmol, then compare the two.
If a supplier calls a pen “equimolar” but cannot show these numbers, treat the claim with caution.
Wolverine vs Super Wolverine vs GLOW vs KLOW: What Is the Difference Between These Stacks?
“Wolverine”, “Super Wolverine”, “GLOW” and “KLOW” are informal names the research peptide market uses for multi-peptide blends. They are not scientific or regulated terms, so the exact contents and amounts vary between suppliers. Always check the label and COA.
Wolverine Stack: BPC-157 and TB-500
The Wolverine stack is the simplest: two peptides, BPC-157 and TB-500. Our Wolverine stack pen contains [CONFIRM: 10mg + 10mg] in a pre-filled pen.
Super Wolverine Stack: How Adding KPV Changes the Blend
A Super Wolverine blend is commonly sold as BPC-157 and TB-500 plus KPV. KPV is a tripeptide (lysine-proline-valine) that matches the last three amino acids of alpha-melanocyte-stimulating hormone (α-MSH) and is studied mainly in inflammation research, including cell and rodent models of gut inflammation. Adding it introduces a third compound with a different research focus, and a third variable to control for. Typical amounts are [ADD: your Super Wolverine composition, if sold].
GLOW and KLOW Stacks: How They Differ from the Wolverine Stack
A GLOW blend usually contains BPC-157 and TB-500 plus GHK-Cu, a copper complex of the tripeptide glycyl-L-histidyl-L-lysine, first described in human plasma by Loren Pickart in 1973 and mostly studied in skin and collagen research. A KLOW blend usually contains the three GLOW peptides plus KPV. Typical amounts are [ADD: your GLOW and KLOW compositions, if sold].
Which Stack Do Researchers Choose and Why?
The choice depends on the research question. Fewer components make results easier to interpret, which is why some researchers prefer the two-part Wolverine pen or single peptides for studies on BPC-157 and TB-500 alone. Super Wolverine, GLOW and KLOW add compounds studied in other areas, so they suit study designs that specifically need those compounds. [LINK: Super Wolverine, GLOW and KLOW product pages, if sold]

Batch Number, Manufacture Date and Expiry Information
Every pen is printed with a batch (lot) number, a manufacture date and an expiry date. The batch number links the pen to its COA. Current batch: [ADD: batch number, manufacture date, expiry date, or “see label”].
Download the Data Sheet Before You Order
You can download the Wolverine stack pen data sheet and the current batch COA [ADD: link / button] before buying. We recommend checking that the batch number on the COA matches the batch in stock.
Purity, HPLC Testing and Certificates of Analysis (COA) Explained
Each batch of our Wolverine peptide pen is tested by [ADD: name of independent testing laboratory and its accreditation, e.g. ISO/IEC 17025], which issues a signed COA for that batch.
How Purity Is Reported for a BPC-157 + TB-500 Blend
For a blend, purity should be reported for each peptide separately. HPLC separates the two peptides and any impurities into separate peaks; each peptide’s purity is its main peak area as a percentage of the related peaks. A single “blend purity” figure with no breakdown tells you much less. Our current batch: BPC-157 [ADD: %], TB-500 [ADD: %].
What HPLC and Mass Spectrometry Results Tell You About a Peptide Blend
- HPLC (high-performance liquid chromatography) shows how pure each peptide is and whether there are impurities such as shortened or damaged peptide chains.
- Mass spectrometry (MS) confirms identity by measuring each molecule’s mass. For this blend, the COA should show a mass close to the expected value for each peptide, and for TB-500 it tells you whether it is the full protein or the fragment.
HPLC alone cannot confirm identity, and MS alone cannot measure purity, so a good COA includes both. For a solution product, a sterility or endotoxin test result is also useful if the supplier provides one [CONFIRM if tested].
How to Read the COA for the Wolverine Research Pen Line by Line
- Product name and strength: should say BPC-157 + TB-500, 20mg, and the amount of each.
- Batch number and dates: should match the pen label.
- Appearance: e.g. clear, colourless solution.
- HPLC purity: one result per peptide, with the chromatogram attached.
- MS identity: expected vs observed mass for each peptide.
- Concentration: mg/ml or mg per cartridge, if tested.
- Lab details: testing lab name, accreditation, test date and signature.
How to Check the Batch Number and Product Label Against the COA
Find the batch number on the pen label and compare it, character by character, with the batch number on the COA. The product name, strength and dates should also agree. If anything does not match, do not use the product and contact us at [ADD: support email].
What ISO-Certified Manufacturing Means for Batch Consistency
ISO 9001 is an international standard for quality management. A certified manufacturer must document its processes, train staff, control materials and investigate faults, and is audited regularly. It does not test the product itself, but it makes batch-to-batch consistency far more likely. Our manufacturer is certified to [CONFIRM: standard and certificate number].
How to Spot a Fake or Unverified COA When Buying Peptides Online
- No batch number, or one that does not match the label
- No testing lab named, or a lab you cannot find or contact
- A single purity figure for a two-peptide blend, with no breakdown
- No chromatogram or mass spectrum attached
- The same COA used for every batch, or dates years old
- Purity of exactly 100%, which real HPLC results almost never show
How to Store and Handle the Wolverine Research Pen Correctly
How to Store a Wolverine Research Pen Before and After First Use
Before and after first use, keep the Wolverine stack pen in a refrigerator at 2–8°C, in its outer box, with the cap on and no needle attached. [CONFIRM against label]
Ideal Storage Temperature and Protection from Light
Store at 2–8°C, away from the freezer compartment and the back wall of the fridge, where items can freeze. Do not freeze the pen, because freezing and thawing can damage peptides and the cartridge. Keep it in the box to protect it from light.
How to Keep the Pen Cap, Needle Seat and Cartridge Clean and Sealed
- Keep the cap on whenever the pen is not in use.
- Remove and discard any needle straight after use; a needle left attached can let air in and solution leak out.
- Wipe the needle seat (the rubber septum) with a 70% alcohol swab before fitting a new needle, following your lab’s aseptic procedures.
- Do not refill the cartridge or transfer solution into it.
Why Moisture, Heat and Temperature Changes Can Reduce Peptide Stability
Peptides in water slowly break down through chemical reactions such as hydrolysis, deamidation and oxidation, and heat speeds these up. Repeated warming and cooling can also cause peptides to clump (aggregate), and condensation can carry contamination. Keeping the pen cold, sealed and clean slows these processes.
How Long Does a Wolverine Research Pen Last After Opening?
Once a needle has first pierced the cartridge, use within [CONFIRM: in-use period from your stability data, e.g. 28 days] if kept refrigerated, or by the expiry date, whichever comes first. Note the first-use date on the label.
Does a Wolverine Research Pen Need to Be Kept in the Fridge?
Yes. In solution, keep it at 2–8°C before and after first use. Put it in the fridge as soon as it arrives. [CONFIRM]
Why Is the Pen Shipped Chilled and Insulated?
Because the peptides are already in solution, heat during transit is the biggest risk to quality. Our Wolverine pens are shipped [CONFIRM: chilled, e.g. insulated pouch with gel ice pack; all year or warm months only] to keep them cool until delivery. If a parcel arrives warm or the ice pack has fully melted in hot weather, contact us before using the pen.
Signs of Spoilage, Contamination or Damage to Check for Before Every Use
- Cloudiness, particles or a change in colour in the cartridge
- A cracked cartridge, damaged pen body or broken seal on arrival
- Leaking solution around the needle seat
- A pen that has been frozen or left warm
- A past expiry date or in-use period
If you see any of these, do not use the product.
How to Dispose of Used Pen Needles and Empty Pens Safely
- Used pen needles: put them straight into a rigid, puncture-proof sharps container that meets BS EN ISO 23907 [VERIFY]. Never put needles in general waste or recycling.
- Full sharps containers: close and dispose of them through your laboratory’s clinical or hazardous waste contractor, in line with UK waste rules.
- Empty or expired pens: remove the needle, then dispose of the pen and any remaining solution as chemical waste under your lab’s procedures. Do not empty the solution down the drain.
Safety, Responsible Use and Research-Use-Only Notice
What Does For Laboratory Research Use Only, Not for Human or Veterinary Use Mean?
It means the product is supplied only for in-vitro and laboratory research. It has not been tested or approved as safe for people or animals, it is not made to medicine standards (GMP for medicines), and it must not be injected, swallowed, inhaled or used on the body of a person or animal. The pen format does not change this.
Why We Do Not Provide Dosage, Side-Effect or Medical Advice for BPC-157 and TB-500
Neither peptide is an approved medicine, so there are no established safe doses or side-effect profiles for people. Giving dosing, injection or usage advice would present a research chemical as a medicine, which is unsafe and not lawful. We will not answer questions about dosage, side effects, injection or personal use.
Who Should You Speak to for Health or Medical Questions?
Speak to your GP, a pharmacist or another registered healthcare professional. For urgent advice in the UK, call NHS 111. If you are an athlete, contact UK Anti-Doping (UKAD) before using any supplement or substance.
What UK Buyers Should Know Before Buying Research Peptides Online
- BPC-157 and TB-500 have no UK marketing authorisation from the MHRA and are not licensed medicines. A product sold with medical claims or for human use may be treated as an unlicensed medicine. [LEGAL REVIEW]
- Selling a solution in a needle-based pen may be seen as presenting it for human use. Clear research-use-only labelling and no usage advice are essential. [LEGAL REVIEW]
- Both are on the World Anti-Doping Agency (WADA) Prohibited List: BPC-157 under S0 (non-approved substances) and TB-500 under S2 (as a thymosin beta-4 derivative). Athletes covered by UKAD rules can face sanctions. [VERIFY against the current WADA list]
- In the US, the FDA has placed BPC-157 in a category of substances it says raise significant safety risks for compounding. [VERIFY]
- Buying a Wolverine stack pen in the UK for genuine laboratory research, without medical claims, is how we sell this product.

Where to Buy Wolverine Peptides in the UK: What to Check Before You Order
Whether you are comparing a Wolverine stack peptide pen UK listing or a Wolverine peptide pen UK supplier you have not used before, the same checks apply.
7 Signs of a Reliable Research Peptide Supplier
- A batch-specific COA from a named, independent lab
- Separate purity and identity results for each peptide in a blend
- A clearly stated amount and form of each peptide (including which TB-500)
- Batch number, manufacture date and expiry on every label
- Clear research-use-only positioning, with no health claims, dosing or injection advice
- A UK address, contact details and real customer support
- Clear returns, cold-chain delivery and storage information
Red Flags to Avoid When Buying a Peptide Blend Online
- Claims that the product treats, heals or cures anything
- Dosing charts, “click” guides, “cycles” or before-and-after photos
- No COA, a generic COA or one you can only see after paying
- “Equimolar” claims with no molecular weights or amounts
- Pens shipped with no insulation or cold packs
- Prices far below the rest of the market
- No UK business details or only social media contact
Why Purity, COA, Clear Labelling and Stated Ratios Matter More Than Price
If you do not know exactly what is in the cartridge and in what amounts, your results cannot be interpreted or repeated. A cheaper Wolverine stack pen UK product with low purity, the wrong form of TB-500 or an unstated ratio can cost more in failed work than it saves.
Questions to Ask a Supplier Before You Place Your First Order
- Can I see the COA for the batch I will receive?
- Is TB-500 in this pen full-length thymosin beta-4 or the fragment?
- What is the amount of each peptide, and is it free base or salt?
- What is the cartridge volume, concentration and preservative?
- Which pen needles fit, and are any included?
- How is the pen shipped, and how long does it last after first use?
Wolverine Peptide Price in the UK: What Affects the Cost?
Our 20mg Wolverine stack pen costs [ADD: price]. Here is what drives the price of research pens and blends generally.
Why Purity, Testing, Format and Pack Size Change the Price of a Peptide Blend
- Purity: extra purification steps cost more.
- Testing: independent HPLC and MS for every batch, and for each peptide, adds cost.
- Peptide length: full-length Tβ4 (43 amino acids) is far more expensive to make than a 7-amino-acid fragment.
- Format: a pen includes the cartridge, the pen mechanism, sterile filling and cold-chain packaging, so it usually costs more per mg than a vial.
- Pack size: larger amounts usually cost less per mg.
How to Compare Wolverine Pen Prices Between UK Suppliers Fairly
Compare the price per mg of each peptide, not per pen. Check that both Wolverine pens use the same form of TB-500, the same purity and the same testing, and include needles and chilled delivery in the total cost. A lower price for a fragment version is not comparable with a full-length Tβ4 blend.
