Wolverine Peptide Stack — BPC-157 & TB-500 | 20mg
Wolverine Stack
The Wolverine Stack 20 mg is a dual‑peptide research formulation containing BPC‑157 (10 mg) and TB‑500 (10 mg), supplied in a pre‑configured laboratory delivery format for controlled analytical and in‑vitro experimentation. The preparation is standardised prior to use, allowing researchers to work with a consistent peptide composition and eliminating variability associated with solution preparation. This format supports reproducible handling, uniform exposure conditions, and reliable performance across non‑clinical research workflows. The combined system enables examination of dual‑peptide interactions, signalling behaviour, and structural responses within controlled experimental models. BPC‑157 contributes to peptide‑mediated signalling and cellular response studies, while TB‑500 is commonly used in research involving actin dynamics, cytoskeletal organisation, and structural modelling. Together, they provide a platform for observing coordinated or independent pathway activity within a unified solution matrix.

Wolverine peptide stack: composition, format and quality
Wolverine Stack — searched as Wolverine peptide, the Wolverine stack or simply Wolverine — is the market name for a two-peptide research blend: BPC-157 and TB-500 co-formulated in one vial. The name is a supplier convention rather than a molecule or a claim: what you are buying is defined entirely by the two components and their masses. Ours is supplied pre-mixed as a solution in one sealed vial, 20mg in total, with the reusable pen and needles in the box, and it ships from our UK facility with a batch Certificate of Analysis.
Research use only. The Wolverine Stack is supplied strictly for in-vitro laboratory research. This page describes composition, chemistry, format, quality and handling. It does not describe dosing, administration or use in humans or animals, and makes no therapeutic claims.

What is in the Wolverine peptide vial
| Component | Mass per vial | What it is | Reference values |
|---|---|---|---|
| BPC-157 | 10mg | Synthetic pentadecapeptide (Gly-Glu-Pro-Pro-Pro-Gly-Lys-Pro-Ala-Asp-Asp-Ala-Gly-Leu-Val) | C₆₂H₉₈N₁₆O₂₂ · 1419.5 g/mol · CAS 137525-51-0 |
| TB-500 | 10mg | Synthetic peptide from the actin-binding region of thymosin β4 | C₃₈H₆₈N₁₀O₁₄ · 889.0 g/mol · CAS 885340-08-9 |
20mg in total, split evenly. The two components carry equal mass here, where GLOW and KLOW are dominated by their 50mg of GHK-Cu. The split is the first thing to compare between suppliers, because the name does not fix it: vials sold as a Wolverine or a BPC-157 + TB-500 blend can carry different amounts of each, and 5mg + 5mg is sold under the same descriptions. The Wolverine Stack guide introduces the pairing.
Equal mass is not equimolar
Ten milligrams of one peptide and ten of another are not the same number of molecules, because the molecules do not weigh the same. BPC-157 is 1,419.5 g/mol and the TB-500 fragment is 889.0 g/mol, so an even mass split gives roughly 7.0 µmol of BPC-157 against 11.2 µmol of TB-500 — a molar ratio near 1 : 1.6, not 1 : 1. Any comparison expressed in molar rather than milligram terms has to account for that.
It matters most when comparing suppliers, because the arithmetic depends on which TB-500 the other vial contains. Built from the full 43-residue thymosin beta-4 protein — about 4,960 g/mol, five and a half times the fragment's mass — the same even split runs the other way: about 7.0 µmol of BPC-157 to 2.0 µmol of the protein, a ratio near 3.5 : 1. Two vials that both read "10mg + 10mg" can differ several-fold in molar composition on nothing more than which molecule the second number names, which is why this page prints formulas and masses rather than a size name.
Wolverine, GLOW and KLOW
The three blends are a ladder, and Wolverine is the base of it.
- Wolverine — BPC-157 (10mg) and TB-500 (10mg). Two peptides.
- GLOW — the same two plus GHK-Cu (50mg). Three peptides, 70mg.
- KLOW — GLOW plus KPV (10mg). Four peptides, 80mg.
Each step adds one pathway family: GLOW adds copper-dependent signalling through the copper tripeptide, KLOW a melanocortin-linked probe through KPV. Wolverine is the narrowest of the three and the only one with no metal chemistry in the vial, so it is also the only one whose solution is not blue. The wider sets are not better ones: the choice turns on the pathways a study touches, not the total mass.
Pre-mixed Wolverine vs lyophilised
Most UK suppliers sell this pairing as a co-lyophilised powder reconstituted with bacteriostatic water before use, and most list it under the plain compound names, not as a Wolverine Stack. Ours is supplied already in solution: that removes the reconstitution step and the pipetting error with it, fixes the composition per batch, and makes the vial cold-chain: chilled with frozen gel packs in a sealed foil pouch, into a 2–8 °C refrigerator on arrival, with a stated in-use window, not a shelf life. Reconstitution guidance is absent from this page because there is nothing to reconstitute.
What comes in the box
The sealed pre-mixed vial ships with the reusable pen and needles. The pen is a reusable volumetric dispensing device; the pen guide covers its mechanics. A bare vial from another supplier is not the same package.
How the two compounds are studied
Each component carries its own single-compound literature. Published in-vitro and preclinical work has examined BPC-157 as a probe for peptide-mediated signalling in cellular models — nitric-oxide-associated processes, growth-factor cascades and cell–matrix interaction behaviour — and TB-500 in actin-binding, cytoskeletal-organisation and cell-migration work, where structural reorganisation rather than a signalling cascade is the readout. The two are chemically unrelated and the mechanisms reported for them are distinct, which is why they appear together more often than any other pair in this catalogue; our BPC-157 vs TB-500 comparison sets them side by side. Published work on the specific combination is close to non-existent, no combined effect is claimed, and "Wolverine" is a market label, not a description of any result. BPC-157 and TB-500 are also supplied as single vials, which is what a control arm needs. These are laboratory observations only, not established effects in humans or animals.
Quality: HPLC purity and the Certificate of Analysis
The chemistry printed above is taken from laboratory certificates rather than reference tables: both peptides in this vial are COA-verified. Every batch is checked by high-performance liquid chromatography at 99%+ purity, and the figure on the certificate is the value recorded for that batch, not a generic claim. A batch-specific COA ships with every order, the two components are certified individually as well, and sample certificates are in the COA library. The material is synthesised and dispatched from our own UK facility rather than imported and relabelled.
Storage and handling
- Refrigerate at 2–8 °C as soon as the parcel arrives; keep the vial sealed and protected from light.
- Do not freeze. Freeze–thaw cycling damages peptides already in solution.
- Draw from the vial using standard aseptic laboratory technique.
- Both components are recorded as clear liquids, so a cloudy or discoloured solution is a reason to check the batch certificate.
Buying the Wolverine Stack in the UK: what to check
- Composition in milligrams per component, not just a total — a blend advertised on its combined mass states the sum, not the split.
- Which TB-500 the certificate describes — the 889.0 g/mol synthetic fragment or the roughly 4,960 g/mol full protein. The same mass of each is not the same preparation.
- A batch-specific Certificate of Analysis naming the batch and the analytical method, viewable before you order.
- Format. Powder needs bacteriostatic water and a reconstitution step; a pre-mixed solution needs cold-chain delivery and a refrigerator.
- What is in the box. Ours ships with the reusable pen and needles, dispatched same-day before 3pm GMT, with free tracked UK delivery on every order and no minimum spend.
- Legal status. Both compounds are lawful to buy and possess in the UK for laboratory research. Neither is a licensed medicine, both are named on the World Anti-Doping Agency's Prohibited List, and every vial is labelled for in-vitro research use only.
Wolverine peptide stack: research FAQs
- What is the Wolverine Stack?
- The Wolverine Stack — also searched as Wolverine peptide or simply Wolverine — is a two-peptide research blend containing BPC-157 (10mg) and TB-500 (10mg), 20mg in total, co-formulated in one vial. BPC-157 is a synthetic pentadecapeptide; TB-500 is a synthetic peptide corresponding to the actin-binding region of thymosin beta-4. Ours is supplied pre-mixed as a solution in a single sealed vial with the reusable pen and needles in the box, and it is labelled strictly for in-vitro laboratory research use only, not for human or veterinary use.
- Is the Wolverine Stack one vial or two?
- One. Both peptides are co-formulated in a single sealed vial as a pre-mixed solution — BPC-157 (10mg) and TB-500 (10mg), 20mg in total — rather than supplied as two separate vials to be combined at the bench. That fixes the composition per batch, so every vial from the same batch is the same preparation. Where a study needs the two varied independently, or a control arm needs one on its own, BPC-157 and TB-500 are also supplied individually.
- What is the Wolverine Stack studied for in research?
- Each component has its own separate laboratory literature. Published in-vitro and preclinical work has examined BPC-157 as a probe for peptide-mediated signalling in cellular models, and TB-500 in actin-binding, cytoskeletal-organisation and cell-migration research. They are supplied together so a laboratory can work with both sequences from one characterised preparation and compare individual against combined activity under the same conditions. Published work on the specific combination is close to non-existent, and no combined effect is claimed. These are laboratory research observations only; they vary with concentration, exposure time and model, and are not established effects in humans or animals.
- What is the difference between the Wolverine Stack, GLOW and KLOW?
- They are a ladder. Wolverine is BPC-157 (10mg) and TB-500 (10mg), 20mg in total. GLOW is that pair plus GHK-Cu (50mg), 70mg. KLOW is GLOW plus KPV (10mg), 80mg. Each step adds one pathway family — copper-dependent signalling with GHK-Cu, then a melanocortin-linked probe with KPV — and a great deal of mass. Wolverine is the narrowest of the three and the only one with no copper complex in the vial, so it is also the only one whose solution is not blue. All three are supplied pre-mixed, strictly for in-vitro laboratory research use only.
- Is your Wolverine Stack pre-mixed or a powder?
- Pre-mixed. Most UK suppliers sell this pairing as a co-lyophilised powder that has to be reconstituted with bacteriostatic water; ours is supplied already in solution in one sealed vial, so there is no reconstitution step and no bacteriostatic water to buy. A solution has to stay cold: every vial ships cold-chain with frozen gel packs inside a sealed foil pouch, should be refrigerated at 2°C–8°C on arrival, kept away from light and never frozen.
- Does the Wolverine Stack come with a pen?
- Yes. The reusable pen and needles are included in the box alongside the sealed pre-mixed vial. It is a reusable volumetric dispensing device rather than a single-use item, and our guide to how the reusable pen works explains its mechanics. A bare vial from another supplier is not the same package.
- Is the Wolverine Stack legal to buy in the UK?
- BPC-157 and TB-500 are legal to buy and possess in the UK for laboratory research purposes. Neither is a licensed medicine and neither can be sold for human or veterinary consumption, and every vial ships labelled for in-vitro research use only. Both are also named on the World Anti-Doping Agency's Prohibited List, which has no bearing on laboratory supply but explains why anti-doping bodies appear alongside these compounds in search results. It is the purchaser's responsibility to ensure their intended research use complies with applicable UK law.
- What purity is your Wolverine Stack, and does it come with a Certificate of Analysis?
- Both peptides are verified at 99%+ purity by HPLC, and the figure printed on each batch's Certificate of Analysis is the value recorded in the laboratory for that batch, not a marketing claim. A batch-specific COA ships with every order, and the two components are certified individually as well, so a per-component certificate exists for each peptide in the vial. Sample COAs can be viewed in our COA library before you buy. The material is synthesised and dispatched from our own UK facility.
- What information do you publish for the Wolverine Stack?
- Composition, chemistry, purity, format, storage and handling — the component masses, the batch Certificate of Analysis and the storage window are the figures we stand behind. The Wolverine Stack is supplied strictly for in-vitro laboratory research, so this page does not describe dosing, administration or use in humans or animals.
