The Wolverine Stack: BPC-157 + TB-500
“Wolverine” is a nickname the research community gave this pairing, not a formulation. No laboratory named it, no monograph defines it, and nothing stops two vendors putting the word on two different mixtures. That matters more than it sounds: when you compare two products called a Wolverine stack, you are comparing marketing names, and the only way through is to read what is actually in the vial.
View product →What the Wolverine stack is
In its standard form it is two peptides supplied together:
- BPC-157: a fifteen amino acid fragment of a protein found in gastric juice. Studied across soft tissue, tendon and ligament models, with a substantial body of gastrointestinal work behind it.
- TB-500: a synthetic peptide corresponding to the active region of thymosin β4. Associated in the literature with cell migration, tissue regeneration and new blood vessel formation.
The reason they are paired is that they are studied around related but distinct mechanisms rather than the same one. That is the entire logic of the stack, and it is also why the pairing acquired a nickname in the first place.
Where the name came from
It is a comic-book reference: the character whose defining trait is rapid healing. It spread through forums and community write-ups rather than from any vendor or paper, which is exactly why it has no fixed meaning. You will also see it written Wolverine blend, Wolverine peptide stack, Healing Blend or just the Wolverine peptide. They all point at the same BPC-157 and TB-500 pairing.
The number that actually matters
Because nothing standardises the name, the specification is the only thing worth comparing. Two figures decide it:
- The total milligrams in the vial, and
- the split between the two peptides.
A cheaper Wolverine stack with a lower total is not cheaper, and a listing that states neither number cannot be compared with anything. Vistara Labs lists what is in the vial on the product page, 5 mg of each peptide in the 10 mg size and 10 mg of each in the 20 mg size, so the comparison is straightforward.
Buying it in Canada
They are supplied as research materials, and the Wolverine stack comes as a single freeze-dried vial holding both peptides together.
Canadian fulfilment. Orders ship from within Canada by domestic post to every province. The vial arrives sealed and ready for storage, with both peptides and the milligram split named on the product page.
Questions are welcome. Our team answers questions about the blend, its two sizes or an order through our contact page.
Wolverine stack format and specification
- Both peptides named. The Wolverine stack is BPC-157 and TB-500, and both are named on the listing rather than grouped under a general label such as “recovery blend”.
- A stated milligram total. The blend comes in a 10 mg and a 20 mg vial, and the total is stated on the product page for each size.
- An intact white cake. Both peptides are white lyophilised powders, and the blend arrives as a single freeze-dried cake, the form that keeps peptides stable through storage and shipping.
- Published certificates. Certificates of analysis from independent laboratories are published for each compound on our lab reports page, and the blend we stock is above 99 percent purity.
- Research-use framing. This pairing attracts a large volume of informal recovery talk, precisely because of the nickname. The stack is supplied for laboratory research only, and our listing describes the compounds, the split and the format.
The stack, or the peptides separately?
Buying the blend is generally the cheaper route and gives you both compounds in a single vial. Buying them separately (BPC-157 and TB-500 as individual vials) costs more but leaves the ratio in your hands rather than the vendor’s. Which is right depends entirely on whether the work needs the two held independently.
A clinical data point worth knowing: in a 2021 retrospective study, 87.5% of knee-pain patients reported relief after intra-articular BPC-157, given alone or with TB-500. We break down the numbers in our BPC-157 and TB-500 knee-pain study analysis.
Vistara Labs stocks the BPC-157 + TB-500 blend, in two sizes, shipped from within Canada to every province.
Frequently asked questions
Why is it called the Wolverine stack?
It is a comic-book reference to the character known for rapid healing. The name came from community forums rather than from any vendor or published paper, which is why it has no standard definition.
What is in a Wolverine peptide stack?
Ordinarily BPC-157 and TB-500 supplied together in one lyophilised vial. The Vistara Labs blend states the split on the product page: 5 mg of each in the 10 mg size and 10 mg of each in the 20 mg size.
Is the Wolverine stack the same as BPC-157 on its own?
No. BPC-157 alone is a single peptide; the stack pairs it with TB-500, which is studied around a different set of mechanisms. The pairing is the point.
Can you buy the Wolverine stack in Canada?
Yes, as a research material from Canadian research suppliers. Neither peptide is approved as a medicine in Canada.
Will a Wolverine stack order be stopped at customs?
No. Every Vistara Labs order ships from within Canada, so there is no customs step, just an ordinary domestic parcel moving between two Canadian addresses.
