What is the Wolverine Stack?
Short answer
The Wolverine Stack is a compounded blend of BPC-157 and TB-500 in one vial. BPC-157 is a 15-amino-acid fragment of a gastric protein; TB-500 is a 17-amino-acid fragment of thymosin beta-4. Both have been studied in animal models of tissue repair, and no trial of the combination has been published. It is prescription-only, compounded, not FDA-approved, and prohibited in sport.

What is in the Wolverine Stack?
The Wolverine Stack is two peptides, BPC-157 and TB-500, dissolved together in one vial. BPC-157 is a synthetic 15-amino-acid fragment of a protective protein first isolated from human gastric juice. TB-500 is a synthetic 17-amino-acid fragment of thymosin beta-4, a 43-amino-acid protein, covering the region that binds actin, the protein cells use to move and to build internal structure.
The name is a nickname, borrowed from a comic-book character, and it has no connection to any study. Underneath it is a straightforward co-formulation: a compounding pharmacy prepares both sequences and combines them at a fixed ratio printed on the label.
What has the Wolverine Stack been studied for?
The Wolverine Stack as a combination has not been studied in any published trial. What exists is separate literature for each compound. For BPC-157, reviews describe animal work on tendon, ligament, muscle and bone healing, on gut lesions, and on new blood vessel formation, with interactions described in the nitric oxide and growth-factor systems. For TB-500 and its parent protein thymosin beta-4, the review in the references covers basic properties and clinical applications, and the animal studies center on cell migration and tissue repair.
The two are paired because the research areas overlap: both are described in reviews in the context of soft-tissue and connective-tissue repair. Overlap in animal literature is not evidence that the combination does anything in people, and no large human trial of either compound has been published, let alone of the blend.
| Compound | Type of evidence | What the reviews describe |
|---|---|---|
| BPC-157 | Animal models, reviews | Tendon, ligament, muscle and gut repair models; angiogenesis and nitric oxide pathways |
| TB-500 | Animal and cell studies, one review of thymosin beta-4 | Cell migration tied to actin binding; wound and injury models |
| The combination | No published trials | Nothing; the pairing rests on overlapping preclinical areas |

How is the Wolverine Stack prescribed?
The Wolverine Stack is prescribed in the US as a compounded medication: a licensed provider reviews an individual's intake and history, writes a prescription, and a licensed 503A pharmacy prepares the blend. Through Peptides.build it is prescribed as a subcutaneous injection and ships already reconstituted, with each peptide's concentration printed on the pharmacy label, so there is no powder to mix and no water to add.
Because both peptides share one liquid, every draw carries both in the vial's ratio, and the amounts cannot be adjusted separately. A prescription that calls for a different balance means a different blend or two separate vials, which is a question for the prescriber and pharmacy. BPC-157 is also available on its own, and the provider decides whether the single compound or the pair fits; dosing is set by the provider and never published on this site.
Is the Wolverine Stack FDA-approved or allowed in sport?
The Wolverine Stack is not FDA-approved for any use, and neither BPC-157 nor TB-500 is FDA-approved on its own. It is a compounded medication, and compounded medications are not FDA-approved. That is the status of every protocol in this catalog.
In sport the stack is doubly prohibited: the World Anti-Doping Agency lists both BPC-157 and TB-500 among non-approved substances, banned at all times. Drug-tested athletes should check with their governing body before considering it.
How are Wolverine Stack doses measured?
The Wolverine Stack prescription states the BPC-157 amount, written in micrograms, and the TB-500 follows at the ratio on the label. The free BPC-157 calculator on this site has a blend mode for exactly this vial: enter the BPC-157 dose from the prescription and both label strengths, and it returns the units to draw on a U-100 insulin syringe and the amount of TB-500 that comes with them. It performs arithmetic only and does not recommend a dose.
Prescribed Wolverine Stack (BPC-157 / TB-500) vs research peptides: what is different?
Prescribed Wolverine Stack (BPC-157 / TB-500) is not a research chemical. It is a prescription medication: a licensed US provider reviews your intake first, and a licensed 503A pharmacy compounds it for you by name. Vials sold online as “research use only” skip both steps. What you pay for here is that review, a pharmacy you can name, and a label that says what is in the vial.
A research seller’s certificate of analysis is a document the seller controls: it chooses the lab and the sample, and a PDF can be reused, edited or re-dated. No regulator checks it.
| Point | Prescribed through Peptides.build | Research use only |
|---|---|---|
| Access | Online intake reviewed by a licensed US provider; prescribed only when appropriate. | No prescription and no clinical review of whether it suits you. |
| How it's labeled | A prescription medication compounded for you by name. | Commonly sold labeled “research use only, not for human consumption.” |
| Who prepares it | A licensed 503A US compounding pharmacy under state and federal oversight. | Unregulated suppliers, often with no verifiable chain of custody. |
| Testing | Third-party tested. | Certificates of analysis are self-reported when provided at all. |
| Purity and identity | Prepared to a prescription for a specific patient. | Purity, strength, and even identity are unverified by any independent party. |
This compares two care models, not two products. Compounded medications are not FDA-approved, and we do not claim otherwise. What a prescription adds is a licensed provider deciding whether a protocol is appropriate for you and a licensed pharmacy preparing it. Read the full guide to research vs prescription peptides.
Wolverine Stack (BPC-157 / TB-500) FAQ
Why is it called the Wolverine Stack?
The name is a nickname taken from a comic-book character, not from a study or a pharmacy. The product underneath it is a compounded blend of BPC-157 and TB-500 at a fixed ratio; the name says nothing about evidence.
Is the Wolverine Stack better than BPC-157 alone?
No published trial compares the two. TB-500 adds a second compound with its own animal research, and a second variable for the provider to weigh. Whether one or both fits your history is a provider decision at intake.
Has the Wolverine Stack been tested in humans?
No. There is no published human trial of the BPC-157 and TB-500 combination, and no large human trials of either compound on its own. The research is animal and review literature.
Is the Wolverine Stack legal in the US?
It is available only as a compounded medication prescribed by a licensed provider and prepared by a licensed 503A pharmacy. Neither compound is FDA-approved for any use, and compounded medications are not FDA-approved.
Can athletes use the Wolverine Stack?
Drug-tested athletes should not. BPC-157 and TB-500 are both on the World Anti-Doping Agency Prohibited List as non-approved substances, banned at all times. Check with your governing body.
Wolverine Stack through Peptides.build
A licensed US provider reviews a short online intake and decides whether a protocol is appropriate. A US 503A pharmacy prepares it already reconstituted, labels the concentration and ships it cold-chain. Dosing is set by the provider and is not published on this site.
