Single peptide vs blend

Wolverine Stack vs BPC-157 alone: one compound apart, different legal status

Updated 路 Prices from the live catalog

The short answer

The Wolverine Stack is BPC-157 plus TB-500 in one vial. BPC-157 alone is a single ingredient and is covered by the HHS policy of October 28, 2026; the Wolverine Stack is a blend, so it is outside that policy, and it is still prescribed by a licensed US provider after an intake. At Peptides.build BPC-157 is $163 month to month ($158/mo on 6 months) and the Wolverine Stack is $225 ($183/mo). Both ship already reconstituted from a licensed 503A pharmacy.

The one difference

What does TB-500 add?

TB-500 is a synthetic 17-amino-acid fragment of thymosin beta-4, covering the region that binds actin, the protein cells use to move and hold their shape. Its research is animal and cell work on cell migration and tissue repair, and much of the literature is about the full parent protein rather than the fragment. Read BPC-157 vs TB-500.

BPC-157 is a 15-amino-acid fragment of a protective protein first found in gastric juice, studied in preclinical research for tendon, ligament, muscle and gut repair pathways. It has the larger and more compound-specific literature of the two. Neither has a large published human trial, and nobody has tested the pair together, so claims that they are synergistic have no trial behind them. See What is the Wolverine Stack?

Regulatory status

Is BPC-157 legal, and is the Wolverine Stack?

Since October 28, 2026, HHS says it will not take enforcement action against a licensed 503A pharmacy or physician compounding BPC-157 acetate for a patient with a prescription, by injection, oral or topical route, if ten conditions are met. One of those conditions is a single active ingredient. So BPC-157 alone is covered, and the Wolverine Stack is outside the policy. Peptides.build still offers it when a licensed US provider prescribes it after an intake, compounded by a licensed 503A pharmacy. Neither is FDA-approved; compounded medications are not FDA-approved. Details on is BPC-157 legal and which peptides are legal.

How it is decided

How does a provider choose between them?

  • Simplicity. The single peptide is the simpler protocol with the deeper literature.
  • Fixed ratio. In the stack both peptides share one liquid, so every draw carries both in the vial's ratio and they cannot be adjusted separately.
  • Policy status. If you want a product inside the HHS policy, BPC-157 alone is; the blend is not.
  • Your history. A licensed US provider reviews your intake and decides whether either fits. Dosing is set by the provider and is never published on this site.

Common questions

FAQ

What is the difference between BPC-157 and the Wolverine Stack?

One compound. The Wolverine Stack is BPC-157 with TB-500, a synthetic fragment of thymosin beta-4, in the same vial. BPC-157 on its own is the single peptide.

Is the Wolverine Stack better than BPC-157 alone?

No published trial compares them, and no trial of the combination exists. TB-500 adds a second compound with its own animal research, and a second variable for the provider to weigh. Which fits your history is a provider decision at intake.

Why are BPC-157 and TB-500 prescribed together?

Their preclinical research areas overlap: both are described in reviews in the context of soft-tissue and connective-tissue repair. Overlap in animal studies is not evidence that the pair does anything in people.

Which one costs less?

BPC-157: $163 month to month, $499 for 3 months or $949 for 6 months. Wolverine Stack: $225, $599 or $1,099. Review, compounding and shipping are included in both.

Is the Wolverine Stack covered by the HHS peptide policy?

No. The policy covers products with one active ingredient only. BPC-157 alone is covered, as acetate by injection, oral or topical route. The Wolverine Stack is outside it and is still prescribed by a licensed provider after an intake.

Can I get TB-500 on its own instead?

TB-500 alone is one of the six peptides the HHS policy covers, but it is not offered here as a single-ingredient protocol. At Peptides.build TB-500 is only available inside the Wolverine, Glow and KLOW stacks.

Are BPC-157 and the Wolverine Stack FDA-approved?

No. Neither BPC-157 nor TB-500 is FDA-approved for any use, and compounded medications are not FDA-approved.

Is BPC-157 allowed in drug-tested sport?

No. BPC-157 and TB-500 are both on the World Anti-Doping Agency prohibited list, banned at all times, so the stack is doubly prohibited. Check with your governing body.

Is there anything else to stack with BPC-157?

At Peptides.build, BPC-157 is also part of the Glow Stack (with GHK-Cu and TB-500) and the KLOW Stack (adds KPV). Both are blends outside the HHS policy. A provider decides whether any combination fits you.

Prescribed, not mixed at home

Tired of reconstituting?

A licensed US provider reviews a short online intake. If a prescription is appropriate, a licensed US 503A pharmacy fills it and ships it cold-chain, already reconstituted and labeled with the concentration.
