Peptide blend
BPC-157 and TB-500 are commonly run together as a recovery-focused “Wolverine” stack. This page collects the reconstitution and same-syringe co-draw math for the pair, plus the reference data reported for each. It is provided strictly for reference and is not medical advice or a recommendation to use either peptide.

Plan the BPC-157 + TB-500 co-draw
Reconstitute each peptide in its own vial, then plan the same-syringe co-draw — the tool works out the concentration and U-100 units to draw for each. Both are set below; edit the vial size, water, and dose to match your own. Arithmetic only — not medical advice.
BPC-157 + TB-500 co-draw calculator X
Reconstitute each vial, then plan the same-syringe co-draw and read U-100 units for each.
Arithmetic checks out. Confirm clinically, against the label, and against the actual vial before any use.
Independent check - dose mg / concentration mg/mL = volume. U-100 units = mL x 100.
Same-syringe co-draw. Reconstitute each peptide in its own vial, then draw them into one syringe.
- Reconstitute each peptide in its own vial — never add water to multiple peptides in one vial.
- Only co-draw peptides with the same diluent (e.g. both bacteriostatic water) and compatible pH.
- Draw and inject fresh — do not pre-mix and store; mixture stability is not established.
- No blended stack is clinically validated. Verify each component and confirm with a clinician.
How the BPC-157 + TB-500 stack is used
BPC-157 and TB-500 are frequently combined in a so-called “Wolverine” recovery stack, on the rationale that they work through different mechanisms. That rationale rests on anecdote and animal data, not human trials: neither peptide is FDA-approved, the FDA reports limited safety information for BPC-157, and it lists the TB-500 (LKKTETQ) fragment as a potential significant compounding safety risk. No blended stack is clinically validated. The figures here are reconstitution and co-draw arithmetic only — not a dose recommendation or a claim that the stack is safe or effective.
Reference and arithmetic only. Not medical advice; verify with a clinician, product label, pharmacist, or approved research protocol.
Frequently asked questions
How are BPC-157 and TB-500 administered?
Neither has an established human treatment route or regimen. Both are research peptides that are not FDA-approved, and the FDA has flagged safety concerns — including listing the TB-500 fragment as a potential significant compounding safety risk. The table above summarizes this.
What is the BPC-157 + TB-500 “Wolverine” stack?
It is an informal combination of two research peptides — BPC-157 and TB-500 — run together for recovery. It has no established human dose range, so none is quoted here. The calculator still performs the reconstitution and co-draw arithmetic for whatever inputs you enter; it does not tell you what dose to take.
Can I calculate reconstitution for both here?
Yes — the buttons above open each calculator to convert vial strength and bacteriostatic water into concentration (mg/mL), draw volume and U-100 syringe units. It is arithmetic only.
Does this page recommend the stack?
No. It is a neutral reference that reflects the limited information available, and it does not assess the safety, efficacy, or suitability of the stack for anyone. Consult a qualified professional.
