← Shelf·Two-peptide combination stack (BPC-157 + TB-500/TB-4)·XXXI.
Wolverine Stack.
A vendor-formulated combination of two research peptides — BPC-157 (a synthetic 15-amino-acid pentadecapeptide derived from a sequence in Body Protection Compound, a stomach-lining protein) and TB-500 (a 17-residue fragment of the endogenous protein thymosin β-4). Each constituent has its own decades-long literature record; the combination itself is a marketing construct, not a published research protocol. Sold in a single lyophilized vial at approximately a 1-to-1 mass ratio (5.32 mg BPC-157 + 5.11 mg TB-500 per 10 mg vial, per the vendor's lot COA).
The stack itself is not endogenous — it is a laboratory-manufactured combination. BPC-157 is a synthetic fragment; its parent sequence comes from Body Protection Compound, a protein produced in the stomach lining. TB-500 corresponds to the active 17-residue fragment of thymosin β-4, a naturally-occurring cytoskeletal-regulatory protein. Where each ingredient comes from is covered in its own entry.
Marketed across the peptide-user community as a synergistic stack with combined benefits — the two-in-one shortcut. That framing has no published human trial data behind it in this specific ratio. The consumer marketing treats the sum as evidence-based when only the parts are individually documented, and even the parts are documented mostly in preclinical work.
Straight talk
Straight talk: there is not a single published human clinical trial of BPC-157 + TB-500 as a combination in the ratios sold. Every claim you will see about the stack is either (a) an extrapolation from single-compound preclinical work on one of the constituents or (b) anecdotal community reporting. The individual peptides' evidence bases are what they are — inspect them in the BPC-157 and TB-500 entries — and both are thin at the human-trial level. Combining two research compounds does not add evidence; it multiplies uncertainty.
What the research studies
The literature, not a summary of it.
There is no literature on this specific combination. What exists is the literature on each constituent, which is best consulted in the individual entries. For a combination-level search — expect essentially zero hits at the human-trial level — read the research yourself:
