Research Profile

  • Two-peptide research blend
  • BPC-157 + TB-500 at matched strengths
  • Single lyophilised vial or pre-filled research pen
  • Each component HPLC-verified independently
  • Research use only

The Wolverine Stack co-formulates the two compounds most frequently paired in the preclinical tissue-repair literature. BPC-157 is a synthetic pentadecapeptide derived from a partial sequence of human gastric juice protein, characterised in the Sikiric group's tendon and gut-mucosal models. TB-500 is a synthetic fragment of Thymosin Beta-4, characterised for its role in actin sequestration and cellular migration. Supplying both in one vial at matched strengths removes the need to reconstitute and handle two separate preparations. Supplied for in-vitro research use only.

The above describes how these compounds are characterised in the published peer-reviewed literature. It is not a claim about effects in humans.

Laboratory Handling

The Wolverine Stack is supplied as a lyophilised (freeze-dried) powder in a sealed glass vial. For laboratory reconstitution, add the desired volume of diluent (typically bacteriostatic water) slowly down the side wall of the vial. Swirl gently until fully dissolved - do not vortex or shake. Store reconstituted solutions at 2–8 °C and use within 4–6 weeks.

Use our Reconstitution Volume Calculator to compute the resulting mg/ml concentration. Note that a 10 mg / 10 mg vial reconstituted in 2 ml yields 5 mg/ml of each component.

Purity & Verification

Every batch of the Wolverine Stack we supply is independently HPLC-verified by Janoshik Analytical, with each component tested separately before blending. Where a Janoshik report has been issued for the current batch it is supplied with the order and carries a unique verification key that can be authenticated against Janoshik's records. Reported purity is consistently above 99%.
