![BPC + TB 20mg [10+10]](https://thenextlab.co/wp-content/uploads/2026/05/altlab-vial-bpc-tb.webp?v=nl5)
A two-peptide research blend: BPC-157, a 15-amino-acid peptide first found in stomach fluid, paired with TB-500 — the active fragment of the Thymosin β-4 protein.
Research on BPC-157 has looked at tendon and muscle healing models. Separate studies on the TB-4 fragment have looked at blood-vessel formation and cell migration, with research effects that persist in tissue after the peptide clears the bloodstream. The two are studied together to see how their research effects overlap.
Identity
BPC-157 10 mg · CAS 137525-51-0
TB-500 fragment 10 mg · LKKTETQ · CAS 77591-33-4
≥99% HPLC each · 20 mg total · 3 mL vial
This blend co-formulates BPC-157, a synthetic 15-amino-acid peptide derived from a sequence in human gastric juice, with the TB-500 fragment of Thymosin β-4, whose central LKKTET motif binds G-actin. Published rodent literature on BPC-157 has examined tendon outgrowth, cell migration, and angiogenic markers in muscle and tendon injury models. Separate literature on the Thymosin β-4 fragment has examined actin-binding-dependent effects on dermal wound closure and post-traumatic tissue endpoints.
