Repair and recovery research peptides
Peptides studied in tissue-repair, angiogenesis and cell-migration assays. BPC-157 and TB-500 are the pair this category is built around, and they work through genuinely different mechanisms, which is why they are so often run together.

How do BPC-157 and TB-500 differ?
BPC-157 is a 15-residue sequence derived from a gastric protein, studied through growth-factor and vascular signalling. TB-500 is the 7-residue actin-binding fragment of thymosin beta-4, studied through actin dynamics and cell migration. Different targets, frequently compared side by side.
Why are they sold as a blend as well as separately?
A co-lyophilized blend removes preparation variance when both are wanted at a fixed ratio. Separate vials keep the ratio adjustable, which matters when the ratio is itself a variable. Both options are here.
What else belongs in this category?
GHK-Cu appears in matrix-remodelling work and KPV in inflammatory signalling; both sit in adjacent categories but are often studied alongside these.
What do the certificates in this category show?
Every vial on this page carries a lot-matched certificate from an independent laboratory, published before the product was listed. Across the 7 lots currently listed here, purity by RP-HPLC at 214 nm runs from 99.68% to 99.8%, and identity is confirmed by LC-MS/MS or MALDI-MS.

Common questions about repair & recovery
Is BPC-157 stable once reconstituted?
Reconstituted peptide is kept at 2-8°C and used within the window your protocol specifies. Sealed lyophilized vials are stored at -20°C. The storage guide covers both.
What is the difference between TB-500 and thymosin beta-4?
TB-500 is the short actin-binding fragment; thymosin beta-4 is the full 43-residue protein. This catalogue lists the fragment, and the product page gives its formula and mass.
Are these for human use?
No. Everything here is sold for in-vitro laboratory research only and is not for human or animal consumption.
