Repair & Recovery Research Peptides

Repair-class research peptides are studied in laboratory and animal models for their effects on tissue remodeling, angiogenesis, cell migration, and inflammatory signaling. The class includes peptides derived from naturally-occurring tissue-protective proteins (BPC-157, derived from a sequence within gastric juice), thymosin family peptides (TB-500, a synthetic Thymosin Beta-4 analog), and metal-binding tripeptides (GHK-Cu, the copper-bound form of Glycyl-Histidyl-Lysine). Each has a distinct receptor-and-signaling profile but shares broadly relevant research applications in tissue-repair biology.

BPC-157 is a 15-amino-acid sequence (full sequence: GEPPPGKPADDAGLV) studied extensively in animal models of tendon, ligament, muscle, and gastrointestinal tissue repair. Research literature characterizes proposed mechanisms including effects on VEGF expression, NO synthase activity, and growth-factor signaling. Our BPC-157 is supplied at 10mg per vial as lyophilized powder. Note: some research supplies refer to "BPC-157 Arginate" or "BPC-157 Acetate" salt forms — consult the lot-specific COA for salt form and net peptide weight.

TB-500 is a synthetic peptide based on the active 17–23 region of Thymosin Beta-4 (TB4), a 43-amino-acid actin-sequestering peptide naturally present in many tissues. TB-500 is studied for its effects on actin polymerization, cell migration, and angiogenesis — particularly in cardiac, dermal, and skeletal-muscle research models. We supply both the full TB-500 (5mg, 10mg) and the TB-500 (17-23) Fragment (5mg, 10mg) for researchers studying the active site specifically.

GHK-Cu is the copper-bound form of the tripeptide Glycyl-Histidyl-Lysine. Research literature characterizes effects on dermal fibroblast activity, matrix metalloproteinase regulation, and gene-expression patterns relevant to skin biology and wound research. We supply GHK-Cu at 50mg and 100mg per vial. Note that GHK-Cu solutions are light-sensitive — store reconstituted material in amber vials or shielded from direct illumination.

Lyophilized repair peptides are stable at -20°C for extended periods. Post-reconstitution, store at 2–8°C and minimize freeze-thaw cycles. BPC-157 in solution is generally stable refrigerated for 14–28 days. TB-500 reconstituted solutions show similar stability. GHK-Cu solutions should be protected from direct light and used within the lot-specific stability window. Always reconstitute with bacteriostatic water using sterile technique.
