BPC-157 (Body Protection Compound 157) is a stable 15-amino-acid pentadecapeptide fragment derived from a gastric juice protein, supplied by CertaPeptides as a lyophilized laboratory research compound (≥98% supplier batch specification; selected lots independently tested, 99.3% avg across published reports; CAS 137525-51-0). In preclinical literature, Sikiric et al. (2014, PMID 23755725) reported effects on the nitric oxide system in rodent models, and Chang et al. (2014, PMID 25415472) observed increased growth hormone receptor expression in cultured tendon fibroblasts. These findings are reported here for research context only and are not medical claims. For laboratory research use only. Not for human consumption.

TB-500 is a synthetic peptide corresponding to the 17-amino acid active region (Ac-SDKP sequence) of Thymosin Beta-4, a naturally occurring 43-amino acid protein. While the full-length Thymosin Beta-4 molecule has broad biological activity, TB-500 retains the key actin-binding domain that drives research interest in cell migration and tissue biology. Shipped to a ≥98% supplier batch specification; selected lots independently tested (99.3% avg across published reports). Key research areas: Cell migration and tissue remodeling Actin-binding and cytoskeletal dynamics Cardiac tissue biology and cellular signaling Important distinction: TB-500 is a fragment of Thymosin Beta-4, not a synonym for it. Full-length Thymosin Beta-4 (43 aa) has broader systemic activity, while TB-500 (17 aa) retains the active actin-sequestering region. For research purposes only. Not for human consumption.

GHK-Cu is a naturally occurring copper-binding tripeptide (Glycyl-L-histidyl-L-lysine copper complex) studied extensively in tissue biology and cellular remodeling research. Concentration declines with age, making it a key compound in age-related biological studies. Shipped to a ≥98% supplier batch specification; selected lots independently tested (99.3% avg across published reports). Key research areas: Tissue remodeling and extracellular matrix pathways Collagen and decorin synthesis stimulation Gene expression modulation (over 4,000 genes identified) For research purposes only. Not for human consumption.

Epitalon is a 4-amino acid synthetic tetrapeptide (Ala-Glu-Asp-Gly) studied for telomerase activation and telomere biology research. Derived from pineal gland epithalamin.
