Best peptides for recovery

BPC-157 (Body Protection Compound-157) is a synthetic 15-amino-acid pentadecapeptide derived from a gastric protective protein. It has the broadest preclinical evidence base of any recovery peptide — animal studies across tendon, muscle, bone, gut, and nerve tissue showing tissue regeneration effects via NO-pathway activation and VEGF upregulation. Human evidence is limited to a single safety pilot with n=2.

TB-500 is a synthetic fragment of thymosin beta-4, an endogenous protein involved in actin sequestration and cytoskeletal remodeling. Animal models show cardiac tissue repair and angiogenesis effects. Frequently co-administered with BPC-157 in community protocols due to their proposed complementary mechanisms. No human clinical trials have been published.

GHK-Cu is a naturally occurring tripeptide-copper complex found in human plasma. Cell culture and animal studies show wound healing, collagen synthesis stimulation, and anti-inflammatory effects via VEGF upregulation and matrix metalloproteinase modulation. Also used topically in cosmetic formulations, where it has the most accessible human-use data of the compounds on this list.

KPV (Lys-Pro-Val) is a tripeptide derived from the C-terminal sequence of alpha-MSH. Animal models of inflammatory bowel disease show gut-protective and anti-inflammatory effects via MC1R signaling in gut epithelium. Its recovery application is specifically inflammation-mediated; it is not a general tissue-repair compound. No human clinical trials have been published.
