Peptide Research Guides
Evidence-based educational overviews of researched peptides, grounded in published literature. Each guide clearly separates human research from preclinical (animal/lab) findings and notes the current maturity of the evidence. Educational and research use only — not medical advice.
BPC-157
Primarily preclinicalBPC-157 is a synthetic peptide studied mainly in animal models for its investigated effects on soft-tissue and gut-lining repair. The research base is overwhelmingly preclinical — robust human clinical evidence is currently very limited.
TB-500
Primarily preclinicalTB-500 is a synthetic peptide related to a fragment of the naturally occurring protein Thymosin Beta-4 (Tβ4). Research into its investigated roles in cell migration and tissue repair is largely preclinical; direct human evidence for TB-500 specifically is minimal.
GHK-Cu
Topical human data + preclinicalGHK-Cu is a naturally occurring copper-binding tripeptide most studied in skin and wound-healing contexts. Topical/cosmetic use has some human data, while systemic and injectable applications remain largely preclinical.
SS-31
Clinical-stage researchSS-31 — developed clinically as elamipretide — is a mitochondria-targeting peptide that has advanced into human clinical trials for several mitochondrial and age-related conditions. It is investigational and not an approved treatment.
MOTS-c
Primarily preclinicalMOTS-c is a mitochondrial-derived peptide investigated for its roles in metabolism, insulin sensitivity, and exercise/aging biology. The research is largely preclinical with early, emerging human interest.
