BPC-157 is a synthetic pentadecapeptide sequence derived from gastric-juice protein fragments. It is among the most discussed catalog peptides in connective-tissue and gastrointestinal preclinical literature — with a large but investigator-concentrated rodent bibliography.
TB-500 commonly refers to a fragment or analog related to thymosin beta-4 actin-binding biology. Catalog naming is inconsistent — full-length Tβ4, fragments, and mislabeled products all appear in commerce.
Abaloparatide is an FDA-approved PTHrP analog studied in the ACTIVE phase 3 trial for postmenopausal osteoporosis. Sequence and signaling profile differ from teriparatide despite shared peptide length.
Angiotensin (1-7) is a heptapeptide metabolite of the renin-angiotensin system studied as a counter-regulatory arm opposing Ang II signaling, with cardiovascular and fibrosis research literature.
B7-33 is a minimized relaxin-2 analog designed as a biased RXFP1 agonist with anti-fibrotic activity in rodent organ models. Not FDA-approved; distinct from native two-chain relaxin.
MGF in literature refers to IGF-1Ec, an IGF-1 splice variant up-regulated after muscle stress. Catalog MGF usually means a synthetic 24-mer E-peptide — not proven as an isolated endogenous product.
PEG-MGF is a pegylated synthetic MGF E-domain peptide engineered for extended half-life. It does not exist endogenously; most systemic MGF animal data use pegylated rather than native peptide.
Teriparatide is FDA-approved PTH(1-34) for high-risk osteoporosis. Fracture Prevention Trial data established vertebral and nonvertebral fracture reduction — a formal clinical tier distinct from catalog repair peptides.
Thymosin beta-4 is the full-length actin-binding protein underlying TB-500 fragment commerce. Phase 2 wound and corneal trials exist; catalog fragments require separate sequence confirmation.
