Research peptides
Mechanism of action, molecular specifications, and summaries of the published literature for the most-cited compounds in peptide research. Every entry is reference material for in-vitro laboratory work, not medical guidance.
Retatrutide
Triple agonist (GIP / GLP-1 / glucagon) characterized in Phase 2 metabolic research.
Tirzepatide
Dual GIP and GLP-1 receptor agonist, characterized across the SURMOUNT program.
Tesamorelin
GHRH analog studied for its effects on the GH/IGF-1 axis and on visceral adipose tissue.
GHK-Cu
Copper-binding tripeptide studied for its role in collagen synthesis and remodeling pathways.
BPC-157
Pentadecapeptide derived from gastric juice BPC. The most-cited compound in tissue-repair research.
Ipamorelin / CJC-1295
A ghrelin mimetic paired with a GHRH analog, combining a GH pulse with a longer half-life.
MOTS-c
Mitochondrial-derived peptide studied in metabolic-regulation research.
Ipamorelin
Selective ghrelin-receptor agonist studied as a pulsatile GH secretagogue.
Melanotan II
Melanocortin-receptor agonist studied for pigmentation pathway activity.
TB-500
Thymosin beta-4 and the Ac-LKKTETQ fragment are two different molecules that often get treated as one.
PT-141 (Bremelanotide)
Cyclic melanocortin agonist; the only compound here with an approved finished drug product.
CJC-1295 (DAC)
GHRH analog that conjugates covalently to serum albumin for extended plasma residence.
Semax
ACTH(4-7) fragment extended with Pro-Gly-Pro; studied in neurotrophin and ischemia gene-expression models.
Selank
Tuftsin-derived heptapeptide investigated as a GABA-binding modulator and enkephalinase inhibitor.
Epithalon
A synthetic tetrapeptide studied for telomerase induction. It is not the same thing as the Epithalamin pineal extract.
KPV
C-terminal alpha-MSH tripeptide taken up by PepT1; anti-inflammatory activity independent of MC1R.
AOD-9604
Growth-hormone lipolytic fragment whose obesity program failed its Phase IIb endpoint.
5-Amino-1MQ
A small-molecule NNMT inhibitor, not a peptide. The published literature is small and entirely preclinical.
Cagrilintide
Lipidated amylin analog with a large, precisely reported Phase 3 trial program.
NAD+
Redox cofactor and consumed substrate for sirtuins, PARPs and CD38; central to salvage-pathway research.
Glutathione
The dominant intracellular thiol; its redox couple is a standard readout of cellular oxidative state.
