BPC-157
BPC-157 is a synthetic 15-amino-acid peptide (pentadecapeptide) with the sequence GEPPPGKPADDAGLV, originally described as isolated from human gastric juice and studied mainly in animal models of…
Retatrutide
Retatrutide is a 39-residue synthetic lipidated peptide that acts as a triple agonist at the glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1) and glucagon receptors. Developed…
Tesamorelin
Tesamorelin is a synthetic 44-amino-acid analogue of human growth hormone-releasing hormone (GHRH) carrying an N-terminal trans-3-hexenoyl group. It stimulates release of the body's own growth hormone…
MOTS-c
MOTS-c is a 16-amino-acid mitochondrial-derived peptide encoded by a short open reading frame within the mitochondrial 12S rRNA gene. First reported in 2015, it has been…
GHK-Cu (Copper Tripeptide-1)
GHK-Cu is the copper(II) complex of glycyl-L-histidyl-L-lysine (GHK), a tripeptide that occurs naturally in human plasma, saliva and urine. Also called copper tripeptide-1 or prezatide copper,…
