FDA-approved peptide medicine
Abaloparatide
Also known as Tymlos, BA058
Synthetic analogue of human parathyroid hormone-related protein (PTHrP 1-34) approved for postmenopausal women and men with high fracture risk osteoporosis.
Alpha-MSH analogue implant (Scenesse) approved to increase pain-free light exposure in adults with erythropoietic protoporphyria; vitiligo is investigational.
Also known as Advanced Obesity Drug 9604, Tyr-hGH 177-191
Modified 16-amino-acid fragment of human growth hormone studied in Phase 2b obesity trials, where it failed to demonstrate significant weight reduction.
An investigational long-acting amylin analogue from Novo Nordisk, studied alone and with semaglutide (CagriSema) in phase 3 obesity and diabetes trials. Not FDA-approved.
Also known as Forzinity, SS-31, MTP-131, Bendavia, Szeto-Schiller peptide
Mitochondria-targeted peptide given FDA accelerated approval (Forzinity) in 2025 for Barth syndrome, based on a very small trial; other trials were negative.
Also known as Acylated Ghrelin, Lenomorelin, Hunger hormone
28-amino-acid acylated gut hormone that activates the growth hormone secretagogue receptor (GHSR-1a) to drive appetite, feeding behavior, and pulsatile GH release.
Also known as Pralmorelin, KP-102, Growth hormone-releasing peptide-2
A synthetic GH-releasing hexapeptide (pralmorelin) used in Japan as a diagnostic test for GH deficiency. Not FDA-approved; FDA flags compounded injectable forms.
Also known as Growth hormone-releasing peptide-6, Growth hormone-releasing hexapeptide, SKF-110679
A synthetic six-amino-acid peptide that triggers growth hormone release via the ghrelin receptor. Used in research and diagnostic tests; not an approved medicine.
Also known as Glucagon-Like Peptide-1, GLP-1 (7-36) amide, Incretin hormone
Primary intestinal incretin hormone that stimulates glucose-dependent insulin secretion; native blueprint for the entire GLP-1 receptor agonist drug class.
Synthetic native GnRH (discontinued U.S. human medicine)
Gonadorelin
Also known as GnRH, LHRH, Factrel, Lutrepulse
Synthetic copy of the brain hormone GnRH. Former U.S. human products (Factrel, Lutrepulse) are discontinued; pulsatile GnRH can restore ovulation in hypothalamic amenorrhea.
FDA-approved peptide medicine / Endogenous hormone
Insulin
Also known as Human Insulin, Regular Insulin, rDNA Insulin
Two-chain 51-amino-acid metabolic peptide hormone central to glucose uptake; essential lifesaving medicine for type 1 diabetes and advanced type 2 diabetes.
Also known as Kisspeptin-10, Kisspeptin-54, Metastin, KP-10, KISS1-derived peptides
Natural hormone that switches on the reproductive axis. Small phase 2 IVF studies used it to trigger egg maturation; no kisspeptin product is approved.
Once-daily GLP-1 receptor agonist approved for type 2 diabetes and chronic weight management, with extensive long-term cardiovascular outcome trial data.
FDA-approved GLP-1 receptor agonist (U.S. supply now only in the Soliqua combination)
Lixisenatide
Also known as Adlyxin, Lyxumia, AVE0010, Soliqua 100/33
Once-daily GLP-1 receptor agonist for type 2 diabetes. Standalone Adlyxin is no longer marketed in the U.S.; lixisenatide remains available in Soliqua 100/33.
A once-weekly GLP-1/glucagon dual agonist approved in China in 2025 for weight management and type 2 diabetes. Investigational and not FDA-approved in the U.S.
An investigational once-weekly GLP-1/glucagon dual agonist from Altimmune. Phase 2 trials show liver-fat reduction and MASH resolution; a phase 3 MASH trial is recruiting.
Also known as PYY, PYY (3-36), Pancreatic Peptide YY3-36
Postprandially secreted enteroendocrine L-cell peptide that acts as an ileal brake via central Y2 receptors to suppress appetite and slow gastric emptying.
An investigational once-weekly GIP, GLP-1 and glucagon receptor agonist from Eli Lilly. Phase 3 obesity and diabetes trials report large weight loss; not FDA-approved.
Long-acting GLP-1 receptor agonist proven in large Phase 3 RCTs for type 2 diabetes glycemic control, obesity weight reduction, and cardiovascular risk reduction.
A 29-amino-acid fragment of GHRH. It was FDA-approved as Geref for pediatric GH deficiency and testing, then discontinued in 2008 for reasons unrelated to safety.
Dual GIP and GLP-1 receptor co-agonist approved by FDA for type 2 diabetes and chronic weight management following SURPASS and SURMOUNT clinical trials.
