AOD-9604
1815.1 Da · 17 aa

AOD-9604 is a modified fragment of human growth hormone (amino acids 176-191) that stimulates lipolysis and inhibits lipogenesis without the side effects of full growth hormone. Unlike full GH, it does not increase IGF-1, affect glucose metabolism, or cause insulin resistance.

Cagrilintide
4409.01 Da · 37 aa

Novel long-acting lipidated amylin analog functioning as dual amylin and calcitonin receptor agonist for weight management and type 2 diabetes. Phase 3 trials demonstrate 22.7% weight loss with CagriSema combination.

Full monograph
CJC-1295 (without DAC)
3367.97 Da · 30 aa

Synthetic growth hormone releasing hormone analog with short half-life enabling pulsatile GH secretion patterns resembling natural physiology. Unlike CJC-1295 with DAC, this version preserves natural GH pulsatility without continuous elevation.

Full monograph
CJC-1295 with DAC
3647.28 Da · 30 aa

Modified growth hormone releasing hormone engineered for extended duration via albumin-binding technology. DAC binds to albumin, extending half-life and providing continuous GHRH receptor stimulation.

Full monograph
HGH
22124 Da · 191 aa

Human Growth Hormone (HGH/Somatropin) is a 191-amino acid polypeptide hormone FDA-approved for pediatric and adult growth hormone deficiency, HIV-associated wasting, and other conditions. It provides both direct and indirect (IGF-1 mediated) anabolic effects.

Full monograph
HGH Fragment 176-191
1817.1 Da · 16 aa

HGH Fragment 176-191 is the fat-burning segment of human growth hormone, corresponding to amino acids 176 through 191 of the full GH molecule. It stimulates lipolysis and inhibits lipogenesis without the growth-promoting or insulin-disrupting effects associated with full-length HGH. AOD-9604 is a modified version of this fragment with an added N-terminal tyrosine residue.

Full monograph
Ipamorelin
711.85 Da · 5 aa

Selective GHRP that stimulates natural GH production from the pituitary with minimal cortisol and prolactin disruption. Known for its excellent safety profile and ability to produce consistent GH pulses without significant side effects common to other growth hormone releasing peptides.

Full monograph
Retatrutide
4731.33 Da · 39 aa

Novel triple hormone receptor agonist targeting GLP-1, GIP, and glucagon receptors. Phase II trials demonstrated 24.2% weight loss at 48 weeks—the highest recorded for obesity medications.

Full monograph
Semaglutide
4113.64 Da · 31 aa

Long-acting GLP-1 receptor agonist approved for type 2 diabetes and chronic weight management. Over 17,000 trial participants have demonstrated significant efficacy through appetite suppression and glycemic control. The 7-day half-life enables convenient weekly dosing.

Full monograph
Sermorelin
3358 Da · 29 aa

Sermorelin is a synthetic 29-amino acid analog of human growth hormone-releasing hormone that stimulates natural growth hormone production while preserving physiological pulsatile patterns. Originally FDA-approved in 1997 for pediatric GH deficiency, it was discontinued in 2008 for manufacturing reasons, not safety concerns.

Full monograph
Tesamorelin
5135.9 Da · 44 aa

Tesamorelin is an FDA-approved synthetic GHRH analog designed for HIV-associated lipodystrophy treatment. It provides selective visceral fat targeting with 15-20% visceral fat reduction in clinical trials while preserving subcutaneous fat.

Full monograph
Tirzepatide
4813.55 Da · 39 aa

Revolutionary dual receptor agonist FDA-approved for type 2 diabetes and chronic weight management. Demonstrates efficacy superior to single-mechanism alternatives with 15-22% body weight reduction in clinical trials. The first-in-class dual GIP/GLP-1 agonist provides enhanced metabolic benefits compared to GLP-1-only medications.

Full monograph
GHRP-2
817.9 Da · 6 aa

GHRP-2 is a synthetic growth hormone secretagogue that stimulates the pituitary gland to release growth hormone. It is one of the most potent members of the GHRP family, being 2-3 times more effective than GHRP-6 in stimulating GH release. Originally developed as a diagnostic agent for growth hormone deficiency, it works by mimicking ghrelin and binding to the GHS-R1a receptor.

Partial
GHRP-6
873 Da · 6 aa

GHRP-6 is a synthetic growth hormone secretagogue that stimulates the pituitary gland to release growth hormone. It was one of the first GHRPs developed and works by binding to the ghrelin receptor (GHS-R1a). Unlike direct HGH injections, GHRP-6 enhances the body's natural GH production while keeping negative feedback mechanisms balanced. It is known for its potent appetite-stimulating effects.

Partial
Hexarelin
887 Da · 6 aa

Hexarelin is one of the most potent synthetic growth hormone secretagogues available. It stimulates GH release by binding to the GHS-R1a receptor in the pituitary and hypothalamus, mimicking the action of ghrelin. Notably, Hexarelin demonstrates synergistic effects when combined with GHRH, producing GH responses greater than the arithmetic sum of either peptide alone. It also shows unique cardioprotective properties mediated through the CD36 receptor.

Partial
Mazdutide
4563.1 Da · 33 aa

First-in-class dual GLP-1 and glucagon receptor agonist combining appetite suppression with thermogenesis stimulation. Phase 3 trials demonstrated superiority over semaglutide for weight loss and glycemic control.

Partial
Orforglipron
882.974 Da

First oral non-peptide GLP-1 completing Phase 3 trials. Achieves substantial weight loss without injections, refrigeration, or dietary restrictions, with clinical evidence of 12.4% weight reduction at 72 weeks.

Partial
Survodutide
4500 Da · 29 aa

Investigational dual receptor agonist targeting metabolic disease through balanced GLP-1R and GCGR activation. Phase 2/3 clinical trials demonstrate superior weight loss and MASH treatment efficacy.

Partial
Adipotide

Chimeric adipose-vasculature-targeted peptidomimetic targeting prohibitin/annexin A2 on white adipose tissue endothelium, delivering pro-apoptotic D-(KLAKLAK)2 motif. In obese primates it produced rapid fat loss with improved insulin resistance, yet development halted after Phase 1 due to kidney safety signals.
