29 amino acids

CJC-1295

is used in research to chronically elevate endogenous growth hormone and IGF-1 levels, enabling studies of body composition, metabolic, and anti-aging effects of prolonged GH exposure

5 amino acids

Ipamorelin

is investigated for producing moderate, physiologic-like GH pulses useful for studying anabolic, body-composition, and recovery effects with a relatively clean endocrine side-effect profile compared with earlier GHRPs

29 amino acids

Sermorelin

is used as a diagnostic agent for assessing GH secretory capacity and as a research tool or off-label therapy to increase endogenous GH in GH-deficient or age-related contexts

44 amino acids

Tesamorelin

is FDA-approved to reduce excess visceral adipose tissue in HIV-associated lipodystrophy and is studied for broader body-composition, NAFLD, and cognitive effects via GH/IGF-1 axis modulation

6 amino acids

GHRP-2

is used in research to induce robust GH pulses and study anabolic and metabolic effects; clinically developed as pralmorelin for GH deficiency diagnostics

6 amino acids

GHRP-6

is used experimentally to produce strong GH surges and hyperphagia, allowing investigation of GH-dependent anabolism and energy-balance regulation

6 amino acids

Hexarelin

is investigated for effects on GH secretion, cardiac protection, and muscle metabolism, with higher GH secretory potency than earlier GHRPs

31 amino acids

Semaglutide

is approved for type 2 diabetes and chronic weight management, significantly lowering HbA1c and body weight by modulating incretin pathways

39 amino acids

Tirzepatide

is approved for type 2 diabetes and obesity, producing larger HbA1c and body-weight reductions than semaglutide in head-to-head trials

39 amino acids

Retatrutide

is an investigational agent that produces very large body-weight reductions in early trials by simultaneously engaging GLP-1R, GIPR, and GCGR to enhance satiety, energy expenditure, and glycemic control

31 amino acids

Liraglutide

is approved for type 2 diabetes and weight management, improving glycemic control and inducing weight loss through GLP-1–mediated insulinotropic, glucagonostatic, and appetite-suppressing actions

39 amino acids

Exenatide

is used for type 2 diabetes treatment to improve glycemic control and modestly reduce body weight through GLP-1–like insulinotropic and glucagonostatic effects

amino acids

Dulaglutide

is a once-weekly GLP-1RA for type 2 diabetes that lowers HbA1c and body weight by enhancing glucose-dependent insulin secretion and reducing appetite

amino acids

Setmelanotide

is approved for chronic weight management in patients with POMC, PCSK1, LEPR deficiencies and Bardet–Biedl syndrome by reducing hunger and promoting weight loss

10 amino acids

Kisspeptin

is a key regulator of the hypothalamic–pituitary–gonadal axis, controlling puberty and fertility; kisspeptin-10 also inhibits trophoblast invasion and tumor metastasis in experimental models

13 amino acids

Melanotan I

is approved in some regions for prevention of phototoxicity in erythropoietic protoporphyria and is studied as a skin-darkening, photoprotective peptide

7 amino acids

Melanotan II

is studied as a tanning and libido-enhancing agent; increases melanin production and can reduce food intake and modulate sexual arousal in animal models and humans
