Peptide Intelligence

15-AA synthetic peptide from human gastric juice protein. Strongest preclinical evidence for tissue healing: muscle, tendon, ligament, bone, gut, neuro. No RCTs yet.

Synthetic thymosin β4 fragment. Promotes angiogenesis, tissue repair, cell migration, reduces fibrosis. WADA banned. Popular in sports/bodybuilding.

43-AA endogenous peptide in most tissues. Promotes cell migration, angiogenesis, wound healing, anti-inflammatory. Not WADA banned. Engineered versions showing promise in diabetic wound healing.

FDA-approved for HSDD in premenopausal women. Works centrally (MC4R), not hormonally — unique mechanism vs PDE5 inhibitors or hormones.

Synthetic GHRH(1-29) with MPA modification. Stimulates pulsatile GH release. Often paired with Ipamorelin for synergistic effect. WADA banned.

Selective ghrelin mimetic. Stimulates GH release without affecting cortisol or appetite as much as other GHRPs. Often paired with CJC-1295. WADA banned.

FDA-approved GHRH analog for HIV-associated lipodystrophy. Stimulates endogenous GH, reduces visceral adipose tissue ~15%. Off-label aesthetic body contouring potential.

Mixture of neurotrophic peptides and amino acids. Approved in Europe/Asia for stroke, dementia, TBI. Crosses BBB. Not FDA-approved but available through specialty pharmacies.

Human plasma tripeptide (Gly-His-Lys) bound to copper 2+. Declines with age. Stimulates collagen, tightens skin, reduces wrinkles/fine lines, promotes wound healing. Topical and injectable forms.

FDA-approved GLP-1 receptor agonist for type 2 diabetes (Ozempic) and chronic weight management (Wegovy 2.4mg weekly). Mean 14.9-16.8% body weight loss in STEP trials.

First dual GIP/GLP-1 receptor agonist. Superior weight loss vs GLP-1 RAs alone. Up to 22.5% weight loss in SURMOUNT-1. Approved for T2DM (Mounjaro) and obesity (Zepbound).

28-AA peptide from thymosin fraction 5. Immune modulator. Approved in 30+ countries (not FDA-approved). Used for hepatitis B/C, immune support, cancer adjunct. Restores immune balance in liver failure.
