Popular Peptides
Orforglipron
Orforglipron (LY3502970) is a non-peptide, oral GLP-1 receptor agonist developed by Eli Lilly. Unlike oral semaglutide (which is a peptide requiring special formulation), orforglipron is a small molecule — the first of a new class of oral GLP-1 drugs that can be taken without fasting restrictions. It is in Phase 3 trials for obesity and type 2 diabetes, with an FDA decision expected in 2026. Projected to reach $16 billion in annual sales by 2031.
Learn moreMelanotan II
Melanotan II is a synthetic peptide analog of α-MSH with broader receptor activity than Melanotan I. It produces tanning effects and has notable effects on sexual function and appetite suppression.
Learn moreBPC-157
Body Protection Compound-157 is a synthetic peptide derived from a protein found in human gastric juice. It has shown remarkable healing properties in research studies.
Learn moreHumanin
Humanin is a mitochondrial-derived peptide with potent cytoprotective effects. Discovered in 2001, it has shown promise in protecting against age-related diseases including Alzheimer's, cardiovascular disease, and diabetes.
Learn moreIGF-1 LR3
IGF-1 LR3 (Long R3 Insulin-like Growth Factor-1) is a modified version of IGF-1 with extended half-life and enhanced potency. The modifications prevent binding to IGF binding proteins, increasing bioavailability.
Learn moreP21
P21 is a synthetic peptide derived from Cerebrolysin, specifically designed to mimic the neurotrophic effects of the parent compound. It promotes neurogenesis and has shown cognitive-enhancing properties in research.
Learn moreNA-Semax Amidate
NA-Semax Amidate (N-Acetyl Semax Amidate) is a modified version of Semax with enhanced stability and potency. Also known as NASA, it provides stronger and longer-lasting nootropic effects than standard Semax.
Learn moreSNAP-8
SNAP-8 (Acetyl Octapeptide-3) is a cosmetic peptide that reduces the appearance of wrinkles by modulating muscle contraction. It is often called 'topical Botox' though it works through a different mechanism.
