🔥 Popular Peptides
Semaglutide
99An FDA-approved GLP-1 receptor agonist used for type 2 diabetes and chronic weight management, producing significant weight loss of 15-17% body weight in clinical trials.
BPC-157
98A 15-amino acid synthetic peptide derived from human gastric juice that promotes healing of tendons, ligaments, muscles, gut lining, and other tissues through multiple regenerative pathways.
Tirzepatide
97A first-in-class dual GIP/GLP-1 receptor agonist that produces up to 22.5% body weight loss, approved for type 2 diabetes and obesity management.
Ipamorelin
92A highly selective growth hormone-releasing peptide (GHRP) that stimulates GH release with minimal impact on cortisol, prolactin, or appetite, making it the cleanest GHRP available.
MK-677 (Ibutamoren)
91An orally active, non-peptide growth hormone secretagogue that mimics ghrelin to raise GH and IGF-1 levels for up to 24 hours per dose, with notable effects on sleep, appetite, and body composition.
CJC-1295 (no DAC) / Mod GRF 1-29
90A modified growth hormone-releasing hormone fragment with a short half-life (~30 minutes) that stimulates pulsatile growth hormone release, closely mimicking the body's natural GH secretion pattern.
TB-500
89A synthetic version of the naturally occurring 43-amino acid peptide Thymosin Beta-4, widely used for tissue repair, wound healing, reduced inflammation, and improved flexibility.
CJC-1295 (with DAC)
88A long-acting growth hormone-releasing hormone (GHRH) analog with a Drug Affinity Complex that extends its half-life to 6-8 days, producing sustained elevated growth hormone and IGF-1 levels.
