Retatrutide, Tirzepatide, Semaglutide, Cagrilintide & Tesamorelin — the most effective peptides for weight management. HPLC-tested, ≥98.9% purity, discreetly delivered.
The most potent GLP-1 peptides
Scientifically sound, clinically proven — for maximum results in weight loss and metabolism.
Retatrutide
Triple agonist · GLP-1 / GIP / glucagon
As a next-generation triple agonist, retatrutide activates three receptors simultaneously and has shown the highest weight loss of all GLP-1 drugs in clinical trials to date.

Dual-agonist · GLP-1 / GIP
The dual GIP/GLP-1 agonist significantly outperforms pure GLP-1 drugs in studies. Known as the active ingredient behind Mounjaro® — with superior efficacy compared to semaglutide.
Semaglutide
GLP-1 agonist Ozempic® / Wegovy®
The most proven GLP-1 drug with extensive clinical data. Weekly half-life, strong cardiovascular benefits, and significant weight loss.
How GLP-1 peptides work
The science behind the most effective weight loss drugs.
Appetite suppression
GLP-1 peptides activate satiety centers in the hypothalamus — the feeling of hunger decreases, and calorie intake is significantly reduced.
Metabolism boost
Activation of GIP and glucagon receptors increases energy consumption and boosts fat burning.
Weight loss
The result: sustainable weight loss of up to 28.3 % — scientifically proven in the TRIUMPH Phase 3 study (May 2026).
