Peptides for Fat Loss
Beginner peptide guide
Fat-loss peptides fall into two camps: GLP-1 style agonists that quiet appetite, and growth-hormone fragments that nudge fat metabolism. The GLP-1 family does most of the heavy lifting for weight loss, and all of them work best alongside protein and resistance training.

• GLP-1 agonists (semaglutide, tirzepatide, retatrutide) reduce appetite and are the most studied.
• GH fragments (AOD-9604, HGH Frag) are gentler and support fat metabolism rather than force it.
• Protein and lifting protect muscle while you lose fat, the peptides do not do that for you.
