Amylin vs other weight loss peptides AOD 9604 (HGH fragment): Mechanism: Fat metabolism stimulation Weight loss: 5-8% (limited data) Completely different pathway than amylin Could theoretically combine Retatrutide (triple agonist GLP-1/GIP/glucagon): Mechanism: Three incretin pathways Weight loss: 20-25% in trials More powerful than tirzepatide Also investigational Different mechanism than amylin Growth hormone peptides (CJC-1295, Ipamorelin): Mechanism: GH release, body composition Weight loss: Minimal direct fat loss Primarily muscle preservation/growth Often combined with amylin or GLP-1 for body recomposition Amylin's unique position: Only peptide class targeting amylin pathway Strongest gastric emptying delay Proven synergy with GLP-1s Different mechanism than all other weight loss peptides See our peptide stacks guide , peptide stack calculator , and can you cycle different peptides
