Which should you choose? Here's what you need to know.
Cagrilintide works through amylin receptors with strong Phase 3 data (especially combined with semaglutide). AOD-9604 is a GH fragment that didn't prove effective in large human trials.
AOD-9604 is a synthetic GH fragment studied for fat metabolism. It has an excellent safety profile but its Phase IIb trial failed to show significant weight loss vs placebo.
Choose AOD-9604 if:
You want a mild, low-side-effect option focused on fat metabolism — though the evidence is weak.
Cagrilintide is a long-acting amylin analog with Phase 3 data. As part of CagriSema (with semaglutide), it achieved 20.4% weight loss with lower nausea rates than GLP-1-only options.
Choose Cagrilintide if:
You want a peptide with strong clinical data and a different mechanism from standard GLP-1 drugs.
Once you've decided which peptide fits your needs, here's how they compare on price and vendor options.
Our top-rated vendor for each, based on trust scores, purity testing, and price.
We re-check vendor prices continuously and score vendors on Finnrick blind-test results — samples bought anonymously and sent to a lab, not vendor claims. No vendor can pay to rank higher. See our full methodology.
