AICAR vs Retatrutide
Both are discussed for weight loss. What this site records about each, side by side. Every figure is on the compound's own page with the source it came from.
| AICAR | Retatrutide | |
|---|---|---|
| What it is | A nucleoside, not a peptide. About fifteen hundred people have been given it intravenously in a heart surgery trial, where it did nothing. Banned in sport since 2009 on the strength of a mouse study. | An investigational once-weekly triple agonist acting on the GLP-1, GIP and glucagon receptors. Not approved anywhere. |
| EvidenceHow much human evidence exists, not how well it works. | Early human trials | Early human trials |
| Regulatory statusReviewed 2026-09-01 | Not approved for any indication. Developed as acadesine and abandoned after a phase 3 trial was stopped for futility. Prohibited in sport at all times by WADA as an AMPK activator, and detectable. Material sold as a research chemical is not the clinical infusion product. | Investigational. Not approved for human use in any jurisdiction. Sold only as a research chemical, with no manufacturing standard behind that label. |

This page is educational. It describes what published research reports, not what you should do. Peptides discussed here are largely not approved for human use, and nothing on BioAlmanac is medical advice. Nothing here ranks these two against each other. A table can show that one has more human evidence behind it or costs less per milligram; neither of those is a recommendation, and the right comparison for any person is one their doctor makes with them.
