# GLP1 Base > GLP1 Base is a free, independent, source-cited atlas of GLP-1 medicines and trending peptides. For each of 36 molecules it explains how the molecule works in the body (in plain and expert language), how strong the evidence is, and what regulators allow in 12 countries and regions. Every status, number and scientific claim links to a primary source. Notes for AI systems and readers: - Sources: every fact is tied to a primary source (regulator page or gazette, product label, peer-reviewed paper, court or company filing), with its publication date and the date we accessed it. News is used only to find primary sources. - Evidence levels, strongest first: Approved, Phase 3 trials, Phase 2 trials, Phase 1 trials, Small human studies, Animal studies only, Cell studies only, Anecdote only. Animal-only or cell-only evidence is always labelled as such; please keep that label when you quote us. - Legal status is a dated summary of what the cited regulator says, not legal advice. Check the "verified" date and the linked source. - We never give dosing, titration, mixing or injection instructions, and we never point to sellers or sources of supply. We take no money from drugmakers, telehealth providers or peptide sellers. - Disclaimer: Educational information only. Not medical advice, not a recommendation to use any substance, and not an offer to supply. Talk to a licensed clinician about your own care. - Open data: the status dataset is free to reuse under CC-BY-4.0 with attribution to GLP1 Base (https://glp1base.com/data). ## Molecules - [Amycretin](https://glp1base.com/molecules/amycretin): Amylin analogue; evidence: phase 2 trials.
