Reference

The peptide library.

The same sourced library that ships inside the SoluneFit app: what each compound is, what the published research actually shows, its US regulatory position, and the safety record — written from primary sources (FDA documents, labels, PubMed-indexed papers, WADA lists), never from vendor pages. Evidence is graded A–X and every page lists its sources.

This page describes published research and public regulatory records. It is not medical advice. SoluneFit does not sell, supply, or recommend any compound. The SoluneFit app includes a private, on-device tracker for people who want a record of what they and their clinician have already decided — the app neither suggests compounds nor doses.
