# SelfAssay > SelfAssay is a personal pharmacology lab: research any supplement, peptide, or longevity compound, grade it on what works and what's safe, and measure whether it's actually working for you. Every claim is cited to its source (real-world reports, peer-reviewed literature, and a curated knowledge graph), every cohort is sized, and the system refuses rather than fabricates when evidence is thin. Decision support, not medical advice. ## Core pages - [Home](https://selfassay.com/): What SelfAssay is and how it works. - [Grade My Stack](https://selfassay.com/grade): Free, grounded grade of a supplement/peptide stack across effectiveness, safety, synergy, and evidence. - [Privacy](https://selfassay.com/privacy): How data is collected, encrypted, used, and deleted. Member-owned Vault, opt-in cohort contributions. - [Terms](https://selfassay.com/terms): Terms of service. A personal-research and decision-support tool, not medical advice. ## Compound dossiers Per-compound dossiers live at `https://selfassay.com/` (for example `https://selfassay.com/bpc-157`). Each grades effectiveness and safety, summarizes most-reported effects and side effects from first-hand reports, and links published studies and clinical biomarkers to their PubMed sources.

It is not medical advice and is not a substitute for a clinician.
