About SelfAssay — Compound Insights
Shopping for supplements or peptides and wondering what the evidence actually says? Highlight any compound name on any page and SelfAssay shows you an instant evidence card:
- An effectiveness grade, computed from thousands of first-hand community reports, broken down by purpose (sleep, focus, recovery, and more)
- A separate safety grade based on reported side-effects
- The most-reported effects and side-effects for that compound
- One click through to the full SelfAssay dossier: cited studies, clinical trials, and community signal
How it works: select a compound name (for example "BPC-157" or "ashwagandha"), click the small SelfAssay pill that appears, and the card renders right there on the page. You can also click the toolbar icon and type a compound name.
The grades come from SelfAssay's continuously updated index of 540+ compounds, combining classified community reports with curated research data. Grades are decision support for your own research. They are not medical advice, and a dash simply means we do not have enough first-hand data yet - we never fill gaps with guesses.
