The single most important skill on this site is reading how strong the evidence is behind a claim. Because the peptide space is full of things said about compounds — and not all of it is backed equally.
We label every claim with an evidence tier so you can tell the difference at a glance:
- ✦Clinical — larger or rigorous human studies
- ✦Limited human — small studies or early trials
- ✦Preclinical — cell or animal studies only
- ✦Community — what forums and users report, anecdotal
- ✦Mixed — a blend across the page
The difference between "studied in rats" and "proven in people" is the difference between hope and a fact. Evidence tiers exist so you never confuse the two.
✦ Key takeaway
Hope lives low on the ladder; facts live high. Always check which rung a claim sits on.
