The label "peptide" covers a huge range — from rigorously studied, FDA-approved drugs to compounds sold online as "research chemicals" that have barely been tested in humans. Most marketing treats them all the same. They aren't.
This site's whole job is to tell you, compound by compound, what the human evidence actually shows — graded the same way every time, with the sources to check it. Why this exists →
The Codex Scale · 1–10
Every one of 100 compounds graded the same way.
One ten-point scale, applied without exception — from 10 · Established down to 1 · Unsupported. Here's where the field actually sits today.
- Peptides 101 What they actually are, and how to think about them.
- Are peptides legal? The honest U.S. status in 2026, in plain terms.
- "Research use only," explained What that label really means — and what it doesn't.
- Side effects & safety What's expected, what's a red flag, and when to stop.
- How we grade the evidence The exact scale we hold every compound to.
