What does the
evidence say?
Find a name you've heard. Open the profile for its studies, limitations and access routes. A grade describes the record's evidence, not proof for every possible use.

The evidence system
What does
a grade mean?
Our published rubric classifies the evidence in each compound record. Always read the profile for the studied condition, formulation and limitations. Legal status is shown separately.

- Grade B
- Real human trials, limited or historical
- 6 records
- Grade C
- Early / foreign human data only
- 14 records
- Grade D
- Animal studies only, unproven in humans

FAQ
A few useful answers.
How do I find the best peptide for my goal?
Start with a goal above, then read the relevant compound profiles. Check whether the cited research studied your specific goal, which people were studied, and the limitations. A compound's overall evidence grade is a starting point, not proof that it works for every listed use. A licensed clinician can assess whether a treatment is appropriate for you.
Does an evidence grade tell me whether I can buy it?
No. Evidence and legal access answer different questions. We show a separate US status for each compound and link to access information where a route is documented. Being studied, advertised or listed in a directory does not establish that a product is legally available or suitable for you.
Can I compare peptides without choosing one?
Yes. Open Compare for side-by-side records and curated comparisons. You can inspect the evidence, legal status and limitations before deciding what to discuss with a clinician. Our calculators work on inputs you provide and do not recommend a treatment or dose.
