How we grade peptide evidence
6/24/2026
Every product on Resurgence carries an evidence grade. It's not a star rating or a marketing badge — it's a structured read of the published literature for that compound.
What goes into a grade
We compile two public sources for each peptide:
- PubMed citations (peer-reviewed studies)
- ClinicalTrials.gov records (registered human trials)
…and the regulatory picture (whether an FDA record exists). A reviewer then assigns one of: strong, moderate, limited, insufficient, or ungraded.
Honest by design
If a compound has no indexed human trials, we say so — plainly. A thin evidence base produces a low grade, and the product page shows a "No human studies indexed" note rather than implying efficacy.
For research purposes only. Not intended for human consumption.
