How It Works
Ship one vial to our facility in Texas, safely packed in a padded envelope, and we will test it at a commercial lab.

We will not return the sample, as it gets consumed in the analysis.
No vial to spare? No problem: suggest a product or vendor on Reddit instead.
What You Get
You will receive a copy of the certificate of analysis before it gets published here on the PeptideScore web site.
What We Test
PeptideScore accepts most common, single peptides, in lyophilized powder form.
For now we don't accept peptide blends, or other form factors:
- × Tablets, capsules
- × Sprays, liquids, or gels
- × Reconstituted peptides
We currently only accept shipments from the USA. 🇺🇸
