An editorially independent comparison platform that scores and ranks peptide vendors.
The peptide market hides prices behind login walls and ranks vendors on affiliate budgets. We rank on facts.
Make the peptide market comparable on facts.
Pricing, COA quality, US shipping, and payment variety are the things that actually separate a good vendor from a bad one. We score all of them on the same rubric: same questions, same weights, every vendor, every week, and we publish the math.
What we do
Normalized prices
Real $/mg you can compare across every vendor, including vial sizes and bundle math.
Lab transparency
Named third-party labs on every vendor. Independent Finnrick blind-buy grades on top vendors.
An objective 0 to 10 score
Same six-dimension rubric for every vendor. No favorites, no manual boosts.
A current directory
Vendor and peptide pages with last-checked dates, refreshed weekly.
How we score
Every vendor gets a 0 to 10 PR Score from six weighted dimensions:
Top vendors also carry a Finnrick blind-buy grade (A to E): an independent lab buys the product anonymously and tests it, so the vendor can't cherry-pick the sample.
PR Score is the weighted average of all six dimensions. A 9.5 on price but 4.0 on COA does not get a free pass. The math runs the same for everyone. Scoring 74 vendors today.
Our independence
We use affiliate links. When you buy through some of our vendor links we may earn a commission, and that is what keeps the site free.
Vendors cannot pay for rankings, placement, or a better score. Affiliate relationships have zero effect on the 0 to 10 score.
Updated weekly
Prices and stock re-checked weekly, with a last-checked date on each vendor.
For research only
Not FDA-approved for human consumption. We don't sell peptides or give medical advice.
Editorially independent.
We hold no advisor seats and no equity in any vendor, and no vendor can pay for a better score or placement. We may earn affiliate commissions on some links, but that money never affects our scores. We stay anonymous so we can publish unflattering findings without industry pressure.
