Vendors are ranked by independent third-party HPLC and Mass Spec testing. The default sort surfaces the lowest price per milligram first; you can toggle to sort by purity score or test volume. Boren Health does not accept payment to influence rankings.

$/mg is the price per milligram of peptide, calculated from the listed product price and the vial size. It's the most accurate way to compare costs across vendors that sell different vial sizes.

Prices are scraped from vendor websites continuously and refreshed every 24 hours. Each row shows when its price was last verified.

A purity score is the average HPLC purity percentage from all independent lab tests we've run on samples from a given vendor's FOXO4-DRI. A score of 10/10 means 100% purity. Most reputable research peptides score 8.5–9.5.

No. All peptides listed are sold for laboratory research purposes only and are not intended for human consumption or clinical use. Always consult your jurisdiction's regulations before purchasing.

When a vendor has scraped pricing but no lab tests on file yet, they're flagged as 'Not yet tested.' We're constantly expanding test coverage; vendors can submit samples or wait for our next sweep.
