Freedom Diagnostics, 2026-03-31
15 sellers, 23 listings, 4 vial sizes, read from each store's public product feed on 2026-09-30. A seller with a recent certificate from a named lab ranks above a cheaper one without. Every card says why it sits where it does. The price is the total for the vial. A blend is not priced per milligram of one peptide inside it.
No public certificate file we opened names DSIP with selank and epitalon in its address or in the sample note. That is a count of files, not a grade, and compounds are not ranked against one another. A seller-published certificate is not a blind test. Certificate search.
Some seller links may pay this site when you buy through them. A payment never changes a seller's tier or rank, and no seller has a say in any page.
Best value with a certificate: Luxe Peptides, $33.0 for 5 mg. Cheapest of all: Sports Technology Labs at $23.5 for the 5 mg vial, grade B. DSIP with selank and epitalon 5 mg vials, middle price $36.0 across 13 sellers.
