MZ Biolabs, 2026-01-20
8 sellers, 8 listings, 2 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.
1 public certificate file we opened name Argireline. 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: Gila Peptides, $17.5 for 5 mg, $3.50 per mg. Argireline 5 mg middle price is $4.75 per mg across 2 sellers.

The figure is the same ungated market median the range on this page uses: every seller found. Certificate tier still ranks the cards. The purity gate is written and off, so this is not a tested-sellers-only series.
We never charge for knowledge. No vendor has a say in what a page says. Sellers are ranked by the certificate they publish, then by price. Every seller, graded · Laboratories named · How this is counted
