Melatonin prices

5 sellers, 5 listings, 1 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.

No public certificate file we opened names Melatonin 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.

Vial

Best value with a certificate: Peptide Labs, $65.0 for 10 mg, $6.50 per mg. Cheapest of all: Enhanced Peptides at $4.50 per mg for 10 mg, grade B. Melatonin 10 mg middle price is $6.00 per mg across 5 sellers.

5 of 5 listings at 10 mg, sorted grade first, then price per mg.

Week by week

Melatonin was first read on 2026-09-30. Middle price $6.00 per milligram across 5 sellers. A week-by-week line appears after the next finished weekly walk. One week is a snapshot, not a history.

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.

How the ranking works

LC
Lab-confirmed: the issuing laboratory echoed this certificate back
A
Current certificate, independent laboratory named, laboratory not yet checked
B
Certificate published, but no laboratory link, older than a year, or the laboratory did not recognise the published lookup
C
No certificate could be read
  • Grade first, then price per milligram within the grade. A cheap vial that is not the real compound is not cheap, so no price moves a seller above a better certificate. Sort by price if you want price alone. The grade stays on the card.
  • The grade is what we could read on the seller's site on the date shown, not what the seller claims. If a login page or a robot block hid the certificates, the card says so. A later check in a normal browser may raise that grade.
  • Prices are list prices before any discount code, shipping, tax or customs. Multi-vial packs are counted at their total milligrams, and their per mg price reflects that.
  • The dot on each card shows where that price sits between the cheapest and the priciest seller of the same vial. The tick is the middle price. A bigger vial's lower price per mg is never mistaken for a better seller.
  • Every seller links to its own page: the company behind it, address, store platform, labs named, a sample certificate, shipping and payment terms, and every warning sign we found.

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
