Buying

How do you tell which research peptide vendors are legit?

A legitimate research peptide vendor publishes an independent laboratory certificate for every lot, and you can confirm that certificate with the laboratory itself. Luvaminos meets each of the seven checks below, and you can run all seven on any other store with its public pages. Check the lot on the vial against the certificate before you trust the rest.

What are the seven checks?

Each check can be answered from public pages in a few minutes, without contacting the seller. A store that fails the first two is not worth the rest.

How do you confirm a certificate is real?

Most independent laboratories print an accession or verification number on each report and run a lookup page of their own. Entering that number on the laboratory's site shows whether the lab issued the report, which the seller does not control. Compare the compound, the lot, the test date and the figures with the certificate you were shown.

What are the common red flags?

  • A purity percentage with no lot number, no laboratory name or no test date.
  • One sample certificate shown for a whole catalogue.
  • A laboratory that shares an owner or address with the seller.
  • Purity by HPLC only, with no identity test and no net peptide content.
  • No company name, no street address or no written refund policy.

What does research use only mean for a buyer?

Luvaminos supplies compounds for laboratory and in vitro research only, to buyers aged 21 and over, and nothing on this site is medical advice. A vendor that describes its products for use in people is making a claim it cannot document, which is a reason to leave.

Questions

It publishes an independent laboratory certificate for every lot, names the laboratory, prints the lot on the vial and lets you confirm the report with the laboratory. Luvaminos does all four.

At luvaminos.com/coa followed by the lot number printed on the vial. The all-certificates page at luvaminos.com/coa lists every lot.
