CURATED VENDOR PROFILE
Prime Lab Peptides
A Miami-identified Shopify storefront whose GLP-1 line carries Freedom Diagnostics certificates that resolve independently at the issuing laboratory, attached to a broad openly priced catalog.

Prime Lab Peptides publishes certificates as product-gallery images rather than in a certificate library, and the strongest of them verify at Freedom Diagnostics under the Prime Lab client name. That verified evidence is concentrated on the GLP-1 range; most of the catalog carries vial photography only. PeptideBenchmark normalizes the full peptide range to $/mg, withholds listings the vendor marks unavailable, and separates independently confirmed certificates from named-lab reports that cannot currently be checked.
Readers focused on the GLP-1 range who want certificates that can be checked at the issuing laboratory rather than only viewed on the vendor’s own site.
Every product page carries a “COA AVAILABLE” badge, but certificates exist for only a minority of the catalog’s distinct compounds — the GLP-1 line. The remaining products display vial photography and no certificate of any kind, so the badge is not a per-product guarantee. Bulk ten-vial kits are the cheapest per-mg listings and are currently marked out of stock, so PB withholds them from the board rather than advertising a price that cannot be bought. The storefront also refuses non-browser traffic, so PB reads it with a real browser session rather than an ordinary crawler.
Product-gallery COAs with Freedom Diagnostics provider verification
Certificates are attached to product pages as gallery images with no distinguishing filename, so PeptideBenchmark identifies them by reading each image rather than by its name. Freedom Diagnostics certificates are confirmed against the laboratory’s own host under the Prime Lab client name and carry accession, lot, net peptide content and HPLC-UV purity. Janoshik test reports on the same surface state a task number, and 2 also print their unique key, but Janoshik answers automated checks with a managed challenge, so those remain named-lab evidence without a provider badge.

Assayed content is not fill accuracy. Laboratories report net peptide content, and peptides ship as salts, so an honestly filled vial commonly assays below its gross label — a figure under 100% is not evidence of a short vial. These numbers are also not comparable between vendors: they exist only where a laboratory reports net content, so they partly reflect which laboratory a vendor uses.
