Every certificate we hold is open. Read one before you buy.
Three independent laboratories tested this catalogue. Their documents are published exactly as they arrived, on the product page, before you pay. Nothing behind a login.
Tested in the USAAccredited lab, Fort Lauderdale
Counted from the certificate records on 26 October 2026, not typed by hand. A purity figure is shown where the certificate states a measured one. Where it does not, this page shows a dash rather than an estimate.
Two labs. Neither one is ours.
We do not run assays and we do not issue certificates. Analysis is commissioned from independent laboratories, and their documents are published exactly as they arrive. An in-house result is a claim. A third-party result is evidence.
They are not equivalent on paper, and we are not going to average them into one comfortable sentence. Here is the difference, in the laboratories’ own words.
We could have shown you only the accredited ones. Here is all of it instead.

These documents print an accreditation statement, in these words: “testing was performed using validated methodologies and is accredited pursuant to ISO/IEC 17025:2017.”
One report can cover more than one fill. Where several sizes were filled from one batch, the same report is filed against each of them. The index below shows the same report number repeating down those rows. You can watch it happen rather than take our word for it.
Nothing here is re-typed. Each document below is the file as the laboratory issued it, published whole rather than summarised into a figure by us.
Six things to find on any certificate, from any supplier
Before you open ours, here is what to look for. Take this list to anyone you buy from.
-
The issuing laboratory
A named lab with its address and phone number in the letterhead. Most of ours are tested by ILS Laboratories in San Diego. A certificate that does not say who ran the test is not a certificate.
-
The compound, size and lot
Printed by the lab, not the seller: here Tesamorelin 10mg, lot ACE-1498675. Match that lot number to the one on your vial.
-
Purity against a specification
The measured figure beside the standard it has to meet. On this one, 99.74% by HPLC against a specification of at least 95.0%, marked pass.
-
Identity and real content
Identity confirmed by HPLC retention-time match, and the net peptide content actually measured in the vial: 10.51mg against a 10mg label.
-
Safety screens
Tests beyond purity, each with its limit printed: a fentanyl screen, and heavy metals by ICP-MS for arsenic, cadmium, chromium, mercury and lead.
-
A way to verify it
The dates the sample was received and analysed, plus a QR code and access code to check the report on the lab’s own site. If the lab cannot confirm it, treat it as unverified.

What buyers said

What we do not claim
Everything above is about documentation: what the material is, who measured it, and what they measured. None of it is a claim about what the material does.
