Lab Results
Every batch is independently third-party tested before it ships — and published here in full. No login, no exceptions.
Two independent labs — Janoshik + Testides
Every batch is verified twice. First it's assayed by Janoshik Analytical, a widely-recognised independent testing lab, before release. Then we send the same batch to Testides in Toronto for our own confirmatory HPLC and mass-spec testing — each certificate below links straight to the lab's portal, no login required. Batches still at Testides show their Janoshik result in the meantime.
Every batch, published
We don’t ask you to take a purity number on faith. Every batch is sent to an independent third-party lab and the full certificate is published here — single-peptide lots and pre-blended vials alike, at their actual measured HPLC purity. Any lot still at the lab carries a pending badge until its certificate is released, so you always see exactly where each batch stands.
Published results — July 2026 batch
4 of 12 samples are back from Testides. The three single-peptide lots each returned ≥99.6% HPLC purity; the BPC-157 + TB-500 blend returned 98.64% combined. The remaining eight are still in testing.

Retatrutide 20mg and 30mg — blind-tested at Janoshik
Both lots were independently assayed by Janoshik Analytical on a blind GLP-1 panel. They're now with Testides in Toronto for our own confirmatory HPLC, as with the lots further down this page.
What a blind test is, and why it is stronger proof than a standard assay
Both lots below were submitted to Janoshik as a common GLP-1 peptide blind test. The lab was given three candidate compounds — semaglutide, tirzepatide and retatrutide — and was not told which of the three the sample was. In both cases Janoshik identified the material as retatrutide from its own analysis.
That distinction matters. A standard assay starts from the label: the lab is told what the sample is supposed to be and reports whether it found it. A blind test cannot confirm a label it was never shown, so it rules out the most common weakness in a peptide certificate — a lab result that only echoes what the vial already claims. Here, identity was established independently of the labelling.
Each lot's Janoshik reference number is printed on its card below — #207689 for the 20 mg lot and #210575 for the 30 mg lot — alongside the assayed purity and net content.

Net content on both lots assayed above label weight — 24.51 mg against a 20 mg label and 34.20 mg against a 30 mg label, consistent with the 11.88 mg recorded for the Testides-verified 10 mg lot above. Net content is the assayed mass of peptide in the vial as reported by the laboratory.
Still in testing — manufacturer results
These lots are already independently assayed by Janoshik Analytical, the manufacturer's third-party lab. They're now with Testides in Toronto for our own confirmatory HPLC — each card below is replaced by a full Testides certificate the moment it is released.

What we test for
Every batch is screened on three independent measures before it's cleared to ship.
Identity
LC-MS/MS
Confirms the compound in the vial actually matches what's on the label.
Purity
HPLC-UV
Measures the exact purity percentage of the peptide — the headline number on every COA.
Endotoxin
LAL method
Screens for bacterial endotoxins, a key marker of contamination.
