Third-party tested, lot-matched, published

Seven products have a lot-matched report from an independent analytical laboratory — currently ILS Laboratories (San Diego, CA), with earlier published records from Janoshik — and we publish each report with the lot number and the certificate number. No in-house claims, no summary badges.

How the documentation works here

  1. Every vial carries a lot number printed on the label.
  2. Seven products have a lot-matched third-party report — identity confirmed by HPLC retention-time matching, purity by HPLC, net peptide content and a fentanyl screen, plus ICP-MS heavy metals on four of the seven — published in the batch documentation library with its certificate number.
  3. You check before you pay. Open the report from the product page, match the lot, then order. The tracking email links each item in your box back to its report.

Questions people ask before ordering

Third-party versus in-house testing: what is the difference?

In-house testing is the supplier grading its own work. Third-party testing is an independent laboratory issuing a report under its own certificate number, which can be checked with that laboratory.

Which tests are on the report?

Every published ILS Laboratories report states chromatographic purity (HPLC), identity by HPLC retention-time match against a reference standard, net peptide content and a fentanyl screen. Four of the seven (BPC-157 5mg, GHK-Cu 50mg, Retatrutide 10mg and 20mg) also include an ICP-MS heavy-metals panel (arsenic, cadmium, chromium, mercury, lead). None includes mass-spectrometry identity testing. The full panel for each lot is on its PDF. The method, column and conditions are stated on the report itself.

Can I verify the report is real?

Yes. Each report carries the issuing laboratory's certificate number. Our verification guide walks through checking it.

How current are the reports?

Every report is dated and names its lot. Match the lot number on your label to the report before you rely on it.
