Lab Testing

Lab testing & reports.

Who tests our materials, what they check, and how to verify every report with the laboratory itself.

Two kinds of lab report

Lot verification is done by Freedom Diagnostics, an independent laboratory in the United States. It tests a sample from the exact lot we sell, confirms identity by LC-MS, and measures purity by HPLC-UV and the net content of the vial. The lot number on its report is the lot number printed on your vial.

Reference reports come from Janoshik, an independent laboratory in the Czech Republic. They test the manufacturer's batch, so they are an independent reference for the material, not a test of the exact lot on your vial. Each one says which batch it tested and how that batch relates to the lot we sell.

Check any report with the lab

We copy every result exactly as the laboratory reported it and never round or edit a value. Every report below includes what you need to look it up with the laboratory itself: a Janoshik task number and unique key, or a Freedom Diagnostics search code. Check it there, not here.

Verified before it can be ordered

A material can be ordered only once its current lot has been checked against a laboratory report. Materials still waiting for that check stay listed in the catalog, marked as awaiting lot verification. Verified, and ready once ordering opens: BPC-157 10 mg, GHK-Cu 100 mg, GLOW Blend 70 mg, Ipamorelin 10 mg, KLOW Blend 80 mg, RP-116 20 mg, Tesamorelin 10 mg.
