Testing: Labs & Certificates of Analysis

Arctic Lab Supply publishes a batch certificate library. On October 17, 2026 it listed 12 lot-matched reports for 11 products, one per product, strength and lot, and each row linked the issuing laboratory's own verification page. The vendor states that reports stay published after a batch sells out.

As the vendor publishes them, five reports dated October 15, 2026 come from Freedom Diagnostics (tesamorelin, BPC-157 10 mg, GHK-Cu 100 mg, KLOW and a second report on one retatrutide lot), each stating purity by HPLC, identity by mass spectrometry (LC-MS) and a passing endotoxin test (USP <85>). The others come from ILS Laboratories, dated August 2026, and state purity by HPLC. Older reports from Janoshik are kept in the library as images.

Prof. Peptide drew three certificates, two from ILS Laboratories (GHK-Cu 50 mg and retatrutide 10 mg) and one from Freedom Diagnostics (BPC-157 10 mg), and found each at the issuing laboratory's own lookup on October 17, 2026, issued to Arctic Lab Supply. The two ILS records add a PCR sterility screen, endotoxin and five heavy metals to purity, identity and net content.

All products are sold for laboratory research use only.
