Testing: Labs & Certificates of Analysis
GhostLabz shows a batch history of certificates on each product page, with no account needed. The certificates are from ILS Laboratories (tested for GhostLabz, analysed June to October 2026) and list HPLC purity, net peptide content, identity by HPLC retention time and a fentanyl screen; each carries a COA number and an access code for ILS's lookup. One GL-3 RT report from March 2026 is from Freedom Diagnostics.
Mark of Prof. Peptide looked up six of GhostLabz's ILS certificates on ILS Laboratories' own verify page on November 7, 2026, and all six matched GhostLabz's copies, each reporting all tests passed and fentanyl not detected: three of BPC-157 10 mg, including two separate tests of lot BPC10-GL01 (June 27 and July 23, 2026), and three of GL-3 RT, 10 mg and 20 mg, whose identity rows confirm retatrutide. GhostLabz prints its own lot labels, so where its label differs from ILS's the certificate below shows the lot both ways. Those six certificates' results are below.
