About this test

This independent HPLC-UV/VIS lab test confirms GLOW 70mg from Certified Peptides at >99.80% purity. The assay measured 67.30 mg of GHK-Cu, 12.10 mg of TB-500, and 9.02 mg of BPC-157 per vial. The analysis was performed by Vanguard Laboratory and reported on January 30, 2026, under Lot Number 251125GS703.

GLOW is a proprietary peptide blend combining GHK-Cu (a copper peptide researched for skin remodeling and collagen synthesis), TB-500 (Thymosin Beta-4, researched for tissue repair and anti-inflammatory effects), and BPC-157 (a pentadecapeptide researched for wound healing and gastrointestinal protection). Additional testing confirmed endotoxin levels below 5.00 EU/mg (LAL method), sterility with no growth detected (USP <71>), and non-detectable levels of heavy metals including chromium, arsenic, cadmium, lead, and mercury via ICP-MS.
