Test results
About this test
This independent HPLC-UV-MS lab test confirms the Glow blend from Pure Peptides at 99.98% overall purity. The analysis was conducted by MZ Biolabs on March 12, 2026, with measured quantities of GHK-Cu 61.22 mg, BPC-157 13.51 mg, and Thymosin Beta-4 10.02 mg per vial (84.75 mg total).
The Glow blend combines three research peptides: GHK-Cu for tissue repair and collagen synthesis, BPC-157 for gastrointestinal and tissue health, and Thymosin Beta-4 for immune support and cellular regeneration. A purity level of 99.98% indicates exceptional synthesis quality and minimal contamination across all three compounds. The report notes that slight GHK-Cu complex dissociation during HPLC is normal.
