About this test

This independent HPLC-UV/VIS lab test confirms Sermorelin 5mg from Certified Peptides at 99.48% purity with an actual assay of 4.90 mg. The analysis was performed by Vanguard Laboratory and reported on December 19, 2025, under Batch Number 250904SERM5.

Sermorelin is a synthetic analog of growth hormone-releasing hormone (GHRH) consisting of the first 29 amino acids, researched for its role in stimulating natural growth hormone production, improving sleep quality, and supporting body composition. Additional testing confirmed endotoxin levels below 0.05 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.
