About this test

This independent RP-HPLC lab test confirms Retatrutide 64.06mg from Instant Peptides at 99.882% purity. The analysis was conducted by Kovera Labs on March 18, 2026, using validated analytical methods including batch conformity testing across three vials.

Retatrutide is a triple GIP/GLP-1/GCG receptor agonist researched for metabolic regulation, weight management, and glycemic control. A purity level of 99.882% indicates exceptional product quality with minimal contamination. Endotoxin safety screening returned a PASS result (≤0.5 EU/mL), and heavy metal screening showed negative results for Lead, Cadmium, Arsenic, and Mercury. Microbial sterility screening showed no growth.

The sample appeared as a lyophilized powder in a black-capped vial with silver crimp. The full certificate of analysis (Report #: KVR-2026-E32D51) is available for download on this page.
