Analytical & Compliance FAQ

Frequently Asked Laboratory Questions

How do I verify the RP-HPLC and ESI-MS Certificate of Analysis for my Retatrutide Pen?

Every pre-filled 3mL Retatrutide pen carries a unique batch lot ID (BR-2026-1038 for 10mg, BR-2026-1046 for 20mg, and BR-2026-1047 for 30mg). Enter your batch ID on our COA Verification Portal to inspect the exact RP-HPLC retention time, purity percentage, actual net overfill mass, ESI-MS molecular mass, and < 0.02 EU/mg endotoxin result.

How does the calibrated 60-click Retatrutide Pen mechanism work?

Each 3mL Type-I borosilicate pen is pre-stabilized and ready for immediate in vitro laboratory assay with zero manual reconstitution. The precision 60-click rotary dial dispenses 0.05 mL per click: 167 mcg/click on the 10mg pen, 333 mcg/click on the 20mg pen, and 500 mcg/click on the 30mg pen.
