Owsa Labs publishes a product-specific Janoshik report for retatrutide 30 mg (batch RT30/250116) and states third-party COAs are available for selected lots. I also found a public Janoshik report for retatrutide 20 mg, but it is a different batch/strength and should not be used as evidence for the 30 mg vial.

Supplied as a lyophilised powder across six vial sizes, every batch reaches ≥99% purity confirmed by HPLC, with a Certificate of Analysis available on request. Independent Certificates of Analysis, published for every lot we ship. The testing itself is carried out by internationally recognised accredited laboratories — Janoshik Analytical (Czech Republic) and Analiza Białek (Poland).
