Retatrutide

Nothing goes on sale until an independent laboratory has checked it four ways. The certificate for the exact lot you receive is published on this page and in our lab results library.

• How pure it is. The sample is separated into everything it contains and the compound is measured as a percentage of the total. Method: HPLC.
• That it is the right compound. The molecule is weighed and matched against what this peptide should weigh. Method: mass spectrometry.
• No bacterial endotoxins. Fever-causing bacterial fragments that a purity test will never reveal. Method: LAL test.
• No heavy metals. Metal traces left behind by reagents, catalysts and equipment. Method: ICP-MS.

The lot number on the certificate matches the one printed on your vial.

This product is supplied as a lyophilised powder and must be reconstituted before use. Let the vial reach room temperature, wipe both septa with an alcohol pad, then add bacteriostatic water slowly down the inner wall of the vial rather than directly onto the cake. Peptides are shear sensitive.

Swirl gently until dissolved. Never shake. The solution should be clear and free of particulates.
