What ships
Each vial holds lyophilized retatrutide under a rubber stopper and an aluminum crimp seal, labeled for research use only. A certificate of analysis for the lot ships with every order.
From fill to seal
How a vial is made: sterile solution is dosed in, freeze-dried into the lyophilized cake, stoppered and crimped, then labeled. Select a step to jump to it.
The 3D animation needs WebGL. The sequence is: fill, freeze-dry, seal, label.
One peptide, three receptors
Retatrutide is a triple agonist: it binds and activates three related class B GPCRs. Select a receptor to see what it is and where it is found.
