Retatrutide is an investigational compound and is not FDA approved
This fatty acid chain binds non-covalently to serum albumin in the bloodstream, which: Protects the peptide from enzymatic degradation Creates a circulating reservoir the drug slowly releases from albumin into the free (active) form Slows renal clearance the albumin-drug complex is too large for kidney filtration Provides sustained release free retatrutide is continuously replenished from the albumin-bound pool DPP-4 Resistance An alpha-amino isobutyric acid (Aib) residue at position 2 makes retatrutide resistant to cleavage by the DPP-4 enzyme, which would otherwise degrade it within minutes
Reconstituted retatrutide must not be frozen unless this is explicitly validated and specified by the trial sponsor or manufacturer
