Background
Retatrutide (development code LY3437943) is a 39-residue synthetic peptide developed by Eli Lilly. Its sequence includes the non-natural amino acids α-aminoisobutyric acid (Aib) and α-methyl-leucine, and one lysine carries a C20 fatty diacid attached through a linker, which accounts for its high molecular weight. F-RGLP-3 is the Flying Monkey Labs catalog code for this compound.
Storage and handling
Store sealed vials at −20 °C, protected from light and moisture. Let a vial reach room temperature before opening so condensation doesn't form on the powder. Use standard laboratory PPE and dispose of material as chemical waste under local rules.
