Both are 39-residue acylated peptides on a GIP-type backbone with a C20 fatty diacid, and both are sold here as lyophilised powder in boxes of ten. The differences a buyer sees are in the vial: tirzepatide is offered here in more strengths and reaches a larger vial, and it carries a formula and mass on its sheet while retatrutide’s identity is quoted on the batch certificate. Structurally, tirzepatide has Aib at positions 2 and 13 with the lipid on lysine 20; retatrutide has Aib at 2 and 20 with the lipid on lysine 17. Both elute late on reverse phase and both are handled the same way.
