About Retatrutide / Cagrilintide Blend
Multi-Compound BlendsEqual parts of a triple incretin agonist and an amylin analogue — 5 mg of each in a 10 mg vial, once weekly. The thing to understand before dosing it: the two components were trialled on very different scales. Retatrutide ran up to 12 mg weekly, cagrilintide only to 2.4 mg. Because a 1:1 blend moves both together, cagrilintide hits its ceiling at 4.8 mg total — and at that point retatrutide is still only at 2.4 mg, nowhere near its higher arms. Cagrilintide is what caps this blend, and pushing past it takes the amylin component beyond anything that has been tested.

Why an incretin is paired with an amylin analogue
10 mg vial- Retatrutide 5 mg
- Cagrilintide 5 mg
Two different appetite pathways. Retatrutide is a triple GIP/GLP-1/glucagon agonist; cagrilintide is a long-acting amylin analogue. Amylin and incretin signalling are separate systems, and combining them is an active area of clinical development — the cagrilintide plus semaglutide combination has been trialled in humans.
That said, this specific pairing has not. And retatrutide itself is not approved anywhere, so a blend containing it inherits every caveat on the retatrutide page.
