Retatrutide (LY3437943) is a novel triple agonist peptide targeting three key metabolic receptors simultaneously: GLP-1, GIP, and glucagon. This triple mechanism represents the cutting edge of GLP-based metabolic research, going beyond single & dual agonists like semaglutide (Ozempic) and tirzepatide (Mounjaro) to engage an additional metabolic pathway.
Originally developed by Eli Lilly, retatrutide has generated enormous research interest globally, with Phase 3 clinical trials (the TRIUMPH program) currently ongoing.
Each receptor contributes distinct metabolic effects, making retatrutide uniquely versatile for research applications:
| Receptor | Primary Effects | Retatrutide Activity |
|---|---|---|
| GLP-1 | Glucose regulation, appetite, gastric emptying | Full agonist |
| GIP | Insulin secretion, fat metabolism, bone health | Full agonist |
| Glucagon | Energy expenditure, lipid oxidation, hepatic metabolism | Partial agonist |
The addition of glucagon receptor activity distinguishes retatrutide from semaglutide and tirzepatide, enhancing energy expenditure and metabolic activity.
Retatrutide is being studied for its potential effects on:

Ordering was easy. Everything looks legit, delivery was 5 days, but i live in rural town in SA. Looking forward to see what this can do for me. Will buy from RCA again. Make sure you have done your own research as it comes with no info or instructions on how to use or reconstitute.
