Retatrutide (LY3437943)
Triple Receptor Agonist Protocol
An in-depth biochemical review of the first single-peptide triple agonist targeting the GLP-1, GIP, and Glucagon (GCG) receptors simultaneously. Verified at >99.9% HPLC purity by third-party analytical mass spectrometry.
1. The Triple Incretin Mechanism of Action
Unlike mono-agonists (e.g. Semaglutide, GLP-1R only) or dual-agonists (e.g. Tirzepatide, GLP-1R + GIPR), Retatrutide incorporates balanced agonism at three distinct metabolic target receptors:
Slows gastric emptying, modulates central hypothalamic satiety pathways, and inhibits inappropriate postprandial glucagon secretion.
Enhances insulin sensitivity in adipose tissue, buffers free fatty acid release, and attenuates GI adverse events associated with GLP-1 activation.
The critical differentiator: stimulates hepatic lipid oxidation, thermogenesis, and basal metabolic energy expenditure.
2. Pharmacological Comparison: Retatrutide vs. Dual & Mono Agonists
| Parameter | Retatrutide (LY3437943) | Tirzepatide | Semaglutide |
|---|---|---|---|
| Target Receptors | Triple (GLP-1, GIP, GCGR) | Dual (GLP-1, GIP) | Single (GLP-1) |
| Glucagon Activation | Yes (Full Agonist) | None | None |
| Mean Weight Reduction (Phase 2, 48w) | 24.2% (12mg arm) | 20.9% (SURMOUNT-1, 72w) | 14.9% (STEP-1, 68w) |
| Hepatic Steatosis Resolution | >80% liver fat reduction | ~40-50% reduction | ~30% reduction |
| Molecular Weight | 4,731.33 g/mol | 4,813.45 g/mol | 4,113.58 g/mol |
Active Cold-Chain Fulfillment Protocol
