Retatrutide (LY3437943) is a next-generation triple-agonist peptide targeting GLP-1 receptor, GIP receptor, and glucagon receptor simultaneously — a broader mechanism than dual agonists (tirzepatide) or single agonists (semaglutide). Phase II trials demonstrated 24.2% mean body weight reduction at 48 weeks. These capsules (10mg per capsule, 30 capsules) provide an oral research format for metabolic signaling studies.
Retatrutide is studied in obesity, type 2 diabetes, NAFLD/NASH, and metabolic syndrome research. The oral capsule format complements injectable vial protocols for pharmacokinetic comparison studies. Compare with Retatrutide vials and Tirzepatide for dual vs. triple agonist comparisons.
For Research Use Only. Rainbow Peptide supplies this compound exclusively for in vitro and laboratory research purposes. Not for human or veterinary use.
Third-Party Verified
We don't just claim purity — we prove it. Every batch of Retatrutide Capsules (10mg) is independently tested by an accredited third-party laboratory before it reaches you. Your COA is linked to your specific lot number.

Third order now. Consistent batch-to-batch results matter enormously in long-term research. Certificate of Analysis is detailed with mass spec data. Would not switch sources.
Verified against our reference standards. Purity >98.2% by HPLC. Packaging was appropriate for temperature-sensitive peptides. Will re-order.
