Best Selling Retatrutide Raw Peptide CAS 2381089-83-2 >99% HPLC Tested Raw Material In Stock With COA

What is Retatrutide？

Retatrutide (LY‑3437943) is a synthetic long‑chain acylated triple‑receptor agonist peptide targeting GLP‑1R, GIPR and GCGR. It is applied in pre‑clinical lab studies for receptor‑binding mechanism research, intracellular signal pathway exploration, animal‑model metabolic pharmacology experiments, peptide structure‑activity relationship evaluation and tri‑target candidate drug preliminary assessment.

Our Retatrutide is white lyophilized powder. Each batch undergoes strict HPLC and mass spectrometry testing to ensure purity above 99%. Relevant test documents can be provided upon customer request.

1. Delay gastric emptying, enhance satiety and suppress appetite;

2. Promote insulin secretion, inhibit glucagon release and regulate blood glucose;

3. Boost energy expenditure and regulate hepatic glucose‑lipid metabolism;

4. It demonstrates potent weight‑loss effects in clinical trials, reduces visceral fat, and improves insulin resistance, glycated hemoglobin and blood‑lipid indicators.

Packaging

Inner package adopts medical glass vials sealed tightly with rubber stopper and aluminium cap, each vial marked with batch info. Vials are fixed in shockproof foam tray to avoid breakage, then packed into thick cartons equipped with desiccants to prevent dampness. Neutral packaging and custom specification such as 5mg/15mg per vial are supported.

Delivery

In‑stock goods will be dispatched within 3‑5 working days after confirmation. Temperature‑sensitive lyophilized peptides will be shipped with ice packs cold chain to keep stable quality during transit. We offer multiple logistics options including international express, air freight and sea freight according to order volume. Tracking information and customs documents will be supplied after shipment.
