Retatrutide (LY3437943) is a long-acting triple receptor agonist synthetic polypeptide. It can simultaneously activate three important metabolic receptors: GLP-1R, GIPR and GCGR.

Compared with single or dual-target GLP-1 peptides, it has stronger regulating effect on glucose metabolism, fat decomposition and energy balance.

In preclinical scientific research, it is mainly applied in research projects related to type 2 diabetes mellitus, obesity, metabolic syndrome, hepatic lipid metabolism and appetite regulation.

1. How to place an order?

Please leave me a message with the specifications and quantity you need, and I will calculate the price for you.

2. What are the delivery time and shipping methods?

After receiving your payment, we will ship the package to you via USPS, FedEx, DHL Parcel, or Yanwen Express. Delivery takes approximately 7-15 days.

3. How to store the peptides after receiving them?

Lyophilized powder peptides can be transported at room temperature in vacuum packaging, while soluble peptides need to be refrigerated at 2°C - 8°C. For long-term storage, lyophilized powder peptides should be stored in a sealed container with desiccant and kept at a low temperature of -20°C or -80°C to minimize peptide degradation.

4. What payment methods are available?

We accept PayPal, bank transfer, WISE, and Bitcoin payments.
