What is Retatrutide?

Retatrutide (LY3437943) is a synthetic single-chain peptide engineered from the GIP sequence with a lipidated side chain. In the research literature it is described as a triple agonist, meaning it is studied for its activity at three receptors at once: GIP, GLP-1 and glucagon. It is a newer compound than tirzepatide and appears in a rapidly growing body of published metabolic-signalling work. Regenwell PH supplies it as a research-grade lyophilised powder for in-vitro and laboratory study.

Purity and testing

Regenwell PH sends batches for independent third-party analysis and publishes certificates on the Certificate of Analysis page, hosted on the testing platform so they can be checked without an account. If a certificate for the current retatrutide batch is not yet listed there, message us with your order number and we will send it. We publish COAs because purity verification is the single most important check when choosing a peptide source in the Philippines.

Storage and handling

Store lyophilised vials in a cool, dry place away from direct light; for storage beyond three months, keep frozen at -20°C. After reconstitution with bacteriostatic water, refrigerate at 2 to 8°C and avoid repeated freeze-thaw cycles. Our storage guide and reconstitution and concentration reference cover laboratory handling in more detail.

Frequently asked questions

How is retatrutide different from tirzepatide as a research compound?

Tirzepatide is studied as a dual GIP/GLP-1 receptor agonist; retatrutide adds glucagon-receptor activity and is classified as a triple agonist. Retatrutide is also the newer of the two, so the published literature is smaller. Our comparison guide covers the differences in research context.

Is this a pharmaceutical product?

No. Retatrutide is an investigational compound and is not an approved medicine anywhere. Regenwell PH supplies a research-grade lyophilised peptide strictly for laboratory and educational study, not for human or animal use.

What is included in the Complete Set?

The retatrutide vial, a vial of bacteriostatic water and syringes. The Vial + BAC Water option omits the syringes; the Kit contains ten vials.

Which is the cheapest way to order?

Per vial, the 10-vial Kit is the lowest price and ships free. For a first order the 10 mg Complete Set at ₱1,920 is the lowest-cost complete option.

Do you ship outside the Philippines?

Our pricing and delivery times above are for the Philippines. For addresses outside the Philippines only the 10-vial Kit format is offered, and the price shown at checkout in your market applies. Contact us before ordering internationally.
