Retatrutide, also known by the development code LY3437943, is a synthetic 39-residue peptide engineered with non-coded amino acids and a C20 fatty diacid side chain. It remains an investigational compound and is not approved for any human or veterinary use. This product is supplied in a sealed vial as a lyophilized powder for use by qualified researchers in controlled laboratory settings.
Research background
Published pharmacology describes retatrutide as a single molecule with agonist activity at three receptors: the glucose-dependent insulinotropic polypeptide receptor (GIPR), the glucagon-like peptide-1 receptor (GLP-1R) and the glucagon receptor (GCGR). In vitro, it is used as a tool compound in receptor binding and signaling studies. These references are provided as scientific background only and do not describe any intended use of this product.
Lot verification
Each vial of Retatrutide carries a lot number linked to its own LIV MORE test results. See the Specification tab for compound data and the Test Results page for batch results.

Lyophilized storage
- Store unopened vials at -20°C or below for long-term storage. Short-term storage at 2 to 8°C is acceptable.
- Keep vials sealed, dry and protected from light.
- Lyophilized material is stable at ambient temperature for the duration of normal transit.
Handling on arrival
- Transfer vials to cold storage as soon as possible after delivery.
- Allow the vial to reach room temperature before opening to limit condensation.
- Handle using standard laboratory PPE in an appropriately equipped facility, following good laboratory practice.
Stock solution preparation
- For analytical work, stock solutions are typically prepared at 1 mg/mL in sterile water or a suitable buffer, following your own validated method.
- For a 20 mg vial, adding 20 mL of solvent gives a 1 mg/mL stock.
- Aliquot stock solutions and store at -20°C. Avoid repeated freeze-thaw cycles.
Disposal
- Dispose of unused material and empty vials in line with local regulations for laboratory chemical waste.
No dosing or administration guidance is provided. This material is for in vitro laboratory research only.
How do I view the Certificate of Analysis for my vial?
Every vial is printed with a lot number. Enter it on the Test Results page to open its test results, which show the purity result, identity confirmation, test date and the full certificate to view or download.
Why is a purity figure not listed on the product page?
Purity is batch specific, so it is reported on the Certificate of Analysis for each individual lot rather than as a general claim. The test results for your lot number show the result for the exact material you received.
How is Retatrutide shipped?
Vials are shipped as lyophilized powder in sealed glass vials, packed to protect against breakage. Lyophilized material is stable at ambient temperature during normal transit. Tracking details are sent once your order is dispatched. Orders placed before 11:00 am PST on a business day are dispatched the same day. Shipping to United States addresses is $5.99, or free on orders of $149 or more.
