Retatrutide (15mg)

Retatrutide, also called Reta, is a synthetic peptide with activity at GLP-1, GIP and glucagon receptors. This listing is for a 15mg lyophilised vial for in-vitro laboratory research. Milligrams describe the amount in the vial, not a dose or solution concentration.

The 15mg vial supplies 5mg more Retatrutide than the 10mg vial and 5mg less than the 20mg vial. Choose the quantity required by your laboratory work and compare the current listed prices. Vial content does not specify concentration or a treatment duration.

Retatrutide is commonly shortened to Reta or Reta peptide. LY3437943 is its research identifier. Check the compound name and milligrams per vial when comparing listings.

The 2023 Phase 2 obesity study compared Retatrutide with placebo. It does not validate this 15mg research vial or establish superiority to semaglutide or tirzepatide. See the Retatrutide 10mg research overview for the study population and evidence limits.

Retatrutide activates GLP-1, GIP and glucagon receptors. This triple-receptor profile is studied in metabolic signalling research. Receptor activity alone does not establish a clinical benefit or a safe human-use protocol. See the original receptor research.

Semaglutide targets GLP-1 receptors; tirzepatide targets GIP and GLP-1; Retatrutide adds glucagon-receptor activity. These are different compounds. The 2023 Retatrutide obesity trial used placebo as its comparator, so its results do not establish superiority over the other two medicines.

Retatrutide is supplied as a lyophilized powder and should be reconstituted with bacteriostatic water (BAC water) immediately before use. Inject the BAC water slowly into the vial, directing the stream down the inside wall. Gently swirl to dissolve — do not shake. Once reconstituted, store at 2–8°C and use within 8–12 weeks. For a general peptide reconstitution overview see our complete peptide reconstitution guide.

Store lyophilized Retatrutide vials at -20°C, away from light and moisture. After reconstitution, refrigerate at 2–8°C and use within 8–12 weeks. Do not freeze reconstituted solution.
