Retatrutide in Vietnam: price, delivery and lab report

Retatrutide is no longer on Peptara Labs’ Vietnam price table: the store quotes it by message, so this page shows no price.

Janoshik report #195512 gives 4.070 EU/Vial for lot RETA-260512-A, analysed 30 June 2026, and Peptara Labs printed its key, 5BLXPQRZU4SH, for janoshik.com/verify. A certificate shows what one lot tested as; it does not show a product is safe or approved for use in people.

Research record

What retatrutide is, on the record

A compound in phase 3 development, described here by its registration record and study types only.

What it is

Retatrutide, development code LY3437943, is a synthetic peptide that activates the GIP, GLP-1 and glucagon receptors. It is in development for obesity and type 2 diabetes, and Eli Lilly and Company is the lead sponsor on its registered studies.

Sources: PubMed 35985340, ClinicalTrials.gov NCT06354660

Approval status

Retatrutide has no approved use, and phase 3 trials are underway. Thirty-three registered studies matched the compound when the register was read on 1 September 2026, and Peptara Labs sells it as research-grade material.

Sources: PubMed 41090431, ClinicalTrials.gov register

Evidence on the record

The strongest evidence on the record is phase 2 randomized, placebo-controlled trials, one in adults with obesity and one in adults with type 2 diabetes. We report no results from either and give no guidance on use.
