What is retatrutide? The triple agonist explained

Retatrutide is the most searched GLP-1 class compound on PeptideTech. What it is, how it is sold and what a 30 mg vial costs.

PWBy PeptideTech EditorsReviewed 2026-09-01Prices checked weeklyHow we verify →

Retatrutide is an investigational triple-agonist peptide acting on GLP-1, GIP and glucagon receptors, developed by Eli Lilly and studied in phase 3 obesity trials. Research vendors sell it as a lyophilized powder in 10–30 mg vials.

How it is sold

Research vendors list retatrutide in 10mg, 20mg, 30mg vials. Several vendors use catalogue names such as GLP-3R rather than the compound name; PeptideTech maps these aliases to one product page.

Price today

The cheapest in-stock retatrutide 30mg today is $75.00 at American Peptides after code TECH10. Prices are checked weekly.

Research-use status

Retatrutide is an investigational compound. It is sold for laboratory research only and is not approved for human use.

How we verify prices

Prices are read from each vendor's product page weekly, converted to the price after any listed code, and shown before shipping. Stock status is captured at the same time. Rankings are by price only. PeptideTech earns a commission when you buy through a link; it never changes the order.
