What Retatrutide is
An investigational once-weekly triple receptor agonist producing the largest pharmacological weight loss reported to date in trials.
Retatrutide is an investigational triple agonist targeting the GLP-1, GIP, and glucagon receptors. Phase 2 trials reported up to ~24% body weight reduction at the highest dose.
Mechanism: Agonizes GLP-1, GIP, and glucagon receptors. The added glucagon activity increases energy expenditure and hepatic fat oxidation, complementing the appetite and insulin effects of the incretin receptors.
Regulatory history: Investigational, not FDA-approved; Phase 3 TRIUMPH-1 reported May 2026; submission expected late 2026
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Retatrutide at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
