Retatrutide 20mg

Sign in for priceIn stock

Retatrutide is a GGG tri-agonist research peptide that works at all incretin receptors including GLP-1, GIP, and the glucagon receptor itself. It enhances glucagon production, leading to the breakdown of stored fats and glycogen, thereby increasing basal metabolism. Its actions on GLP-1 and GIP receptors promote delayed gastric emptying and appetite control, offering a comprehensive approach to obesity research distinct from older GLP-1 agonists.

About Retatrutide 20mg

Retatrutide is a new entrant into the rapidly expanding space of anti-obesity peptides. As a fatty acid acylated single peptide combining GCGR, GIPR, and GLP-1R activities based on a heavily modified GIP backbone, retatrutide binds to albumin in the bloodstream for a prolonged half-life requiring only once-weekly administration. In the Phase 2 obesity trial reported by Jastreboff and colleagues in 2023, participants on the highest dose of the investigational drug product had a mean body-weight reduction of about 24 percent at 48 weeks. That result describes a drug product given to human participants under a protocol and is not a statement about material supplied for laboratory research. This vial holds 20 mg of lyophilized powder and is released to a >99% purity specification by HPLC.

Storage and reconstitution

Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Shipping within Canada

Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
