Retatrutide is one of the most talked-about peptides in the weight loss and longevity space. It is a long-acting triple agonist that targets GLP-1, GIP, and glucagon receptor pathways, which is why retatrutide is often discussed alongside semaglutide and tirzepatide, but with an added metabolic angle.
Most people looking at retatrutide are interested in body composition, appetite control, metabolic health, and long-term weight management research. The GLP-1 and GIP activity makes retatrutide relevant to the same modern incretin category as other popular weight loss peptides, while the glucagon receptor activity is part of what makes retatrutide especially interesting for energy expenditure and longevity-focused protocols.
Progression Peptides offers retatrutide in 10mg, 20mg, 30mg, and 60mg vial options so you can choose the size that fits your protocol. The lower-strength vials are useful for conservative starts or smaller research plans, while the larger retatrutide vials make more sense for longer protocols or higher total-use planning.
Each vial is supplied as lyophilized retatrutide powder for reconstitution with bacteriostatic water. Store retatrutide properly, mix gently, and keep the reconstituted solution refrigerated.
Reconstitution: Reconstitute with bacteriostatic water. Allow to dissolve gently without agitation. The solution should be clear.
Storage: Store at -20 degrees C in lyophilized form. Refrigerate reconstituted solution at 2-8 degrees C and use within 30 days.
For Research Purposes Only. Not for human consumption. Not for veterinary use. Sold strictly for in vitro and laboratory research applications.
