Retatrutide and Survodutide are both Metabolic peptides, but they're studied for different things. In short, Retatrutide is an investigational triple GIP/GLP-1/glucagon agonist studied for weight loss, while Survodutide is an investigational GLP-1/glucagon dual agonist studied for weight and liver health. This page compares the two side by side — what each is researched for, how mature the evidence is, and how they're typically used — so you can see where they overlap and where they differ. It's educational information only, not medical advice, and neither is a substitute for a conversation with a licensed professional.

How does Retatrutide work?
Retatrutide is an investigational "triple agonist" that simultaneously activates the GIP, GLP-1, and glucagon receptors. Adding glucagon-receptor activity is thought to increase energy expenditure on top of the appetite and glycemic effects of GIP/GLP-1, and early trials have shown substantial weight reduction.
How does Survodutide work?
Survodutide is an investigational dual agonist of the GLP-1 and glucagon receptors. Combining appetite regulation with glucagon-driven energy expenditure, it is under study for obesity and for metabolic-associated fatty liver disease (MASH).
Retatrutide vs Survodutide: how to choose
Choosing between Retatrutide and Survodutide really comes down to your specific goal — and it's a decision for you and a licensed professional, not something to settle from a web page. Retatrutide is most associated with Weight management and Blood sugar regulation, while Survodutide leans toward Weight management and Liver health (MASH). Where they overlap, the practical differences are usually in mechanism and how far the research has actually progressed.

Frequently asked questions
Both are Metabolic peptides. Retatrutide is an investigational triple GIP/GLP-1/glucagon agonist studied for weight loss; Survodutide is an investigational GLP-1/glucagon dual agonist studied for weight and liver health. They're most researched for Weight management, Blood sugar regulation (Retatrutide) and Weight management, Liver health (MASH) (Survodutide), respectively.
There's no universal "better" — it depends on your goal, and for most of these compounds robust head-to-head human evidence doesn't exist. The right choice is one made with a licensed professional. Selpho does not rank or prescribe; it offers educational information and a research-backed advisor.
They're in the same category, and combining research compounds is something to approach only with a licensed professional, since interactions and individual context matter. Selpho provides no dosing or protocols.
Retatrutide: Phase III clinical trials — investigational, not yet approved. Survodutide: Clinical trials — investigational.
