Retatrutide 20 by Zyvex Pharmaceuticals
What Is Retatrutide 20?
Retatrutide is a triple-agonist research peptide that targets the GLP-1, GIP and glucagon receptors, and it has become one of the most discussed compounds in metabolic research. Zyvex Pharmaceuticals supplies it as a 20 mg lyophilized vial for reconstitution.
The triple mechanism separates retatrutide from single-pathway GLP-1 compounds: glucagon agonism adds an energy-expenditure component on top of the appetite effect. Research interest centers on body weight and metabolic markers, with dosing built around slow weekly titration rather than fixed daily amounts.
Retatrutide Research Use
Retatrutide is dosed subcutaneously once weekly, starting low and titrating up over weeks.
| Phase | Weekly Dose | Notes |
|---|---|---|
| Start | 1-2 mg | First 2-4 weeks |
| Mid titration | 4-8 mg | By tolerance Common |
| Higher research range | 8-12 mg | Experienced protocols |
Reconstitute with bacteriostatic water per the research protocol and refrigerate. The 20 mg vial covers 2-10 weeks depending on the titration stage.
Retatrutide Stacks
Retatrutide is a triple-agonist GLP research peptide for metabolic studies. The stacks below pair it with Zyvex Pharmaceuticals research products.
| Stack | Goal |
|---|---|

| Retatrutide 20 + Semaglutide 10 | GLP research comparison protocols |
Retatrutide Side Effects
The side profile follows the GLP-1 family: gastrointestinal effects dominate, especially while titrating.
- Heart rate - mild resting heart rate increase has been reported in research.
- Energy - calorie intake drops fast; plan nutrition intentionally.
- Research status - experimental compound for laboratory use only.

What is Retatrutide?
Retatrutide is a triple-agonist research peptide targeting the GLP-1, GIP and glucagon receptors. Zyvex Pharmaceuticals supplies it as a 20 mg lyophilized vial.
How does Retatrutide differ from Semaglutide?
Semaglutide targets only GLP-1, while Retatrutide adds GIP and glucagon agonism, which adds an energy-expenditure component to the appetite effect.
What is the right Retatrutide dose and titration?
Retatrutide is dosed subcutaneously once weekly, starting at 1-2 mg and titrating up over weeks by tolerance, up to the 8-12 mg research range.
How long does Retatrutide take to work?
Appetite effects begin in the first weeks; metabolic and weight effects build over the full titration window of 8-16 weeks.
What are the Retatrutide side effects?
Gastrointestinal effects dominate, as with GLP-1 compounds: nausea, appetite loss and digestive slowing. A mild heart-rate increase has been reported in research.
How long does Retatrutide stay in your system?
Retatrutide has a long half-life that supports once-weekly dosing.
How do you reconstitute Retatrutide?
Reconstitute the 20 mg vial with bacteriostatic water per the research protocol and refrigerate between doses.
Why is Retatrutide called a triple agonist?
It activates GLP-1, GIP and glucagon receptors at once, which is the mechanism behind its metabolic research interest.
Is Retatrutide for weight loss research?
Yes, metabolic and body-composition research is the main interest in Retatrutide, driven by the appetite and energy-expenditure effects.
