Retatrutide 20mg
₡ 61,346
Retatrutide 20mg is an advanced research peptide associated with metabolic wellness, appetite regulation, body composition support, and weight-management research. Known for its multi-receptor activity, Retatrutide has gained attention for its relationship with GLP-1, GIP, and glucagon pathways, making it one of the most discussed peptides in modern metabolic optimization.
Unlike traditional single-pathway treatments, Retatrutide activates GLP-1, GIP, and glucagon receptors simultaneously, which may result in significantly enhanced outcomes in weight reduction and metabolic improvement. It is widely researched for its potential to support individuals dealing with obesity, insulin resistance, and overall metabolic dysfunction.

Product Information
Retatrutide is a multi-agonist peptide studied for its activity across three important metabolic receptor systems: GLP-1, GIP, and glucagon receptors. These pathways are involved in appetite signaling, energy balance, glucose metabolism, insulin response, and how the body manages fuel.
Its triple-receptor profile is what makes Retatrutide different from many metabolic peptides that focus primarily on GLP-1 activity. By engaging multiple pathways, Retatrutide has become a major focus in research related to body weight regulation, metabolic function, and obesity science.
In clinical research settings, Retatrutide has been investigated for significant weight-management outcomes and metabolic improvements. However, it remains a developing compound and should not be presented as a guaranteed result or substitute for medical treatment.
For buyers, Retatrutide 20mg offers a premium, research-driven peptide option for those interested in modern metabolic science, appetite control, and advanced body composition support.

Common Questions
Frequently Asked Questions
Is the 20mg Retatrutide vial well suited for a full research cycle? +
Yes. The 20mg vial provides approximately 10 doses at 2 mg per dose — sufficient for a standard research cycle. It balances cost-per-dose efficiency with manageable vial size, making it one of the most practical options for sustained Retatrutide research.
How much BAC water should I add to a 20mg Retatrutide vial? +
Add 2 mL of bacteriostatic water for 10 mg/mL concentration. Use the reconstitution calculator with 20mg as the vial amount for precise syringe units based on your dose.
How many doses does a 20mg Retatrutide vial provide? +
With 2 mL BAC water (10 mg/mL), the vial provides approximately 10 doses at 2 mg, or 6–7 doses at 3 mg per dose.
How does Retatrutide compare to Semaglutide in research? +
Retatrutide is a triple agonist (GLP-1R + GIPR + GCGR) versus Semaglutide, which is a single GLP-1 receptor agonist. In Phase 2 clinical trials, Retatrutide demonstrated greater average weight reduction than Semaglutide. The additional GIPR and GCGR activity increases energy expenditure and fat oxidation beyond GLP-1-only mechanisms.
How should the 20mg Retatrutide vial be stored? +
Store sealed at ≤ −20 °C before reconstitution. After reconstitution, refrigerate at 2–8 °C and use within 28–30 days. Avoid freeze-thaw cycles and agitation. Slight turbidity is normal for lipid-conjugated peptides.
