Retatrutide

Triple-Action Protocol

5mg × 10 vialsWeight Loss

10 vials — 12 months supply

The most anticipated next-generation weight loss compound. Phase 3 results generated massive excitement. The "24% weight loss" headline circulates widely.

What it does

Retatrutide is a triple agonist targeting GLP-1, GIP, and glucagon receptors simultaneously. The addition of glucagon receptor activation increases energy expenditure and hepatic fat oxidation — mechanisms absent from dual and single agonists.

This three-pathway approach represents the cutting edge of incretin-based research. Glucagon's role in increasing basal metabolic rate adds an energy expenditure component that pure appetite suppression compounds lack.

Dosage & Protocol

Subcutaneous injection, once weekly. Titration: 1mg (month 1), 2mg (month 2), 4mg (month 3), 8-12mg (month 4+). 10 vials provides approximately 12 months. Still in Phase 3 — no established clinical protocol yet.

What to expect

1
Week 1-4: Initial appetite suppression, mild nausea during titration. Minimal scale change.
2
Week 4-12: Appetite drops significantly. Weight loss accelerates. Glucagon component may increase energy/metabolic rate.
3
Week 12-24: Aggressive weight loss — clinical data shows ~17% body weight loss by 24 weeks at 12mg dose.
4
Week 24-48: Continued loss approaching 24% of body weight. Phase 3 average was 71.2 lbs lost. Weight loss still continuing at study end.

Who it's for

Researchers studying the next generation of incretin-based compounds
Those looking for the most advanced multi-pathway metabolic compound available
Researchers focused on hepatic fat reduction and energy expenditure
Anyone following the latest developments in GLP-1 research

The research

📄
Phase 2 Trial (NEJM): 24.2% weight loss at 48 weeks — highest ever recorded in clinical trial(10.1056/NEJMoa2301972)
📄
Systematic review: Efficacy and safety of retatrutide for obesity treatment(PMC12026077)

Safety notes

⚠️Common side effects: GI events (nausea, diarrhea, vomiting) — dose-dependent, manageable with slow escalation.
⚠️Glucagon-specific: May increase heart rate. Blood sugar monitoring recommended.
⚠️Regulatory status: Phase 3 trials ongoing (Eli Lilly). NOT FDA-approved. Research/gray market only.
⚠️Muscle preservation even more critical given extreme weight loss rates.
