DOSING GUIDE

Retatrutide 15mg

Retatrutide is a triple agonist targeting GLP-1, GIP, and glucagon receptors simultaneously, making it the most aggressive weight loss peptide in late-stage clinical development. It outperforms semaglutide and tirzepatide in trial data, with Phase 3 showing up to 24% body weight reduction — the highest of any injectable peptide to date.

Tips & Notes

Timing

Once weekly subcutaneous injection, same day each week — consistency matters more than time of day. Dosing in the evening can help sleep through the worst of early nausea.

Cycling

No defined cycle length — designed as a long-term chronic therapy like semaglutide. Discontinuation typically results in weight regain, so stopping should be intentional and paired with a maintenance strategy.

Stacking

Avoid stacking with other GLP-1 agonists — redundant and compounds GI side effects badly. Pairs well with HHB for micronutrient support since appetite suppression at this level can create deficiencies.

Storage

Lyophilized: fridge for regular use, freezer for long-term. Reconstituted: fridge only, use within 4 weeks, never freeze reconstituted vials, protect from light.
