01 / SIGNAL
Suppress appetite
GLP-1 activation slows gastric emptying and signals satiety in the brain — you eat less without fighting hunger.
Signature Line · Triple Agonist
Reta
Retatrutide.
The next generation of metabolic optimization. Retatrutide acts on three receptors at once — GLP-1, GIP, and glucagon — driving stronger fat loss and metabolic control than single-pathway peptides.

// 01What it is
Retatrutide is a third-generation incretin peptide developed for advanced metabolic and weight-management research. Where Semaglutide hits one receptor and Tirzepatide hits two, Reta hits three.
By co-activating GLP-1, GIP, and glucagon receptors, Reta works on appetite, insulin sensitivity, and energy expenditure simultaneously — the reason recent trial data has shown it producing the strongest fat-loss numbers in its class.
It's the flagship of the Max Nutrition USA collection because it consistently outperforms single- and dual-agonist peptides for users running an aggressive fat-loss or recomposition protocol.
// 02How it works
Four mechanisms working in parallel — that's why a triple agonist outperforms single-pathway peptides for body-composition outcomes.
02 / STABILIZE
Control glucose
GIP and GLP-1 together improve insulin sensitivity and blunt post-meal blood-sugar spikes.
03 / BURN
Mobilize fat
Glucagon activation raises resting energy expenditure and pushes the body to use stored fat for fuel.
04 / RESULTS
Recompose
Net effect: reduced cravings, lower body fat, tighter physique — without the muscle loss seen on aggressive cuts.
// 03Key benefits
Strongest fat-loss class
Triple-receptor activation drives outcomes single- and dual-agonists can't match.
Reduced cravings
Cleaner appetite control — fewer "snack attacks" and better adherence to your nutrition plan.
Better glucose control
Smoother blood sugar curves, less crash, more consistent energy through the day.
Higher energy expenditure
Glucagon activity raises baseline metabolic rate — you burn more sitting still.
Once-weekly dosing
Long half-life means one injection per week. Simple, sustainable, easy to comply with.
Stacks cleanly
Pairs well with BPC+TB for joint support during fat loss, or CJC+Ipa for lean-mass preservation.
