GLP-1s
Semaglutide, tirzepatide, and retatrutide are three different receptor strategies — not three doses of the same drug. Each one answers the same question about hunger, fat, and lean mass in a different way.
Three compounds, three receptor strategies. Semaglutide activates GLP-1 alone — SELECT showed a 20% cardiovascular event reduction in obesity with established heart disease. Tirzepatide adds GIP and delivered 47% more weight loss than semaglutide in the head-to-head SURMOUNT-5 trial. Retatrutide adds glucagon on top, pushing the weight-loss ceiling higher and mobilizing liver fat directly, though it remains investigational. Pick by the outcome you need, not the headline number.

Retatrutide is an investigational triple agonist. What the trial data show for weight loss and liver fat, where microdose logic is supported, and where the evidence still needs caution.

Retatrutide vs TirzepatideSame Receptors, Different Drug
Retatrutide and tirzepatide are not stronger/weaker versions of the same drug. Tirz is the steadier default; reta adds glucagon, liver-fat leverage, and much higher titration risk.
GLP-1 FatigueWhy It Happens and What Helps
GLP-1 fatigue explained: why semaglutide, tirzepatide, and retatrutide cause tiredness, which compound causes more, and evidence-based fixes from protein to mitochondrial support.
