Retatrutide vs Tirzepatide

Tirzepatide is the current standard dual-agonist (GLP-1 + GIP). Retatrutide adds a third receptor — glucagon — for more aggressive metabolic effect in research.

Retatrutide
Tirzepatide
Tagline
Triple agonist (GLP-1 + GIP + glucagon)
Dual agonist (GLP-1 + GIP)
Mechanism
Activates GLP-1, GIP, and glucagon receptors — adds energy expenditure on top of appetite suppression.
Activates GLP-1 and GIP receptors — appetite suppression plus insulin sensitization.
Half-life
~6 days (once-weekly dosing)
~5 days (once-weekly dosing)
Typical dose
Titrated 0.5 mg → 8 mg weekly over 8+ weeks
Titrated 2.5 mg → 15 mg weekly
Primary use
Aggressive metabolic recomposition research
Established metabolic research, well-documented profile
Stack fit
Standalone. Some research pairs with MOTS-c for mitochondrial support.
Standalone. Compatible with NAD+ and MOTS-c.
Side-effect profile
GI effects scale with dose. Slow titration is standard.
GI effects during titration; well-characterized in literature.
Best for
Research targeting larger metabolic shifts than Tirzepatide produces.
Researchers preferring a more documented profile.

When To Pick Which

◆ Pick Retatrutide when

More aggressive research targets or plateau on dual-agonist protocols.

◆ Pick Tirzepatide when

Larger research base, well-characterized titration schedule.

◆ Run them together when

Not stacked — both occupy the same receptor space. Choose one.

FAQ

Is Retatrutide stronger than Tirzepatide?

Research suggests larger metabolic effect per dose due to the added glucagon agonism, but side-effect profile scales accordingly.

Can you switch between them?

Researchers typically wash out one before titrating into the other; combining is not standard.
