Semaglutide vs Retatrutide

Semaglutide is the single-agonist (GLP-1 only) benchmark. Retatrutide is the newer triple agonist (GLP-1 + GIP + glucagon) for more aggressive research targets.

Semaglutide
Retatrutide
Tagline
Single agonist (GLP-1)
Triple agonist (GLP-1 + GIP + glucagon)
Mechanism
Pure GLP-1 receptor agonist. Appetite suppression and gastric emptying delay.
Adds GIP (insulin sensitivity) and glucagon (energy expenditure) on top of GLP-1.
Half-life
~7 days
~6 days
Typical dose
Titrated 0.25 mg → 2.4 mg weekly
Titrated 0.5 mg → 8 mg weekly
Primary use
Established appetite/glucose research
Aggressive metabolic research
Stack fit
Standalone. Pairs with NAD+ for energy research.
Standalone. Pairs with MOTS-c.
Side-effect profile
Well-characterized GI profile during titration.
GI effects scale with dose; slow titration is standard.
Best for
Researchers preferring the most-documented profile.
Research targeting larger metabolic shifts.

When To Pick Which

◆ Pick Semaglutide when

Conservative, well-documented protocol with broad research base.

◆ Pick Retatrutide when

More aggressive research targets, multi-pathway interest.

◆ Run them together when

Not stacked — same receptor family. Choose one.

FAQ

Which is newer?

Retatrutide. Semaglutide has years of additional research backing it.

Is the dosing equivalent?

No — they titrate on different scales. Always follow the per-compound titration schedule.
