NA-Selank Amidate vs Retatrutide

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

NA-Selank Amidate

NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects.

Retatrutide

Retatrutide is an investigational triple agonist targeting GIP, GLP-1, and glucagon receptors. Phase 2 trials showed unprecedented weight loss of up to 24% at 48 weeks, making it potentially the most effective obesity treatment studied.

Side-by-Side Comparison

AspectNA-Selank AmidateRetatrutide
MechanismSame core mechanism as Selank - modulates BDNF, serotonin, and norepinephrine systems. The N-acetyl group improves membrane permeability while the amidate modification increases enzymatic stability.Triple receptor activation provides complementary metabolic effects: GLP-1 and GIP reduce appetite and improve insulin sensitivity, while glucagon receptor activation increases energy expenditure and promotes hepatic fat oxidation.
Typical DosageIntranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability.Clinical trials used doses from 1mg to 12mg weekly. Optimal dosing still being determined in ongoing Phase 3 trials.
AdministrationPrimarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank.Subcutaneous injection once weekly. Currently only available through clinical trials - not yet FDA approved.
Side EffectsGenerally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank.Similar GI effects to other incretin-based therapies: nausea, diarrhea, vomiting, constipation. Dose-dependent severity.
