NA-Semax Amidate vs Cagrilintide

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

NA-Semax Amidate

NA-Semax Amidate (N-Acetyl Semax Amidate) is a modified version of Semax with enhanced stability and potency. Also known as NASA, it provides stronger and longer-lasting nootropic effects than standard Semax.

Cagrilintide

Cagrilintide is a long-acting amylin analog in development, showing promising results when combined with semaglutide (CagriSema). Amylin is a hormone co-secreted with insulin that promotes satiety.

Side-by-Side Comparison

AspectNA-Semax AmidateCagrilintide
MechanismMaintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action.Activates amylin receptors (calcitonin receptor with RAMP proteins) to slow gastric emptying, suppress glucagon secretion, and reduce food intake through central satiety mechanisms distinct from GLP-1.
Typical DosageIntranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax.Clinical trials: 2.4mg weekly as monotherapy or in combination with semaglutide 2.4mg (CagriSema). Optimal dosing still being determined.
AdministrationIntranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution.Subcutaneous injection once weekly. Currently only available in clinical trials - not yet FDA approved.
Side EffectsMay cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated.Nausea, vomiting, diarrhea, constipation similar to other incretin-based therapies. Combination with semaglutide may increase GI effects initially.
