Semaglutide vs NA-Semax Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Semaglutide
Semaglutide is a GLP-1 receptor agonist that has revolutionized weight management and diabetes treatment. FDA-approved as Ozempic (diabetes), Wegovy (weight loss), and Rybelsus (oral form), it has become one of the most prescribed peptides worldwide.
Full details →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.
Full details →Side-by-Side Comparison
| Aspect | Semaglutide | NA-Semax Amidate |
|---|---|---|
| Mechanism | Mimics glucagon-like peptide-1 (GLP-1) to stimulate insulin secretion, suppress glucagon release, slow gastric emptying, and reduce appetite through hypothalamic signaling. The result is significant reduction in food intake and improved glycemic control. | Maintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action. |
| Typical Dosage | Wegovy (weight loss): Start at 0.25mg weekly, titrate up to 2.4mg weekly over 16-20 weeks. Ozempic (diabetes): 0.25mg to 1mg weekly. Research protocols vary. | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. |
| Administration | Subcutaneous injection once weekly, typically in abdomen, thigh, or upper arm. Rybelsus is taken orally on empty stomach. Dose titration is essential to minimize GI side effects. | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. |
| Side Effects | Common: nausea, vomiting, diarrhea, constipation, abdominal pain. These typically decrease over time. May cause injection site reactions. | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. |
