NA-Semax Amidate vs Pramlintide
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.

Pramlintide (Symlin) is a synthetic analog of amylin, FDA-approved as an adjunct to insulin therapy in type 1 and type 2 diabetes. It helps control post-meal blood sugar spikes and promotes modest weight loss.

| Aspect | NA-Semax Amidate | Pramlintide |
|---|---|---|
| Mechanism | Maintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action. | Mimics amylin's effects: slows gastric emptying, suppresses glucagon secretion after meals, and promotes satiety through central mechanisms. Complements insulin therapy. |
| Typical Dosage | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. | Type 1: Start 15mcg before meals, titrate to 30-60mcg. Type 2: Start 60mcg, may increase to 120mcg. Always with meal containing 30+ grams carbs or 250+ calories. |
| Administration | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. | Subcutaneous injection immediately before major meals. Must reduce mealtime insulin by 50% when starting to prevent hypoglycemia. Never mix with insulin. |
| Side Effects | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. | Nausea (very common initially), headache, anorexia, vomiting, and abdominal pain. GI effects typically improve over time. |
