NA-Semax Amidate vs Sermorelin
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.
Full details →Sermorelin
Sermorelin is a synthetic analog of GHRH consisting of the first 29 amino acids of the natural hormone. It was previously FDA-approved for GH deficiency diagnosis and treatment in children.

| Aspect | NA-Semax Amidate | Sermorelin |
|---|---|---|
| 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. | Binds to GHRH receptors in the pituitary gland to stimulate natural GH production and release. Maintains the body's natural feedback mechanisms for GH regulation. |
| Typical Dosage | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. | Typical dosing: 200-500mcg administered once daily, usually before bed. Some protocols use twice daily dosing. |
| Administration | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. | Subcutaneous injection, preferably at bedtime to work with natural GH release patterns. Can be combined with GHRPs for synergistic effects. |
| Side Effects | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. | Generally well-tolerated. May cause injection site reactions, headache, flushing, or dizziness. Less side effects than direct GH administration. |
