NA-Semax Amidate vs MGF (Mechano Growth Factor)
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 →MGF (Mechano Growth Factor)
MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is produced locally in muscle tissue in response to mechanical stress. The non-PEGylated form has a very short half-life.

| Aspect | NA-Semax Amidate | MGF (Mechano Growth Factor) |
|---|---|---|
| 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. | Activates muscle satellite cells (stem cells) and promotes their proliferation without differentiation, priming them for fusion with existing muscle fibers during repair and growth. |
| Typical Dosage | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. | Due to extremely short half-life (minutes), typical protocols use 100-200mcg injected directly into target muscles immediately post-workout. |
| Administration | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. | Intramuscular injection into trained muscles within minutes of workout completion. Must be used immediately after reconstitution due to instability. |
| Side Effects | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. | Injection site soreness, potential hypoglycemia, localized swelling. Short half-life limits systemic effects. |
