Epithalamin vs NA-Semax Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Epithalamin
Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.
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 | Epithalamin | NA-Semax Amidate |
|---|---|---|
| Mechanism | Similar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms. | 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 | Research dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols. | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. |
| Administration | Intramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon. | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. |
| Side Effects | Generally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon. | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. |
