Human Growth Hormone (HGH) vs NA-Semax Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Human Growth Hormone (HGH)
Human Growth Hormone (somatropin) is a 191-amino acid protein identical to naturally produced GH. FDA-approved for growth hormone deficiency, Turner syndrome, and other conditions. Widely used off-label for anti-aging and performance.
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 | Human Growth Hormone (HGH) | NA-Semax Amidate |
|---|---|---|
| Mechanism | Binds to GH receptors throughout the body, stimulating IGF-1 production in the liver. Promotes protein synthesis, fat metabolism, and cellular regeneration across multiple tissues. | 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 | Medical: 0.1-0.3mg/kg/week divided into daily doses. Anti-aging: 1-2 IU daily. Performance: 2-6 IU daily, sometimes higher. | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. |
| Administration | Subcutaneous injection, preferably at night to mimic natural pulsatile release. Rotate injection sites. Store refrigerated. | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. |
| Side Effects | Joint pain, water retention, carpal tunnel syndrome, potential insulin resistance, and acromegaly features with long-term high doses. | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. |
