HGH Fragment 176-191 vs NA-Semax Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
HGH Fragment 176-191
HGH Fragment 176-191 is the fat-reducing portion of the growth hormone molecule. Unlike AOD-9604 (which has an additional tyrosine), this is the exact fragment of HGH responsible for lipolytic effects.
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.

| Aspect | HGH Fragment 176-191 | NA-Semax Amidate |
|---|---|---|
| Mechanism | Mimics the lipolytic region of growth hormone, stimulating fat breakdown and inhibiting lipogenesis without affecting blood sugar or promoting growth. Works independently of GH receptors. | 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 | Typical dosing: 250-500mcg daily, often split into 2-3 doses. Usually administered on empty stomach, often with fasted cardio. | Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax. |
| Administration | Subcutaneous injection. Best results when used fasted and combined with exercise. Avoid eating for 30 minutes post-injection. | Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution. |
| Side Effects | Generally well-tolerated. May cause injection site irritation, temporary lethargy, or headache. Does not affect blood glucose significantly. | May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated. |
