GHRP-6 vs NA-Semax Amidate

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

GHRP-6

Growth Hormone Releasing Peptide 6 (GHRP-6) is one of the first synthetic growth hormone secretagogues discovered. It stimulates significant GH release but is known for causing intense hunger.

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.

Side-by-Side Comparison

AspectGHRP-6NA-Semax Amidate
MechanismActs as a ghrelin mimetic, binding to the GHS-R receptor in the pituitary and hypothalamus. Stimulates GH release and also significantly increases appetite by mimicking ghrelin's hunger-signaling effects.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 DosageTypical dosing: 100-300mcg administered 2-3 times daily. Often combined with GHRH peptides like CJC-1295 for synergistic effects.Intranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax.
AdministrationSubcutaneous injection. Best administered on an empty stomach. The strong hunger response can be beneficial for those trying to gain weight but challenging for cutting.Intranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution.
Side EffectsIntense hunger (most notable effect), water retention, increased cortisol and prolactin, tingling/numbness, and potential blood pressure changes.May cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated.
