NA-Semax Amidate vs Sermorelin & GHRP-2 & GHRP-6

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.

Sermorelin & GHRP-2 & GHRP-6

A powerful tri-blend combining Sermorelin (a GHRH analog) with two growth hormone releasing peptides. This combination produces significantly greater GH release than any single peptide, with studies showing up to 54-fold increases in pulsatile GH secretion.

Side-by-Side Comparison

AspectNA-Semax AmidateSermorelin & GHRP-2 & GHRP-6
MechanismMaintains Semax's core actions on BDNF, NGF, and monoamine systems with improved pharmacokinetics. The modifications enhance CNS penetration and extend duration of action.Sermorelin stimulates the pituitary via GHRH receptors, while GHRP-2 and GHRP-6 act as ghrelin mimetics on different receptor subtypes. The combination creates synergistic GH release through multiple complementary pathways. GHRP-6 also strongly stimulates appetite.
Typical DosageIntranasal: 100-600mcg 1-2 times daily. Start with lower doses as it's more potent than standard Semax.Typical protocols: Sermorelin 100-300mcg, GHRP-2 100-300mcg, GHRP-6 100-300mcg. Often administered 2-3 times daily, 30 minutes before meals or at bedtime.
AdministrationIntranasal spray is most common. Can be used sublingually. More stable than standard Semax in solution.Subcutaneous injection. Best administered fasted or before sleep to maximize natural GH cycle. The three peptides can be mixed together or administered separately.
Side EffectsMay cause irritability, hair shedding (rare), or overstimulation at high doses. Generally well-tolerated.Increased hunger (especially from GHRP-6), water retention, facial flushing, nausea, tingling, potential increases in cortisol and prolactin levels.
