Hexarelin vs NA-Selank Amidate
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Hexarelin
Hexarelin is a potent synthetic hexapeptide growth hormone secretagogue. It provides the strongest GH release among GHRPs but is associated with rapid desensitization of receptors.
Full details →NA-Selank Amidate
NA-Selank Amidate (N-Acetyl Selank Amidate) is an enhanced version of Selank with improved stability and blood-brain barrier penetration. The modifications increase bioavailability and duration of cognitive and anxiolytic effects.
Full details →Side-by-Side Comparison
| Aspect | Hexarelin | NA-Selank Amidate |
|---|---|---|
| Mechanism | Acts as a ghrelin mimetic with high potency at the GHS receptor. Provides powerful GH release but receptor desensitization occurs faster than with other GHRPs, requiring cycling. | Same core mechanism as Selank - modulates BDNF, serotonin, and norepinephrine systems. The N-acetyl group improves membrane permeability while the amidate modification increases enzymatic stability. |
| Typical Dosage | Typical dosing: 100-200mcg administered 2-3 times daily for 4-6 weeks, followed by an equal off period to allow receptor resensitization. | Intranasal: 100-400mcg 1-3 times daily. Lower doses needed compared to standard Selank due to enhanced bioavailability. |
| Administration | Subcutaneous injection. Cycling is essential to maintain effectiveness. Often used in short bursts rather than continuous protocols. | Primarily intranasal administration. Can be used sublingually. More stable in solution than standard Selank. |
| Side Effects | Water retention, cortisol and prolactin increase, hunger (moderate), tingling, and potential blood pressure effects. | Generally well-tolerated. Possible mild fatigue or nasal irritation. Less frequent dosing needed than standard Selank. |
