Adamax vs Noopept
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Adamax
Adamax is a modified version of Semax with an adamantane group attached, designed to enhance its nootropic effects and extend duration of action compared to standard Semax.
Full details →Noopept
Noopept (N-phenylacetyl-L-prolylglycine ethyl ester) is a peptide-derived nootropic developed in Russia. While technically a dipeptide prodrug rather than a true peptide, it's often discussed alongside peptide nootropics.
Full details →Side-by-Side Comparison
| Aspect | Adamax | Noopept |
|---|---|---|
| Dose Range | 200 mcg–750 mcg | 10 mg–30 mg |
| Frequency | 1x daily | 2x daily |
| Cycle Length | 2–4 weeks | 4–6 weeks |
| Route | intranasal | oral |
| Mechanism | Similar to Semax - enhances BDNF expression and modulates dopamine/serotonin systems. The adamantane modification may increase lipophilicity and CNS penetration. | Metabolized to cycloprolylglycine which modulates AMPA and NMDA receptors, increases NGF and BDNF expression, and provides neuroprotective effects through antioxidant mechanisms. |
| Typical Dosage | Intranasal: 100-500mcg 1-2 times daily. Lower doses than standard Semax may be effective due to enhanced potency. | Oral: 10-30mg daily, typically divided into 2-3 doses. Sublingual use may enhance absorption. Some users go higher but effects may plateau. |
| Administration | Intranasal spray is most common route. More stable than standard Semax. Often used for acute cognitive enhancement. | Oral or sublingual administration. Unlike most peptides, it's orally bioavailable. Can be taken with or without food. |
| Side Effects | Similar to Semax - possible irritability, hair shedding, or overstimulation. May have stronger effects than standard Semax. | Headache (often from choline depletion), irritability, insomnia if taken late, and occasional brain fog during initial use. |
