Adamax vs PE-22-28
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 →PE-22-28
PE-22-28 is a synthetic peptide fragment derived from research on the SAMP8 mouse model of accelerated aging. It has shown potential for enhancing memory and reducing cognitive decline.
Full details →Side-by-Side Comparison
| Aspect | Adamax | PE-22-28 |
|---|---|---|
| Mechanism | Similar to Semax - enhances BDNF expression and modulates dopamine/serotonin systems. The adamantane modification may increase lipophilicity and CNS penetration. | Derived from the protein that is deficient in SAMP8 mice. May work by inhibiting protein phosphatase 2A methylesterase, thereby affecting memory-related signaling pathways. |
| Typical Dosage | Intranasal: 100-500mcg 1-2 times daily. Lower doses than standard Semax may be effective due to enhanced potency. | Research protocols vary. Intranasal dosing has been studied at various concentrations. Optimal human dosing not established. |
| Administration | Intranasal spray is most common route. More stable than standard Semax. Often used for acute cognitive enhancement. | Intranasal administration preferred for CNS delivery. Research compound with limited human use data. |
| Side Effects | Similar to Semax - possible irritability, hair shedding, or overstimulation. May have stronger effects than standard Semax. | Very limited human data. Primarily studied in animal models for safety and efficacy. |
