PE-22-28 vs Semax
| Attribute | PE-22-28 Spadin analog | Semax ACTH(4-10) analog |
|---|---|---|
| Category | Brain & Cognitive Support | Brain & Cognitive Support |
| Best known for | TREK-1 potassium channel antidepressant research | Cognitive enhancement research |
| In plain English | It blocks a brain potassium channel involved in mood regulation, aiming for fast-acting antidepressant effects. | Semax is the focus peptide. Researchers study how it boosts BDNF and NGF — the brain's growth and repair factors. |
| How it works | Selectively inhibits the TREK-1 two-pore potassium channel, enhancing serotonergic transmission in mood-relevant circuits. | Upregulates BDNF and NGF expression, modulates dopamine and serotonin, and inhibits enkephalin breakdown. |
| Researchers study | Depression, anxiety, and stress-resilience models. | Cognitive function, ischemic stroke recovery, ADHD, and neuroprotection. |
| Internet discussion | Discussed in advanced nootropic and mood research circles. | Stacked with Selank as the canonical Russian nootropic combo. |
PE-22-28
TREK-1 potassium channel antidepressant research
It blocks a brain potassium channel involved in mood regulation, aiming for fast-acting antidepressant effects.
Selectively inhibits the TREK-1 two-pore potassium channel, enhancing serotonergic transmission in mood-relevant circuits.
Depression, anxiety, and stress-resilience models.
Discussed in advanced nootropic and mood research circles.
PE-22-28 is a spadin-derived TREK-1 blocker researched as a fast-acting antidepressant peptide.
Semax
Cognitive enhancement research
Semax is the focus peptide. Researchers study how it boosts BDNF and NGF — the brain's growth and repair factors.
Upregulates BDNF and NGF expression, modulates dopamine and serotonin, and inhibits enkephalin breakdown.
Cognitive function, ischemic stroke recovery, ADHD, and neuroprotection.
Stacked with Selank as the canonical Russian nootropic combo.
Semax is a nootropic peptide researched for BDNF/NGF upregulation and cognitive support.
