Semax vs KPV
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Semax
Semax is a synthetic peptide derived from ACTH (adrenocorticotropic hormone). Developed in Russia as a nootropic and neuroprotective agent.
Full details →KPV
KPV is a tripeptide (Lys-Pro-Val) derived from alpha-melanocyte-stimulating hormone (α-MSH). It retains the potent anti-inflammatory properties of the parent hormone without the tanning or other melanocortin effects.

| Aspect | Semax | KPV |
|---|---|---|
| Mechanism | Enhances BDNF expression, modulates dopamine and serotonin systems, and provides neuroprotective effects. Increases attention, memory formation, and learning. | Inhibits NF-κB activation and reduces inflammatory cytokine production. Enters cells and directly modulates inflammatory signaling without requiring melanocortin receptors. |
| Typical Dosage | Intranasal: 200-600mcg 2-3 times daily. Higher doses (up to 1mg) used in clinical settings for stroke recovery. | Oral/sublingual: 200-500mcg 1-3 times daily. Topical formulations for localized inflammation. Also used in enemas for gut inflammation. |
| Administration | Primarily administered intranasally. N-Acetyl Semax Amidate (NASA) is a modified version with enhanced stability and potency. | Can be taken orally, sublingually, or as suppositories/enemas for gut inflammation. Topical use for skin conditions. Stable orally unlike most peptides. |
| Side Effects | Generally well-tolerated. May cause mild irritability or hair shedding in some users. | Generally very well-tolerated. Minimal systemic effects due to targeted anti-inflammatory action. |
