Pinealon vs Semax
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Pinealon
Pinealon is a short synthetic peptide developed from research on the pineal gland. It has shown neuroprotective and cognitive-enhancing properties in animal studies.
Full details →Semax
Semax is a synthetic peptide derived from ACTH (adrenocorticotropic hormone). Developed in Russia as a nootropic and neuroprotective agent.
Full details →Side-by-Side Comparison
| Aspect | Pinealon | Semax |
|---|---|---|
| Dose Range | 5 mg–10 mg | 300 mcg–600 mcg |
| Frequency | 1x daily | 2x daily |
| Cycle Length | 1–2 weeks | 2–4 weeks |
| Route | subcutaneous | intranasal |
| Mechanism | Penetrates cell membranes and interacts with DNA to regulate gene expression related to neuronal survival and function. May support pineal gland function and melatonin production. | Enhances BDNF expression, modulates dopamine and serotonin systems, and provides neuroprotective effects. Increases attention, memory formation, and learning. |
| Typical Dosage | Typical dosing: 10-20mg daily, taken in divided doses. Often used in cycles of 10-20 days. | Intranasal: 200-600mcg 2-3 times daily. Higher doses (up to 1mg) used in clinical settings for stroke recovery. |
| Administration | Can be taken orally (capsules) or sublingually. Best absorbed on an empty stomach. Often combined with other neuroprotective peptides. | Primarily administered intranasally. N-Acetyl Semax Amidate (NASA) is a modified version with enhanced stability and potency. |
| Side Effects | Generally well-tolerated. Limited reported side effects. May affect sleep patterns initially. | Generally well-tolerated. May cause mild irritability or hair shedding in some users. |
