Selank
Similar to Semax. Purportedly, Semax is better for cognitive decline, and Selank is better for anxiety and/or depression.
Increases GABA release in the brain. Selank has a very short half-life (~2–3 minutes in plasma), which is why multiple daily administrations are usually used in research.
Dosage: 100mcg – 500mcg per dose, one or two times per day.
10mg vial with 1cc BAC water = 5 units per 500 mcg.
Semax
For neurodegenerative issues (Dementia, Alzheimer’s, Parkinson’s). Has cognitive function and memory formation mechanisms. Also neuroprotection in stroke and injury models.
The FDA is meeting with the Pharmacy Compounding Advisory Committee (PCAC) on 7/24/26 to evaluate Semax forcerebral ischemia, migraine, and trigeminal neuralgia.
Dosage: 200–600 mcg/day, often cycled (10–14 days on, 2–3 off); effects build over 3–7 days
