Typical routine is 1–2 drops per nostril, 2× each day, lasting 10–14 days
→ Prevention of cognitive fatigue (college students, excessive workload):
Protocols suggest 2 drops per nostril, a few times each day in periods of psychological stress, for as much as 2 weeks.
1% Semax Answer (Medical/Neurological Use)
→ Stroke and ischemic damage:
Utilized in extra severe neurological circumstances, with dosing of two–3 drops per nostril, 3–4× each day, for five–10 days
→ Optic nerve illness:
Protocols mirror the stroke dosing, with therapy durations extending as much as 10 days, typically repeated after a break.
Basic Tips
→ Drops ought to be administered immediately onto the nasal mucosa, with the pinnacle tilted barely again to keep away from drainage into the throat.
→ Typical course lengths are short-term (5–16 days) somewhat than steady long-term dosing.
→ Repeat cycles are potential after a 1–3 month interval relying on indication.

Nootropic and Experimental Dosing
Exterior of Russia’s medical settings, Semax has gained reputation within the nootropic neighborhood for its focus, reminiscence, and mood-enhancing results. Since it’s not FDA-approved, dosing is commonly tailored from Russian prescribing practices and anecdotal person stories.
Widespread Nootropic Protocols
→ Microdosing for focus:
0.1% resolution at 1–2 drops per nostril, 1–2× each day, used for five–10 days in periods of excessive cognitive demand
→ Productiveness / studying cycles:
Quick-term programs of 10–14 days, then discontinued. Some customers repeat cycles each 1–3 months to keep away from tolerance.
Variations from Medical Apply
→ Delicate neuroprotection: Larger-frequency dosing (as much as 2–3× each day) is typically utilized by biohackers, although most keep inside medical 0.1% tips.
→ Mixture with different nootropics: Anecdotally, Semax is paired with Selank for stress/focus stability, or stimulants like caffeine to reinforce consideration.
Sensible Use Concerns
→ Semax is often taken intranasally solely — oral or sublingual routes have very poor bioavailability.
→ Most customers favor morning and early afternoon dosing to align with pure cognitive rhythms and keep away from potential overstimulation within the night.
