What is the best Semax dosage for beginners?

Beginners should start with 200-400 mcg per day, administered intranasally in the morning. This allows you to assess tolerance and sensitivity before increasing. Most users notice effects within the first few days at this dose.

How do I take Semax - nasal spray or injection?

Both methods are effective. Intranasal spray is more convenient and provides faster onset (15-30 minutes). Subcutaneous injection offers consistent absorption but requires more preparation. Most users prefer nasal administration for its ease of use.

Can I take Semax every day?

Semax can be taken daily during a cycle, but cycling is recommended to maintain sensitivity. A typical protocol is 4-6 weeks on, followed by 2-3 weeks off. Some users follow a 5-days-on, 2-days-off pattern for ongoing use.

What time of day should I take Semax?

Morning or early afternoon is recommended. Semax has stimulating properties that may interfere with sleep if taken too late in the day. If using twice daily, take the second dose before 3 PM.

How long does Semax take to work?

With intranasal administration, effects are typically noticed within 15-30 minutes. Peak effects occur within 1-2 hours. BDNF-related benefits may accumulate over the first 1-2 weeks of consistent use.

What happens if I take too much Semax?

Semax has a wide safety margin. High doses may cause temporary headache, overstimulation, or difficulty sleeping. There are no documented cases of serious adverse effects from high doses. If uncomfortable effects occur, reduce your dose.
