N‑Acetyl Semax — enhanced nootropic peptide by Hilma Biocare
N‑Acetyl Semax is a synthetic analogue of the ACTH 4‑10 fragment, modified with an N‑acetyl group that markedly increases its half‑life and bio‑availability. The peptide is non‑hormonal but delivers potent nootropic, neuro‑protective, antioxidant and antihypoxic actions, helping both mental and physical performance.
Main properties
- Memory & learning boost: Improves concentration, recall and acquisition of new information.
- BDNF up‑regulation: Stimulates brain‑derived neurotrophic factor, supporting synaptic plasticity.
- Neuroprotection: Shields neurons from ischemic stress and hypoxia.
- Accelerated rehab: Speeds recovery after stroke or traumatic brain injury.
- Antioxidant & antihypoxic: Reduces oxidative damage and improves cellular oxygen utilization.
Indications (medical use)
- Ischemic stroke & transient ischemic attacks
- Memory and cognitive impairment
- Gastric ulcer support
- Optic‑nerve disorders (e.g., optic atrophy)
- Immune‑system strengthening
- General mental‑fatigue and nervous exhaustion prophylaxis
Administration routes
- Intranasal (nasal drops): Rapid BBB penetration (~4 min).
- Sub‑cutaneous (abdominal fatty tissue) for slower, sustained release.
Dosage & protocol (research/clinical regimens)
- Mental fatigue: 0.1–0.3 mg 1–3 × daily for 3–7 days.
- Optic‑nerve atrophy: 0.3 mg 1–3 × daily for 7–10 days (extend ≤30 days if needed).
- Cognitive impairment post‑stroke/encephalopathy: up to 2 mg 2–4 × daily for 10–14 days; repeatable.
- Traumatic brain injury: 1–3.5 mg 3 × daily for 3–5 days (extend ≤14 days).
- Moderate stroke: 2–3 mg 3–4 × daily (3–4 h intervals) for 10 days; repeat after 20‑day break.
- Severe stroke: 3–4 mg 4–6 × daily (2.5–3 h intervals) for 10 days.
- Prophylactic for nervous exhaustion: 0.2–0.5 mg 1–2 × daily for up to 30 days.
Contra‑indications
- Hypersensitivity to any component.
- Pregnancy or lactation.
- Acute psychosis, anxiety disorders.
- History of seizures.
- Children under 5 years of age.
Drug interactions
- Do not combine with other stimulants or nootropic agents without medical guidance.
Side effects
- Mild nasopharyngeal discomfort (intranasal) or slight injection‑site swelling (sub‑cut.) – usually due to technique, not the peptide.
- Adverse events are rare when administered correctly.
Compatibility with other products
N‑Acetyl Semax can be stacked with performance‑enhancing compounds (peptides, adaptogens, certain vitamins) when overseen by a physician, allowing synergistic cognitive‑recovery protocols.
Conclusion
N‑Acetyl Semax by Hilma Biocare provides a stable, bio‑available nootropic that supports memory, neuro‑protection and post‑stroke rehabilitation. Individualized dosing, professional monitoring and proper administration routes are essential for optimal results.
