CORTEXIN

RECONSTITUTION & PROTOCOL

📖 OVERVIEW

Cortexin is a polypeptide complex extracted from bovine brain cortex, containing low-molecular-weight neuropeptides that cross the blood-brain barrier. It has neuroprotective and nootropic effects, enhancing neuronal metabolism and repair. Improves cognitive function, memory, focus, and mental clarity. Reduces brain fog and supports recovery from stroke, TBI, or neurodegenerative conditions.

Russian clinical data and animal studies demonstrate Cortexin accelerates brain recovery after ischemic stroke, improves EEG patterns, and enhances cognitive performance in aging models. Cerebrolysin for comprehensive neuropeptide support; Semax for amplified cognitive enhancement.

⚠️ Note: Cycles recommended (not continuous use). Potential allergic reaction to bovine proteins. Not for individuals with prion disease risk.

💧 RECONSTITUTION & ROUTE

Reconstitute 10 mg vial with 2 mL bacteriostatic water (or sterile saline)
Route: Intramuscular (IM) injection only: gluteal (upper outer buttock) or deltoid (upper arm), 27–30 gauge needle. Community/Wikipedia clinical convention: 10 mg IM daily.

FINAL CONCENTRATION:

5 mg/mL (10 mg ÷ 2 mL)
1 unit on a U-100 insulin syringe = ~0.05 mg (50 mcg) CORTEXIN

📊 DOSE CONVERSION

DOSE (CORTEXIN) U-100 SYRINGE
5 mg 100 units (1 mL)
10 mg 200 units (2 mL)

📅 GENERAL TITRATION PROTOCOL

COURSE

10 mg/day IM (200 units) • daily for a 10-day course; standard adult neuroprotective convention

COURSE+

Repeat 1–2× per year, or every 3–6 months • off-period between courses

♻️ CYCLING INFORMATION

Standard Protocol

Course length: 10 consecutive days of daily 10 mg IM injection.
Off-period: Repeat 1–2× per year, or every 3–6 months depending on goal.

⚡ SYNERGY & CAUTION

✅ SYNERGISTIC

  • Cerebrolysin
    Both are neuropeptide complexes historically combined in Eastern European neurology protocols to support neurotrophic signaling from complementary angles.
  • Citicoline (CDP-choline)
    Supports phospholipid membrane repair and acetylcholine synthesis, complementing neuropeptide-driven neurotrophic support.
  • Omega-3 (DHA-rich)
    DHA is a structural component of neuronal membranes and supports the same cognitive/neuroprotective goals.
  • B-complex vitamins (B1, B6, B12)
    Support neurotransmitter synthesis and myelin health, reinforcing neuropeptide-based cognitive protocols.

⚠️ USE WITH CAUTION

  • Seizure disorders / epilepsy
    CNS-active peptide complexes with limited controlled human data warrant caution in seizure-prone individuals due to unknown excitability effects.
  • Other CNS stimulants or nootropics stacked aggressively
    Combining multiple neuroactive compounds increases risk of overstimulation, headache, or unpredictable interactions with little data to guide dosing.
  • Pregnancy/breastfeeding
    No human safety data exists for this bovine-derived neuropeptide complex in pregnancy.

📋 IMPORTANT NOTES

  • ⏰ Optimal timing: Morning IM injection (before 3 p.m.). A second dose, if prescribed, no later than mid-afternoon to avoid agitation/sleep disturbance.
  • Cortexin is a bovine/porcine cerebral-cortex neuropeptide complex: IM only; not for IV self-administration.
  • Diabetes note: No significant acute blood-glucose lowering effect; not a glucose-control agent.
  • Reconstitute slowly, swirl (do not shake); rotate IM sites if repeat injections needed.
  • Transient headache or dizziness may occur in first 1–4 injections: rest and hydrate; avoid driving 2–4 h post-injection.
  • Space other peptide/supplement injections 15–30 minutes when stacking.
