Overview
Cerebrolysin is a porcine brain-derived peptide preparation containing low-molecular-weight neuropeptides and free amino acids. The compound “crosses the blood–brain barrier to support neuronal survival” and mimics endogenous neurotrophic factors like NGF and BDNF while modulating neuroinflammatory mediators.
Quick Start Summary
– Reconstitution: Add 3.0 mL bacteriostatic water to create a 20 mg/mL concentration
– Daily dosing range: 20–32 mg once or twice daily via subcutaneous injection
– Easy measurement: At 20 mg/mL concentration, 1 insulin unit = 0.2 mg
– Storage (lyophilized): Room temperature ≤25°C (≤77°F)
– Storage (reconstituted): Refrigerate at 2–8°C; use within 7 days; do not freeze
Dosing Protocol
Standard Gradual Titration (8+ weeks)
| Week | Daily Dose | Injection Method |
|---|---|---|
| 1 | 20 mg | 100 units (1.0 mL) × 1 daily |
| 2 | 24 mg | 60 units AM + 60 units PM |
| 3 | 28 mg | 70 units AM + 70 units PM |
| 4+ | 32 mg | 80 units AM + 80 units PM |
Guidelines:
– Increase by approximately 4 mg weekly as tolerated
– Split doses exceeding 100 units into separate AM/PM administrations
– Rotate injection sites (abdomen, thighs, upper arms)
– Typical cycle length: 8–12 weeks; optional extension to 16 weeks
Reconstitution Steps
1. Draw 3.0 mL bacteriostatic water with sterile syringe
2. Inject slowly down vial wall; avoid foaming
3. Gently swirl/roll until dissolved (do not shake)
4. Label and refrigerate at 2–8°C protected from light
5. Use within 7 days of reconstitution
Supplies Needed (8-Week Protocol Example)
– Cerebrolysin vials (60 mg): ~26 vials
– Insulin syringes (U-100): ~105 syringes
– Bacteriostatic water: 78 mL (~8 bottles of 10 mL)
– Alcohol swabs: ~210 swabs (3 × 100-count boxes)
How It Works
Cerebrolysin contains biologically active compounds with molecular weights below 10 kDa, allowing blood-brain barrier penetration. Preclinical studies demonstrate “neuroprotective effects including reduced infarct size and improved recovery in ischemia models.” The preparation exerts neurotrophic activity comparable to endogenous growth factors.
Potential Benefits
– Neuroprotection and neuronal survival support
– Preclinical models show reduced neuronal damage after ischemic insult
– Human dementia trials suggest modest cognitive benefits with IV infusions
– Generally well-tolerated in short-term use
Possible Side Effects
– Mild injection-site reactions (redness, local discomfort)
– Rare reports of dizziness, headache, or gastrointestinal upset
– Discontinue and consult healthcare provider if significant adverse effects occur
Injection Technique
– Clean vial stopper and skin with alcohol; allow to dry
– Pinch a 2–4 cm skinfold; insert needle at 45–90° angle into subcutaneous tissue
– Do not aspirate for subcutaneous injections
– Inject slowly and steadily
– Rotate sites systematically to avoid lipohypertrophy
– Use different sites for split AM/PM doses
Lifestyle Considerations
– Maintain nutrient-dense diet rich in omega-3 fatty acids, antioxidants, and B-vitamins
– Engage in regular aerobic exercise and cognitive stimulation
– Prioritize 7–9 hours of quality sleep
– Minimize stress and avoid neurotoxic substances
Storage Requirements
Lyophilized state:
– Controlled room temperature ≤25°C
– Dry, dark conditions
– Do not freeze
After reconstitution:
– Refrigerate at 2–8°C (35.6–46.4°F)
– Use within 7 days
– Protect from light
– Allow vials to reach room temperature before opening to minimize condensation
Important Notes
– Use new sterile insulin syringes each time
– Dispose of syringes in a sharps container
– Document daily dose, timing, and injection site for consistency
– For doses exceeding 100 units (1.0 mL), split into two separate injections
