    Dosing Protocols

    Beginner

    Beginner protocol

    • Dose: 5 mL/day IM (Cerebrolysin is a 215.2 mg/mL concentrate, so one 5 mL ampoule delivers ~1,076 mg of peptide/amino-acid solids - the 215.2 mg/mL figure is the concentration, not the dose)
    • Route: Intramuscular injection (IM); 5 mL is the maximum volume given by a single IM injection per the label
    • Frequency: Once daily, AM
    • Duration: 10-day cycles
    • Use case: First-time users; cognitive-enhancement research; mild cognitive complaints
    Standard

    Intermediate protocol

    • Dose: 10 mL/day (~2,152 mg)
    • Route: Per the manufacturer's label, 10 mL should be given as a slow IV injection - not as a single IM shot. If IM must be used, the dose has to be split across multiple sites (about 5 mL maximum per site). Doses of 10 mL and above are conventionally given intravenously.
    • Frequency: Once daily
    • Duration: 14-21 day cycles, repeat every 2-3 months
    • Use case: Post-concussion recovery research; cognitive-optimization protocols
    Advanced

    Advanced protocol

    • Dose: 20-30ml/day IV (slow infusion in saline)
    • Route: Intravenous (clinical setting only)
    • Frequency: Once daily
    • Duration: 10-21 day cycles
    • Use case: Acute neurological event recovery (clinical only); Alzheimer's research protocols

    Commonly Stacked With

    Pairs well with Semax and Selank for stacked neurotrophic + cognitive enhancement protocols. Often used as a foundational base for bioregulator peptide cycles. Avoid concurrent administration with MAOIs and SSRIs without clinician oversight.

    Side Effects & Safety

    Generally well-tolerated in clinical trials, with a safety profile comparable to placebo in most RCTs. The most common effect is an injection-site reaction (redness, pain, or burning). Other reported effects include dizziness or vertigo, headache, and - because of its mildly stimulating character - agitation, restlessness, or insomnia, especially with late-day dosing. Injecting too quickly can cause a transient feeling of heat, flushing, or sweating, so the dose should always be given slowly. Rare but serious: hypersensitivity and anaphylactoid reactions (rash, chills, breathlessness). Cochrane analysis of acute-stroke trials flagged a possible increase in non-fatal serious adverse events at the high 30 mL/day dose.

    Contraindications

    Do not use in: epilepsy or status epilepticus (may lower the seizure threshold), severe renal impairment, or known hypersensitivity to Cerebrolysin or any of its components. Avoid during pregnancy and breastfeeding (insufficient safety data). Give slowly and cautiously; the manufacturer's label warns against mixing it in the same infusion with balanced amino-acid solutions and against combining it with antidepressants or MAO inhibitors without medical supervision. Research use only in the US - not intended for human self-administration.

    Additional Notes

    Route depends on volume: up to 5 mL can be given IM; up to 10 mL by slow IV injection; and 10-50 mL should be diluted in saline and given as a slow IV infusion (15-60 minutes). Always administer slowly - rapid injection can cause a transient sensation of heat or flushing. Note that the 215.2 mg/mL figure is the concentration of the concentrate, not a dose (a 5 mL ampoule = ~1,076 mg). Research use only in the US; not for human use.
