Cerebrolysin Protocol Guide
Cerebrolysin is a brain-derived peptide preparation containing low-molecular-weight neuropeptides and free amino acids obtained from purified porcine brain tissue. Approved as a pharmaceutical in over 40 countries for stroke recovery, traumatic brain injury, and dementia, it contains neurotrophic factors that mimic BDNF, GDNF, NGF, and CNTF. Cerebrolysin is one of the most clinically studied neuroprotective agents with over 200 clinical trials. This protocol covers administration from a 10mL pre-mixed solution via intramuscular injection at 5mL daily in 10-20 day cycles, and neuroprotective stacking.
Protocol Overview
- Compound
- Cerebrolysin (Standardized porcine brain protein hydrolysate — peptide complex)
- Category
- Neurotrophic Complex / Neuroprotective
- Mechanism
- Contains BDNF, NGF, CNTF, and other neurotrophic factors; promotes neuronal survival, synaptogenesis, and neuroprotection
- Structure
- Low-molecular-weight neuropeptides and free amino acids from purified porcine brain tissue
- Half-Life
- ~hours (peptide mixture, bioactive components)
- Vial Size
- 10mL pre-mixed ampule (215.2 mg/mL, pharmaceutical grade)
- Reconstitution
- None required — pre-mixed solution, draw directly from ampule
- Route
- Intramuscular (IM) injection or slow IV infusion (clinical settings only)
- Frequency
- Daily × 10–20 days per cycle (Khavinson protocol)
- Cycle Length
- 10–20 days on, 2–3 months off; 2–3 cycles per year
Dosing Protocol
| Protocol | Dose | Frequency | Route | Duration |
|---|---|---|---|---|
| Standard | 5mL | Once daily | Intramuscular (IM) | 10-20 day cycle |
| Intensive | 10mL | Once daily | Intramuscular (IM) | 10-20 day cycle |
Cycling: 10-20 days on, followed by 2-3 months off. Repeat 2-3 cycles per year. For volumes above 5mL, consider splitting between two injection sites.
Administration — No Reconstitution Needed
Cerebrolysin comes as a pre-mixed solution in ampules. No reconstitution required. Draw directly from ampule.
Materials Needed
- Cerebrolysin 10mL ampule (pre-mixed solution)
- 3-5mL syringe with 21-23 gauge needle for drawing
- Injection needle (21-23 gauge, 1-1.5 inch for IM)
- Alcohol swabs
Step-by-Step Process
- Open the ampule by snapping the neck at the score mark
- Draw the desired volume (5mL standard, up to 10mL intensive) using a syringe
- Switch to a fresh injection needle
- Select IM injection site (deltoid, gluteal, or vastus lateralis)
- Clean injection site with alcohol swab and administer IM
- For volumes >5mL, split between two injection sites
| Volume | Protocol | Route |
|---|---|---|
| 1mL | Low / Starter | IM |
| 2mL | Conservative | IM |
| 5mL | Standard | IM |
| 10mL | Intensive | IM |
Administration Guide
IM Injection Sites
- Deltoid: Upper arm, alternate sides
- Gluteal: Upper outer quadrant
- Vastus lateralis: Outer mid-thigh
- For volumes >5mL, split dose between two sites
Timing & Storage
- Timing: Morning administration recommended
- Ampule duration: 1 ampule = 1-2 days at 5-10mL/day
- Storage: Room temperature, protect from light
- Do not use partially used ampules — discard remainder
Expected Timeline
Side Effects & Monitoring
Common Side Effects
- Injection site pain or irritation (IM)
- Dizziness or headache during initial days
- Mild nausea
- Fever (rare)
Cerebrolysin is an approved pharmaceutical in over 40 countries with extensive clinical trial data (200+ trials). Side effects are generally mild and transient.
Precautions
- Do not use in patients with epilepsy or severe renal impairment
- Caution in patients with allergic diathesis
- IM injection only — do not administer IV push (IV drip only in clinical settings)
- Not recommended during pregnancy or breastfeeding
- Monitor for hypersensitivity reactions
Stacking Recommendations
Compatible Compounds
- NAD+: Cellular energy support for neuronal metabolism
- Dihexa: HGF potentiator for synaptogenic synergy
- Semax: Complementary BDNF-pathway nootropic
- Selank: Anxiolytic support during cognitive enhancement
- BPC-157: Systemic repair and neuroprotective support
Popular Stacks
- Neurotrophic Stack: Cerebrolysin 5mL IM/day + Semax 600mcg/day intranasal
- Neuroprotective: Cerebrolysin 5mL IM/day + NAD+ IV/SubQ + BPC-157
- Cognitive Recovery: Cerebrolysin + Dihexa (oral) + Selank intranasal
Blood Work Recommendations
| Panel | Markers | Timing |
|---|---|---|
| Basic Panel | CBC, CMP | Baseline, Week 4 |
| Liver Function | ALT, AST, GGT | Baseline, Week 4 |
| Kidney | BUN, creatinine, eGFR | Baseline, Week 4 |
| Inflammatory | CRP, homocysteine | Baseline |
Monitoring is primarily precautionary given the limited human safety data. Track liver and kidney markers to ensure no organ stress from the compound.
