Cerebrolysin (60 mg vial)
Once to twice daily subcutaneous protocol for cognitive and neurological research.
Cerebrolysin is a porcine-derived mixture of low-molecular-weight neuropeptides with genuine clinical history in stroke and dementia care in parts of Europe and Asia. The protocol below reflects the injected course format used in that literature.
Quick answer: at the standard 60 mg + 3 mL reconstitution, a 32 mg split AM/PM dose of Cerebrolysin draws 80 units (0.8 mL) x2 on a U-100 insulin syringe, once to twice daily subcutaneous.
Protocol overview
Dosing & reconstitution
Frequency: Once to twice daily subcutaneous
Typical duration: 8-12 weeks
Reconstitution: 60 mg vial + 3 mL bacteriostatic water = 20 mg/mL. Units below are for a U-100 insulin syringe at this concentration.
| Phase | Dose | Units per injection |
|---|---|---|
| Week 1 | 20 mg once daily | 100 units (1.0 mL) |
| Week 2 | 24 mg split AM/PM | 60 units (0.6 mL) x2 |
| Week 3 | 28 mg split AM/PM | 70 units (0.7 mL) x2 |
| Week 4+ | 32 mg split AM/PM | 80 units (0.8 mL) x2 |
Units = (dose ÷ concentration) × 100 on a U-100 syringe. Change the vial size or water volume and the calculator redoes all of this for you.

Cerebrolysin dosing schedule
Cerebrolysin is an approved medicine in a number of countries in Europe and Asia, and has been studied in sizeable stroke, traumatic brain injury and dementia trials. Efficacy remains contested — Cochrane reviews of the stroke evidence have not found convincing benefit — but the dosing itself is well documented.
| Phase | Amount | Frequency | Notes |
|---|---|---|---|
| Acute stroke trials | 30 mL | Once daily, intravenous infusion | A commonly used trial amount, given over a course of consecutive days. |
| Higher trial arms | 50 mL | Once daily, intravenous infusion | Used in some traumatic brain injury and stroke protocols. |
| Lower / maintenance arms | 10 mL | Daily, intramuscular or intravenous | Appears in dementia and milder-indication protocols. |
Study length: Courses of 10–21 consecutive days are the norm across the trial literature.
Reconstitution and measurement
This part is arithmetic and does not depend on the evidence level. Concentration is vial size divided by the bacteriostatic water you add. Draw volume is your target amount divided by that concentration. Units are draw volume times 100, because a U-100 syringe reads 100 units per millilitre. Common vials for Cerebrolysin: Not stocked by our featured supplier.
- Wipe the stoppers of both vials with an alcohol swab and let them dry.
- Draw the bacteriostatic water with a sterile syringe and inject it slowly down the inside wall of the peptide vial — never straight onto the powder.
- Swirl gently until the solution is clear. Do not shake; foaming and agitation damage peptides.
- Label the vial with the date and concentration, and refrigerate at 2–8 °C protected from light.
Storage and stability
Supplies math
Whatever amounts your research uses, the planning arithmetic is the same. The calculator runs all of this per compound.
Supplies by protocol length
Based on the maintenance dose above (32 mg split AM/PM, once to twice daily subcutaneous) and a 60 mg vial reconstituted with 3 mL.
| Duration | Injections | Vials | Syringes | Bac water | Swabs |
|---|---|---|---|---|---|
| 8 weeks | 112 | 112 x 60 mg | 124 | 34 x 10 mL | 224 |
| 12 weeks | 168 | 168 x 60 mg | 185 | 51 x 10 mL | 336 |
| 16 weeks | 224 | 224 x 60 mg | 247 | 68 x 10 mL | 448 |
Syringe count includes ~10% spares. Swabs = 2 per injection (stopper + site). Vial count assumes the full maintenance dose for the entire duration.
Important notes
Practical considerations for consistency and safety.
- Use a new sterile insulin syringe for each injection and dispose in a proper sharps container.
- Rotate intramuscular injection sites (deltoid, vastus lateralis, gluteus medius) and use the appropriate needle gauge for the muscle.
- Inject slowly and steadily; wait a few seconds before withdrawing the needle to ensure complete delivery.
- Administer at the same time each day for consistent levels. Setting a daily reminder helps maintain the schedule.
- The 60 mg vial size is standard for this compound. Reconstitute with 3 mL bacteriostatic water for a convenient concentration.
How Cerebrolysin works
Not a single peptide but a standardised mixture of low-molecular-weight peptides and amino acids produced by enzymatic breakdown of purified porcine brain protein. Its proposed action is neurotrophic, resembling endogenous growth factors.
Benefits & side effects
Potential benefits
- Neuropeptide mixture with neurotrophic activity
- Supports cognitive function in clinical research
- Used clinically in some countries for neurological conditions
- Promotes neuroplasticity in research models
Possible side effects
- Injection site reactions
- Headache and dizziness reported
- Higher doses split to reduce peak effects
- Monitor liver function
This list reflects published literature and community reports. Individual responses vary. Not medical advice.
Bloodwork worth tracking
The community-standard practice is a baseline panel before starting, a recheck 8 to 12 weeks in, and another after time off. For Cerebrolysin, the markers most worth watching:
CMPCBCliver panel
Typical time off: 4-8 wks
Lab panels are how a research protocol stays honest: numbers move before symptoms do. Interpretation belongs with a clinician. Not medical advice.
Lifestyle factors
None of the literature above was run on a background of poor sleep and no protein. These variables move outcomes more reliably than any compound on this site.
- Protein in the 1.6 to 2.2 g/kg range preserves lean mass through any body-composition phase.
- Resistance training 2 to 4 days per week plus 150+ minutes of weekly aerobic work reinforces whatever the protocol is doing.
- Sleep is the recovery window: 7 to 9 hours at consistent times.
- Hydration matters more than usual on compounds with GI or flushing effects: 2 to 3 liters daily.
- Track the variables that matter: weigh-ins, measurements, photos, and labs at sensible intervals.
Subcutaneous technique and practical notes
General best practice from clinical injection guidance — the same fundamentals nurses are taught, none of it specific to any compound.

Quick answers
How many syringe units is a 32 mg split AM/PM dose of Cerebrolysin?
At the standard reconstitution of 60 mg with 3 mL bacteriostatic water (20 mg/mL), a 32 mg split AM/PM dose draws 80 units (0.8 mL) x2 on a U-100 insulin syringe.
How do you reconstitute Cerebrolysin?
Add 3 mL of bacteriostatic water to the 60 mg vial for 20 mg/mL. Inject the water slowly down the inside wall of the vial, swirl gently without shaking, and refrigerate at 2 to 8 °C after mixing.
How long does a 60 mg vial of Cerebrolysin last?
About 1 maintenance doses of 32 mg split AM/PM, roughly 0.1 weeks at once to twice daily subcutaneous.
Does Cerebrolysin have human trial data?
Yes. The dosing on this page is anchored to published human research (Cerebrolysin clinical trial literature in acute ischaemic stroke and vascular dementia).
How does Cerebrolysin work?
