Cerebrolysin Dosage Chart & Schedule
A neurotrophic preparation of low-molecular-weight peptides and amino acids derived from porcine brain tissue, used in several countries for neurological conditions but not FDA-approved.
Cerebrolysin is a ready-to-use solution measured in milliliters, not reconstituted from powder or dosed in units. In the countries where it is used (it is not FDA-approved), courses run roughly 5-30 mL per day over 10-20 days - IM for small volumes, IV infusion for larger ones.
Figures describe how Cerebrolysin is reported in the research literature and research-community references — not a recommendation for human use. For laboratory research only.

- Once daily
- Weekly total
- ~140-210 mL/week

- Acute-setting courses in stroke/TBI studies
Upper range used in acute neurological studies.
Dosed in milliliters, not units
- Cerebrolysin is a mixture of low-molecular-weight peptides and amino acids, not a single molecule.
- It is supplied as a ready-to-use sterile solution and measured in mL of that solution.
- The U-100 'unit' math and mcg-per-injection conversions used for lyophilized peptides do not apply.
Course-based, not continuous
- Clinical use where it is marketed is structured as repeated 10-20 day courses.
- Small volumes are given intramuscularly; larger volumes are diluted and infused intravenously.
Ready to run this protocol?
Dosing is only as good as the vial. Research-grade peptides are third-party tested with published COAs from our top-rated source — reconstitute with confidence and skip the guesswork on identity and purity.
Weekly schedule
A typical week on the standard course protocol (Once daily).
Dosing day Off
From vial to injection in 6 steps
Wipe both vial tops
Swab the peptide vial and the bacteriostatic-water vial with fresh alcohol and let them dry.
Draw the water
Pull the planned amount of bacteriostatic water (per your mix) into the syringe.
Add it slowly
Run the water down the inside wall of the vial — don't blast the powder. Swirl gently; never shake.
Let it dissolve
Wait until the solution is fully clear, then refrigerate the vial.
Draw your dose
Pull the calculated units on a U-100 insulin syringe.
Store between uses
Keep the reconstituted vial refrigerated and use within its stable window.
Handling & storage
- Supplied as a sterile ready-to-use solution - not reconstituted from a lyophilized powder.
- Volumes above roughly 5 mL are typically diluted and given as a slow IV infusion in the studies.
- Store refrigerated and protect from light per the commercial preparation.
- Not FDA-approved; it is a biological mixture rather than a single defined peptide.
Cerebrolysin dosing FAQ
Why is Cerebrolysin measured in mL instead of mcg or units?
Because it is a mixture rather than one molecule, it is standardized and dosed by volume of the ready-to-use solution. There is no single mcg-per-dose or U-100 unit conversion the way there is for a lyophilized peptide.
How long is a typical course?
Studies and clinical use in the countries where it is marketed generally run 10-20 consecutive days, with courses repeated periodically rather than dosed continuously year-round.
Is it injected IM or IV?
Both are described: smaller daily volumes (around 5-10 mL) are given intramuscularly, while larger volumes (up to ~30 mL) are diluted and delivered by slow IV infusion.
Can it be reconstituted with bacteriostatic water like other peptides?
No. It already comes as a liquid and is diluted for infusion, not mixed from powder, so the reconstitution calculator does not apply to Cerebrolysin.
