Cerebrolysin Dosage Calculator & Chart

1Set Up Your Mix

20 mg/mL · 20000 mcg/mL

1. Pick your peptide

2. How much peptide is in the vial? It's printed on the label — usually something like 5 mg

3. How much water are you adding? More water makes each dose easier to measure

4. How much do you want per dose?

Your Answer — Cerebrolysin

60 mg in 3 mL

1That's This Many mL

3Doses In The Vial

60 mg ÷ 3 mL = 20 mg/mL → 20 mg ÷ 20 mg/mL = 1 mL → × 100 = 100 units

Looks good. Draw to 100 units on a 1 mL syringe. That is an easy amount to measure, and this vial gives you 3 doses.

When to dose

Time of dayMorning and evening once the dose is split.

FoodWith or without food.

The protocol on this page is one injection in week 1 and two a day from week 2, so the timing follows the schedule rather than a fixed hour.

Where this plan came from

A published protocol

Where this came from: OptimalDosages protocol. Written for a 60 mg vial in 3 mL, which gives 20 mg/mL. The daily total goes up every week. Week 1 is one injection of 20 mg; from week 2 the day is split into a morning and an evening injection, so the amount in the Dose column is what goes in each syringe, not the whole day. Change the water figure and every number recalculates.

Common Questions — Cerebrolysin

How much bacteriostatic water do I add to a 60 mg vial of Cerebrolysin?

Adding 3 mL of bacteriostatic water to a 60 mg vial gives 20 mg/mL. That is the mix every number on this page is worked out from — change the water figure in the calculator and all the draw amounts update.

How many units on the syringe is a 20 mg dose of Cerebrolysin?

At 20 mg/mL, a 20 mg dose is 100 units on a 1 mL U-100 insulin syringe. One vial at that mix gives about 3 doses.

How strong is the evidence behind these Cerebrolysin doses?

Cerebrolysin is graded clinical. Human trial or approved-label dosing has been published for this compound. We grade every compound on this site so you can weigh the numbers accordingly — the full method is on our editorial policy page.
