Cerebrolysin Composition: Peptides, Amino Acids & Research Specifications
Researchers evaluating Cerebrolysin composition should understand an important distinction: Cerebrolysin is not one defined peptide with one amino-acid sequence.

What Is Cerebrolysin Made Of?
The Peptides Lab US listing describes the preparation as approximately:
25% low-molecular-weight peptides below 10 kDa
and:
75% free amino acids
This makes composition an important consideration when comparing Cerebrolysin with individual research peptides.
What Does “Low-Molecular-Weight Peptides” Mean?
The product listing describes the peptide component as:
<10 kDa
The notation kDa refers to kilodaltons, a unit used when describing molecular mass.
This specification applies to the listed peptide fraction rather than establishing one molecular weight for Cerebrolysin as a whole.
Why Doesn’t Cerebrolysin Have One Peptide Sequence?
A defined peptide such as a tripeptide can be represented by one sequence.
Cerebrolysin is different because it contains a mixture of peptide components and amino acids.
Researchers therefore should not assign one peptide sequence to the complete preparation.
Composition vs Quantity
The product is listed as:
60mg
That is the labeled product quantity.
The listed:
~25% peptide / ~75% free amino-acid
description concerns composition.
These figures answer different questions.
Composition vs Purity
Composition should also remain separate from analytical purity.
For example:
25% / 75% = listed composition
while:
HPLC result = analytical characteristic under the applicable method and conditions
These numbers should not be substituted for each other.
Why Composition Matters When Comparing Prices
A Cerebrolysin price-per-milligram calculation refers to the labeled research preparation.
It should not automatically be presented as the price per milligram of a particular peptide component.
For the 60mg product:
Current price ÷ 60 = price per labeled mg of product
What Should Researchers Check?
Before procurement, review:
- Product identity
- Labeled quantity
- Product form
- Composition information
- Current price
- Availability
- Batch information
- Applicable analytical documentation
Avoid Oversimplified Product Claims
Descriptions such as:
“Cerebrolysin is a 60mg peptide”
can be misleading.
A more precise description is:
“A 60mg Cerebrolysin research preparation containing a mixture of low-molecular-weight peptides and free amino acids.”
