Cerebroprotein Hydrolysate_Dosage, benefits & legal status
Also known as cerebroprotein hydrolysate I, brain protein hydrolysate
A generic name for pig-brain peptide mixtures, sometimes including Cerebrolysin itself.
What is Cerebroprotein Hydrolysate?
Plain language first. The technical label stays, but it never stands alone.Overview
A pig-brain peptide mixture sold under a generic name. Hospital versions exist in India and China, and the powder vendors sell is a different product of unpublished composition.
Cerebroprotein hydrolysate describes enzymatic hydrolysates of lipid-free porcine brain protein, containing low molecular weight peptides and free amino acids. The term covers several distinct preparations from different manufacturers, including injections used in Indian and Chinese hospitals and cerebroprotein hydrolysate I, and in Chinese-language usage it is also applied to Cerebrolysin. Composition varies with tissue, enzymes and process, and no preparation is standardized to a single active molecule.
What it's used for
Given in hospitals in India and China as an add-on for stroke, head injury and dementia. Sold by peptide vendors as a small vial of powder.
How does Cerebroprotein Hydrolysate work?
What it does in the body, and where.Cerebroprotein hydrolysate is made rather than synthesized, which is why it cannot be pinned to one formula.
- 01Pig brain protein is broken down with enzymesFat is removed and the protein is cut into small peptides and free amino acids. What comes out depends on the tissue, the enzymes and the process, so each maker's product differs.
- 02The proposed action is neurotrophicThe idea, shared with Cerebrolysin, is that some fragments act like the growth factors that keep nerve cells alive. Animal studies support parts of this, but no single active molecule has been identified.
- 03The name is used looselyChinese papers apply it to Cerebrolysin as well as to other brain hydrolysates, and one Chinese meta-analysis translates it as Cerebrolysin in its English abstract. When you read a study, check which product it tested.
- 04Hospital trials test hospital productsThe human evidence comes from infusions of manufactured medicines of known strength. None of it describes a vendor's research powder.
What else is it used for?
Each group carries its own evidence level.Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.
Stroke
Clinical use- ReviewA 2017 Chinese meta-analysis pooled 20 randomized trials with 3,313 patients given it on top of standard care for acute ischemic stroke. Neurological and daily-living scores improved, while death, disability and adverse reactions did not differ.
- ReviewThe review's English abstract calls the product Cerebrolysin, which shows how loosely the two names are used.
Young children with developmental delay
Early research- Human trial102 children under three had rehabilitation, and the treatment group also received 14 days of infusions followed by oral derivatives. At 90 days that group had improved more on fine motor and adaptive skills. Adverse events occurred in 55.3% against 47.7%, and none were serious.
Safety
Clinical use- Human observationCase reports describe allergic reactions in patients with traumatic brain injury and a whole-body inflammatory response in a stroke patient after hospital injections.
Vendor descriptions often borrow Cerebrolysin's trial record for this product, and some papers really do use the two names for the same thing. That does not make a vendor's vial equivalent to either. The hospital trials tested manufactured medicines of known strength, given as infusions, while a small vial of research powder is a different product whose composition nobody has published.

Half-life
Not a single number
How much, and do you cycle it?
The range, and whether you take breaks.10 up to 60 mg per day, short daily runs in reports. Hospital courses of daily infusions Trial dose
Human use comes in courses. The Chinese study in young children gave 14 days of daily infusions, then switched to oral derivatives for the rest of 90 days. No course has been studied for a vendor's product.
Not a single numberNo figure
A mixture of many fragments rather than one molecule, so a single half-life would not mean much.
You can compare this against the whole library to see where it sits.
How do I dose and price it?
Enter your vial and your dose. Pick a mix. We show the draw and the cost.The vial holds a fixed amount of drug. Adding more water does not make more drug, it just spreads it thinner, so you draw a bigger number on the syringe for the same dose.
Three firsthand reports describe powdered products at 10 to 60 mg a day. One explicitly describes intramuscular injections at 20 mg for days one through three, then 10 mg per injection for days four through seven; the 30 mg and 30-to-60 mg reports do not independently establish an injection route. These products are not verified as equivalent to manufactured Cerebrolysin. This is reported practice, not a recommendation; hospital doses cannot be transferred to research powder.
Clinical reference (separate from community reports): Human study dosing is product-specific. One cerebroprotein hydrolysate I study used 12–24 mg IV once daily for 14 days in young children, depending on age. These doses apply to that manufactured hospital product and cannot be transferred to research-vendor powder.

How do you store it?
Before mixing, and after.Follow the storage on the product label.
Cerebroprotein Hydrolysate is supplied as a finished product, so its label sets the storage. Pens, prefilled syringes, implants, tablets and ready-made solutions are used as supplied. Kits that include a powder are mixed just before the dose and usually used straight away, not kept for weeks. Many injectable products go in the fridge and must not be frozen, while others are kept at room temperature, so check the pack or ask the pharmacist.
