- 0:40What Cerebrolysin isSteve describes it as a water-based mixture of brain-derived peptides and free amino acids. He says it is not suitable for people whose religion forbids pork.
- 2:40Composition and blood-brain barrierSteve says Cerebrolysin contains no BDNF, GDNF, NGF or CNTF. He argues those proteins are too large to cross the blood-brain barrier anyway, and he lists the peptide fragments found in two analyses.
- 15:43Effects on neurotrophic factorsSteve reviews human serum data and preclinical results on BDNF, GDNF, NGF, IGF-1 and TNF-alpha. He admits that his percentage estimates involve dubious extrapolation.
- 24:01Dose ranges from the evidenceSteve summarizes the doses behind these effects as 10 mL to 60 mL by intramuscular injection or infusion five times weekly, or 0.4 mL per kg of body weight intramuscularly each day.
- 26:21Pairing with DPP-4 inhibitorsSteve argues that DPP-4 enzymes break down several growth factors, so an inhibitor such as sitagliptin might add to the effect. He says there is no direct evidence for the combination and cites only his own experience.
- 35:01Approved uses and dosing in RussiaSteve lists the Russian uses for stroke, traumatic brain injury, vascular dementia and Alzheimer's disease, with doses of 10 mL to 50 mL. He contrasts the dosing guidelines with the lower starting doses in the product information.
- 40:13Evidence-based characteristicsSteve goes through the claimed effects, including stroke rehabilitation, cognition, depression, sleep, PTSD, smell loss and intranasal use. He calls much of the evidence inconclusive and flags retracted sleep-deprivation studies.
- 51:20Allergy and prion concernsSteve describes a stepwise allergy test starting with 0.1 mL subcutaneously and says to have epinephrine on hand. He says he found no evidence linking the product to prion disease, though any product of this kind of origin carries a theoretical risk.
- 56:37Cerebrolysin versus CortexinSteve compares the two using mostly Russian abstracts and says Cortexin looks better on cost and antioxidant effect. He estimates that 10 mg of Cortexin equals about 25 mL of Cerebrolysin.
- 1:09:50Steve's own experienceSteve reports feeling calmer and having less post-workout brain fog on 5 mL to 10 mL daily. He says some benefits lasted for months, though he was also taking fluvoxamine.
What the video says
Steve, who presents the VigorousSteve channel, gives a solo review of Cerebrolysin, a mixture of peptides and free amino acids that he says is extracted from brain tissue. He opens by noting that he found no scientific evidence for several uses popular among healthy people, such as athletic recovery, addiction or cognitive enhancement in people without dementia. He also says the product contains none of the neurotrophic factors it is often credited with.
The first half covers composition. Steve cites two analyses that identified 638 and 810 distinct peptides, with only a few fragments linked to possible anti-inflammatory, antioxidant or neuroprotective effects. He concludes that any benefit probably comes from the product acting as a secretagogue, meaning it prompts the brain to make its own neurotrophic factors. He then lists the effects he found on BDNF, GDNF, NGF, IGF-1 and TNF-alpha in human serum data and preclinical studies, and converts the preclinical doses to human equivalents. He gives a range of 10 mL to 60 mL by injection or infusion five times weekly, or 0.4 mL per kg of body weight intramuscularly each day. He also discusses pairing it with a DPP-4 inhibitor, with donepezil or CDP-choline, and describes the Russian medical uses and dosing.
The middle sections go through the evidence he found for stroke, brain injury, dementia, sleep, post-COVID smell loss and intranasal use. Steve flags that much of the sleep deprivation work comes from a researcher whose studies were retracted. He then sets out route-of-administration guidance, a step-by-step allergy test, and prion concerns. He says he found no evidence linking the product to prion disease but notes a theoretical risk with any product of this kind of origin. A comparison with Cortexin, a calf-derived product, draws mostly on Russian abstracts.
The last part is personal. Steve describes sleepiness, calmer mood and less post-workout brain fog from 5 mL to 10 mL doses over about 60 days, and says he saw no effect from Cerebrolysin before trying Cortexin. He closes by pointing to two critical articles and admitting the evidence is inconclusive. The video also carries sponsor and supplement promotion.
On each compound
Cerebrolysin2:40
Steve says Cerebrolysin is a brain-derived peptide and free amino acid mixture with no neurotrophic factors in it. He thinks it works by prompting the brain to make its own, and he reviews dosing, Russian medical uses, allergy and prion concerns, and his own experience.
See how your DNA reads CerebrolysinWhat this video doesn’t settle
- Steve says the composition evidence is thin, with only three of 810 identified peptides linked to possible neuroprotective effects.
- The BDNF percentage increases are his own extrapolations, including an assumed reference range because one study's baseline values were unknown.
- Most neurotrophic factor data come from preclinical studies, and he converted those doses to human equivalents himself.
Questions this video answers
Does Cerebrolysin contain BDNF or other neurotrophic factors?
Steve says it does not. He cites two analyses that found hundreds of peptide fragments but no BDNF, GDNF, NGF or CNTF. He argues instead that it may prompt the brain to produce its own.
What Cerebrolysin doses does Steve describe?
He describes a range of 10 mL to 60 mL by intramuscular injection or infusion five times weekly, or 0.4 mL per kg of body weight intramuscularly each day. He says he personally used 5 mL to 10 mL daily for about 60 days. These are his figures, not advice.
Does Steve think Cerebrolysin carries a prion disease risk?
Steve says he found no scientific evidence linking it to prion disease, including in the two composition analyses. He adds that any product of this kind of origin has a theoretical risk if not properly processed.
How does Steve say Cerebrolysin compares with Cortexin?
Based mostly on Russian abstracts, Steve says Cerebrolysin looked stronger for stroke and immune effects. Cortexin looked stronger on antioxidant activity and cost. He says he noticed no effect from his 60-day Cerebrolysin course but did notice one after switching to Cortexin.
How does Steve say to test for a Cerebrolysin allergy?
He suggests starting with 0.1 mL subcutaneously and waiting at least 24 hours. After that he suggests a small intramuscular dose, then a 1 mL intravenous test over five minutes, with epinephrine on standby. He notes the allergy is linked to the source of the product.
