Why people use Cerebrolysin for Alzheimer's support

Parent showing memory loss. Cerebrolysin worth pursuing? The short answer: yes, this is one of the more-discussed uses for Cerebrolysin - but the evidence quality and the right protocol depend on what you're actually trying to fix.

This page covers what's known, what's not, and what the editorial take is for normal humans considering Cerebrolysin for Alzheimer's support.

What the evidence says

Evidence tier: Strong clinical. Multiple human studies support the dosing protocol; not yet FDA-labeled for this exact indication but close.

Multiple RCTs (Alvarez et al., 2011) showed cognitive improvement on standardized scales (ADAS-cog) in mild-to-moderate Alzheimer's.
Effect size is modest but consistent - similar to the FDA-approved cholinesterase inhibitors.
Sourcing in the US is the hard part - it is not FDA-approved and most US prescribers do not write for it.

Protocol notes

10-30mL IV infusion daily for 4 weeks, repeated every 3-6 months. Neurologist coordination essential.

Always with a sports-medicine doctor, telehealth provider, or specialist sign-off. Self-experimenting on injection schedules without clinical input is the most common way people waste money and get hurt.

How it's dosed (quick version)

Standard protocol is 10 to 30 milliliters (a small IV push or slow infusion) daily for 10 to 21 days, repeated every 3 to 6 months. Sourcing in the US is the real challenge - it is not FDA-approved here. Always with a doctor, ideally a neurologist or longevity-clinic prescriber.

Typical starting dose: 5 to 10 mL IV (intravenous, into a vein) on day 1 to test tolerance, then escalate to the full protocol dose.
Typical maintenance dose: 10 to 30 mL IV daily during the 10 to 21-day cycle. Stroke and TBI protocols use the higher end (20-30 mL); longevity protocols stay at 10-15 mL.
Frequency: Daily during the active cycle. Cycle repeated every 3 to 6 months.
Cycle length: 10 to 21 days of daily infusion. Stroke acute care often runs 21 days; maintenance protocols run 10 days.

What to skip

Vendors without a Certificate of Analysis (COA). Random gym-bro vendors with no third-party testing. The peptide market has a quality-control problem; the answer is COA per peptide, every time.
Pre-mixed blends from non-pharmacy sources. Compounding pharmacies that produce pre-mixed combinations with COAs are fine. Random vendor "stack vials" are not.
Massively over-dosed protocols. More is rarely better with peptides. Receptor saturation is real. Stick to evidence-based dosing.
