What is the difference between DSIP and Cerebrolysin?

DSIP (Delta Sleep-Inducing Peptide) is graded C and is Not FDA-approved — research compound. Cerebrolysin (Cerebrolysin (porcine brain peptide complex)) is graded B and is Not FDA-approved in US — approved in 50+ countries for stroke, traumatic brain injury, and dementia. They are commonly compared because they share the categories: neuroprotection.

Which has stronger clinical evidence — DSIP or Cerebrolysin?

On our internal evidence scale, DSIP is C and Cerebrolysin is B. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of DSIP vs Cerebrolysin?

DSIP: 100–300 mcg before bed (subcutaneous). Cerebrolysin: Trial range: 5–30 mL daily (intravenous infusion). Always work with a licensed clinician — peptide dosing should be individualized.

DSIP vs Cerebrolysin

Both DSIP and Cerebrolysin are used for neuroprotection. Here's how their evidence, dosing, and regulatory status actually compare.

DSIP

Evidence C

Delta Sleep-Inducing Peptide

A nonapeptide originally isolated from rabbit blood after EEG-defined slow-wave sleep induction. Inconsistent human evidence for sleep but explored for stress and analgesia.

Cerebrolysin

Evidence B

Cerebrolysin (porcine brain peptide complex)

A standardized mixture of low-molecular-weight peptides from porcine brain. Decades of stroke, dementia, and TBI trial data — modest but consistent cognitive recovery effects.
