Cerebrolysin vs PE-22-28

Research material comparison: purity standards, available formats, molecular data, batch COA documentation, and regulatory status. For in vitro research use only.

Cerebrolysin: CPE-22-28: D
AttributeCerebrolysinPE-22-28
CategoryNootropic / NeuroprotectiveNootropic / Neuroprotective
Evidence RatingC — Phase I–II Clinical TrialsD — Preclinical Only
Clinical StatusApproved as prescription drug in 50+ countries (Austria, Russia, China, South Korea, and others). Not FDA-approved. Over 150 clinical trials with >7,000 patients.Preclinical tool compound only. No clinical trials. No regulatory evaluation.
MechanismCerebrolysin provides multimodal neuroprotection through several pathways: it enhances neurogenesis and neuroplasticity via activation of PI3K/AKT and Sonic Hedgehog (Shh) signaling, promotes synaptic remodeling through CREB phosphorylation and BDNF-like activity, inhibits calpain-mediated neuronal ...PE-22-28 blocks the TREK-1 two-pore-domain potassium channel (KCNK2/K2P2.1), which is widely expressed in the brain. TREK-1 knockout mice display a depression-resistant phenotype, suggesting that TREK-1 blockade may have antidepressant effects. PE-22-28 is a more potent and shorter analog of spadin ...

WADA StatusNot ListedNot Listed
Research Half-LifeNot meaningfully defined for a multi-component preparationImproved over spadin in rodent work; not established in humans
Key Use Cases
  • Cognitive Enhancement
  • Antidepressant Research
  • Ion Channel Research
Safety Concerns
  • Generally well-tolerated in clinical trials
  • Common: dizziness, headache, injection site reactions
  • Rare: agitation, fever, flu-like symptoms
  • No human safety data exist
  • Mouse studies at antidepressant-effective doses did not report overt toxicity
  • TREK-1 channels are expressed in heart, vasculature, and GI tract — potential for off-target effects
Contraindications
  • Epilepsy or history of seizures
  • Severe renal impairment
  • Known allergy to porcine-derived products
  • Pregnancy and breastfeeding
  • Not for human use (research compound only)
  • No established contraindications due to absence of any clinical data
  • Theoretical cardiac risk due to TREK-1 expression in cardiomyocytes
Regulatory (US)Not FDA-approved. No IND application. Cannot be legally prescribed.Not FDA-evaluated. Research tool compound. Sold by some peptide suppliers as a research chemical.
