PE-22-28 (Myotropic) – Neuroprotective and Stress-Regulating Peptide for Laboratory Research

Myotrope 's PE-22-28 is a synthetic fragment of the galanin neuropeptide , developed for preclinical research into stress regulation, neuroprotection, cognitive performance, and pain modulation . By using a selective fragment of galanin, researchers can study the effects of this peptide on neural circuits, neurotransmitters, and mitochondrial health , without the complexity of the full galanin protein.

How does PE-22-28 work?

PE-22-28 is a fragment of the 30-amino acid galanin peptide (amino acids 22–28) and acts by interacting with galanin receptor subtypes (GALR1, GALR2, GALR3) :

• Neuroprotection: Supports neuronal stability and mitochondrial function, reduces excitotoxic stress
• Cognitive and emotional regulation: Fine-tuning of neurotransmitters such as serotonin, dopamine and norepinephrine
• Stress and mood: Possible improvement of stress adaptation and reduction of anxiety-like behaviors
• Pain modulation: Research models show effects on nociceptive pathways without classic opioid risks

All effects are research-based only and based on preclinical and laboratory studies .

Benefits of PE-22-28

• Supports research into stress resistance and mood
• Promotes cognitive performance and memory in preclinical models
• Potential for neuroprotection and mitochondrial support
• Supports studies of pain modulation without opioid risks
• Ideal for synergistic studies with other peptides such as BPC‑157 or Epitalon
• Buying from Myotrope guarantees research-grade purity and COA
• Relevant for preclinical research into anti-aging, focus, mental resilience and regenerative processes
