PE-22-28 is a synthetic heptapeptide (mini-spadin) designed for research into brain health, mood regulation, and cognitive support.

• It consists of seven amino acids with the sequence GVSWGLR, making it a shortened, more stable version of the natural spadin protein.
• Researchers study it primarily as a selective TREK-1 potassium channel inhibitor, which helps regulate neuronal excitability.
• We supply PE-22-28 as high-purity lyophilized powder (≥98% by HPLC) for accurate laboratory and research use.
• Its small size and optimized structure give it better stability and potential potency compared to the full spadin protein.
• PE-22-28 is one of the newer research peptides gaining attention for fast-acting effects on mood and neuroplasticity pathways.
• We ensure every batch is lab-tested so researchers receive consistent, reliable product for their studies.

 PE-22-28 works by selectively blocking TREK-1 potassium channels in the brain, which can increase neuronal activity linked to mood and cognition.

• This blockade reduces potassium outflow, helping depolarize certain neurons and boost serotonin neuron firing.
• Research shows it may enhance brain-derived neurotrophic factor (BDNF) levels, supporting neuroplasticity and new neuron growth.
• Unlike broad-acting compounds, it targets a specific channel, potentially leading to fewer off-target effects in studies.
• We provide this peptide so researchers can explore its unique mechanism in mood regulation and neuroprotection models.
• Animal studies indicate effects can appear rapidly, sometimes within days, due to direct channel interaction.
• Proper reconstitution and handling help maintain its activity for accurate experimental results.

 The main researched benefits of PE-22-28 focus on rapid mood support, enhanced brain plasticity, and cognitive improvement.

• Studies explore its potential to lift mood faster than many traditional options by modulating TREK-1 channels.
• It shows promise for promoting neurogenesis, particularly in the hippocampus area important for memory and emotions.
• Researchers investigate its role in neuroprotection, helping brain cells resist stress and damage.
• Potential cognitive benefits include better memory formation and learning capacity in preclinical models.
• Some research points to possible anxiety-reducing effects through improved mood regulation pathways.
• We offer PE-22-28 so scientists can continue exploring these benefits in controlled research settings.
• Its high purity and stability make it ideal for repeatable, high-quality experimental outcomes

 Yes, PE-22-28 often demonstrates faster-acting effects in research models, with potential benefits appearing in just a few days.
