Stress Reduction Peptides
Reduces stress and anxiety
Stress-reducing peptides target the neurochemical pathways that drive anxiety, cortisol overproduction, and the chronic stress response. Selank is the most studied, developed as a synthetic analog of tuftsin (an immune-modulating tetrapeptide) with pronounced anxiolytic effects. It modulates GABA, serotonin, and dopamine systems without causing sedation or dependence. Semax, while primarily a cognitive enhancer, also reduces stress by normalizing BDNF and modulating the HPA axis (the hormonal stress response system).
DSIP (delta sleep-inducing peptide) reduces stress indirectly by improving deep sleep, which is when cortisol levels naturally reset. BPC-157 has shown anxiolytic effects in animal models through its modulation of dopaminergic and serotonergic systems. These peptides offer a different approach to stress management than benzodiazepines or SSRIs: they address neurochemical imbalances without the sedation, cognitive blunting, or dependence risk associated with conventional anxiolytics.

Oxytocin
Oxytocin is a naturally occurring nine-amino-acid hormone produced in the brain, often called the "love hormone" for its role in social bonding and trust. It is FDA-approved for inducing labor and controlling postpartum bleeding, and is also being studied for autism, anxiety, and social disorders.
Selank
Selank is a synthetic seven-amino-acid peptide derived from the immune protein tuftsin, developed in Russia. Research shows it has both immune-supporting and anti-anxiety properties without causing sedation or dependence.
DSIP (Delta Sleep Inducing Peptide)
DSIP (Delta Sleep Inducing Peptide) is a naturally occurring brain peptide first isolated from rabbit brain tissue. Research focuses on sleep promotion, stress reduction, and hormone regulation. It shows complex effects that vary depending on the context.
PE-22-28
PE-22-28 is a synthetic seven-amino-acid peptide designed to block a specific potassium channel (TREK-1) in the brain. Research in animal models focuses on antidepressant-like effects and cognitive enhancement through brain growth factor support and increased brain cell adaptability.
