Regulatory peptides studied for anxiolysis and stress-axis modulation.
A small set of regulatory peptides is studied for anxiolytic and mood-stabilizing effects, often with interest in achieving calm without the sedation, dependence, or cognitive dulling associated with classic GABAergic agents.
Investigated mechanisms include modulation of the stress (HPA) axis, neurotrophic support, and effects on serotonergic and GABAergic signaling. As with other neuroactive peptides, much of the human data is early-stage and concentrated in specific research traditions.
Synthetic heptapeptide analog of tuftsin investigated as an anxiolytic.
View profileEndogenous nonapeptide first isolated for its sleep-promoting properties.
View profileA 9-amino-acid cyclic hormone of labor and bonding — historically the first peptide hormone ever chemically synthesized, and the most over-marketed "love hormone."
View profileA few regulatory peptides are studied for anxiolytic and mood-stabilizing effects, often with the goal of calm without the sedation, dependence, or cognitive dulling of classic GABAergic agents.
Investigated mechanisms include modulation of the HPA (stress) axis, neurotrophic support, and effects on serotonergic and GABAergic signaling.
Much of the human data is early-stage and concentrated in specific research traditions, so findings should be treated as preliminary.
