Liraglutide
Sleep OptimizationCognitive Enhancement
DSIP
Summary
Liraglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and chronic weight management (Saxenda). It reduces appetite, slows gastric emptying, improves insulin secretion, and promotes weight loss of 5–10% in clinical trials.
DSIP is an endogenous neuropeptide originally isolated from rabbit cerebrospinal fluid that induces delta-wave (deep) sleep. It also modulates stress response, cortisol regulation, and LH secretion, making it valuable for sleep optimization and stress management.
Half-Life
~13 hours (once-daily dosing)
~30–60 minutes; however downstream sleep effects last 4–6 hours
Admin Route
