Side-by-side comparison of key properties, dosing, and research.

Recovery & Repair
BPC-157
Sleep OptimizationCognitive Enhancement
DSIP
Summary
BPC-157 is a synthetic pentadecapeptide derived from a protective protein found in the stomach. It is one of the most extensively researched healing peptides, known for accelerating tissue repair, reducing inflammation, and protecting the gastrointestinal tract.
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.
