What this score is: a measure of how much research exists and how far along it is (animal-only vs. human trials, research-stage vs. FDA approved) — not how safe, effective, or worth trying a compound is. A low score usually means “early stage” or “understudied,” not “bad.” A high score doesn’t mean “better” for your goals than a lower-scored one.
This is not my personal rating of the compound, not a recommendation, and not medical advice. It’s a general research synthesis for informational purposes only, not a live literature count. See the linked research and talk to a licensed clinician before making decisions based on it.
Mechanism
DSIP was originally isolated from rabbit brain in the 1970s and named for association with delta-wave (deep) sleep in early animal studies, though subsequent human research has produced inconsistent results and its mechanism is not well characterized. It is sold as a research chemical with limited modern clinical validation.
