Description
DSIP 10mg — Product Identity and Format
Each vial supplied by Core Research contains 10mg of DSIP, verified by RP-HPLC to ≥99.0% purity with identity confirmed by ESI-MS. Batch-specific analytical documentation is available through the Core Research CoA Portal.
Evidence uncertainty notice: DSIP is a high-uncertainty research compound. A major review of DSIP research has explicitly described the sleep-factor hypothesis as inconsistent with the available evidence.
