No legitimate or recommended dose — DSIP is an unapproved grey-market research chemical with no modern controlled human dosing data and no quality control. We do NOT provide a dosing protocol. The only human dosing on record is from small 1980s studies (e.g. subcutaneous or intravenous injections around 25 nmol/kg before sleep, given over repeated sessions), which is dated, was done under research/medical supervision, and does not constitute a validated protocol. DSIP is sold online almost exclusively as an injectable, which adds sterility and infection risk.
