Is DSIP safe?
Old IV studies; no repeated-use data
The old studies with DSIP by vein did not report side effects, but they were small and brief. The injectable DSIP sold online is unregulated. Its purity and sterility are unchecked. There is no safety data for repeated use under the skin. No one has studied interactions with sedatives. No one has studied effects in people with sleep apnea or mental illness. 267
The main documented risk is the unknown. There are no modern safety data, and online products are untested for purity. The early studies with DSIP by vein reported no side effects in small numbers of patients. 27
