What dose are you on? (self-reported, unverified)

Read this first. These numbers come from anonymous visitors typing in a box. Nobody checks them. People misjudge, mistype, troll, or take untested products of unknown strength. They are not a dose guide and never override the sourced table above. They exist only so the sourced ranges can be compared with what people say they take. If you are deciding what to take, use the sourced table, start low, and read the risks section.

Mixing

For best safety practice, don't mix this drug with other depressants.

Why: respiratory depression. PsychonautWiki says:

“Respiratory depression (also known as hypoventilation) can be described as a reduced urge to breathe that can be fatal depending on its intensity.” (PsychonautWiki, Respiratory depression, revision 150612)
“... otherwise safe dosages of these compounds can become fatal when combined with even small amounts of other classes of depressant. For example, benzodiazepines combined with opioids are an extremely common cause of fatal respiratory depression. It is therefore strongly discouraged to combine these depressants at any dosage range.” (PsychonautWiki, Respiratory depression, revision 150612)
“The most common cause of substance-related deaths is the combination of depressants (such as opiates, benzodiazepines, or alcohol) with other depressants.” (PsychonautWiki, Responsible drug use, revision 168206)
“This combination potentiates the muscle relaxation, amnesia, sedation, and respiratory depression caused by one another. At higher doses, it can lead to a sudden, unexpected loss of consciousness along with a dangerous amount of depressed respiration.” (PsychonautWiki, dangerous interactions table, "Depressants" row, revision 156847)
