DOSINA

A-PIHP

Stimulant

Quite new Pyrrolidine based stimulant of the cathinone class. Not very many reports. Probably has a very fast tolerance raise, and lack of effects over time.

Harm reduction

  • Test your substance. Cocaine, amphetamine and MDMA powders are routinely cut with fentanyl or nitazenes, and stimulant pills are frequently counterfeits.
  • Do not mix stimulants with each other, with alcohol, or with MAOIs, SSRIs or tramadol - the cardiovascular and serotonin risks compound.
  • Watch body temperature. Overheating and dehydration cause more stimulant emergencies than heart attacks do. Take breaks, cool down with water and air, and sip (do not gulp) fluids.
  • Eat and sleep. Sleep deprivation plus stimulants is the standard route into stimulant psychosis.
  • Do not re-dose compulsively. Set a maximum before you start, and give it to someone else to hold you to.
  • Chest pain, severe headache, one-sided weakness, slurred speech or fainting are medical emergencies. Call for help immediately.
  • Nasal use damages the septum and sinuses; chronic use causes permanent damage that does not heal.
