The app keeps custom substances simple, so the full dose ranges live in the description text above. Ranges are harm-reduction guidance, not a prescription.

I've always wanted to try methaqualone. In Canada its only Schedule 3, so can still be RXed under the brand name, Sopor , but is often overlooked in the name of the allegedly less dangerous benzodiazepines.

Hey all, So i recently managed to get my grubby hands on some mmq. having drooled over qualuude reports in the past i was quite excited. Unfortunately, my scales were at a friends house and I was too keen to wait.
No pot in the house, dealer busted the day before, anxiety setting in. I'd had some Pentobarbital the night before to get to sleep but I was weary about taking that so soon. I dont want to rely on another thing like i rely on pot to go to sleep.
I recently aquired some methylmethaqualone from a trusted source and took it 3 nights in a row. 1st day: 60mg 60mg +30minutes Within 30 minutes of first dose felt happy and smiley, not too intense could have been attributed to placebo.
