[Help?!?!]

I've looked all around a and don't usually waste sites space making threads but after searching the B&D, I've found virtually nothing.

So what's up with the dosing of this, the effects, and the duration? I'll probably by IM'ing it, vaping it, etc.

From what I could find online (for insufflation):

Dosage: Low: 300ug Common: 600-900ug Strong: 900-1200ug.

Duration: 40-90 minutes.

I know it'd be hard to equate given unknown BA's, but what do you think IM doses might be like? I'll probably just vape small amounts until I'm satisfied. Where'd you gleam the data anyway?
