Id avoid it as the urge to redose approaches that of crack (or cocaine, depending on the ROA) but the comedown is worse and more protracted (the residual stimulation can last 12 hours easily when dosed high enough).
I did enjoy it a fair amount though, talk of it brings back the smell and taste (sort of bleach like).
It's novel, but mostly garbage as negrogesic mentions. I've tried it at 20 mg a few times, it's stimulating, but ruins your nose. Never tried high enough doses of it to compare it to 3-FPM. Now that stuff is a dangerously good time, and fairly forgiving in my experience.
And the smell of the stuff was the most offputting aspect of it to me TBH. I love the sinus burn of 3-FPM, call me crazy but it's a welcome sensation.
