I tried this via vaporizer, about .25 to .45 gram and it fucking rocked my brain.
It started with a general brain fog and blossomed to a full on smashed head. It made me feel like I just woke up at the dentist -- my face felt numb.
It also made my heart race, so if you're prone to tachycardia, take this one in small steps.
My limbs felt pleasantly tingly at first, and then, swear to god, they started flexing and contracting almost seizure-like. That wasn't as pleasant. I am prone to atypical reactions, so my brain chemistry may be a bit unique... YMMV.
Very strong, very quick effects. Recommended for pros, recommended in very small amounts for newbies.
