Hi all. Im new to posting here but not new to reading threads here. I read a ton in the past 4 years. Anyway, got a quick question and was thinking someone here has the answer. I purchased a few M Box 30s online and the seller promised they are pharm quality. Says they are not fent presses, which a lot of them are. Also, he has a ton of great feedback from buyers on how great these are. I got them today and been trying to sniff em. They burn my nose like a mother effa and clogged the hell out of it but it does however do something as i dont have any signs of withdrawal since these are the only things i have done all day. Has anybody had these or know what they might be ? I know it's a shot in the dark but was hoping someone got these. Thanks all
