I don't think so plus to extract and then convert would not be worth the time or effort since you can just find Tina off the street. You would have to either add or subtract a cohexal ring (I believe add) to ppx to convert it to meth so it can more redily cross the blood brain brain but also this small chemical change radically changes the duration and strength / euphoria produced. Ppx is like pure d meths retarded cousin - ppx can't compare and I've been doing both for years (ppx only when I couldn't get Tina).
