To be honest every pharm. company and drug research company or blind study is under suspission IMO.
I guess you can tell me what you are looking for or to achieve with Wellbutrin or other drug. Wellbutrin can and does have a stim effect (can ellivate BP) but not to a major extent unless your stim sensitive.
Let me know what your prob is and I will be happy to see if I can help and give you my experience and opinions
