Since I don't find it in searches I just want to throw this in about PhenTabz.
I've been taking them over the past couple of weeks. I do not take the recommended dose (2 pills a day) I take one per day with a cup of coffee for breakfast, every other day. On "off" days my calories are probably double what I eat on days that I take a pill. It knocks my appetite down and increases energy. It is just a form of speed, and not anything I would even admit to taking to anyone in real life, but wanted to share here just in case anyone wanted to know. Not recommended, and expensive, but it does work as advertised.
Side effects: Sky high libido (possibly more due to diet, but still sometimes very uncomfortable)
For me it has a slight laxative effect, nothing alarming but worth noting.
