Hey I've been waiting an answer from the derm. I told her about B5 she told me she could ask to some pharm to make me build the B5 pills with the powder inside. I didn't had any answer yet. Meanwhile I have not taken any pills. I just quit dramatically milk. No more milk. My skin now is pretty clear and no more zits. It's not oilish anymore, maybe because it's not hot and wet like this summer, because I don't drink milk and B5 help me. If I will next summer with the air conditionin system, suffer again from it I will buy and eat again for that perios megadoses of B5 vitamins. So by now i'm pretty happy with its results and haven't had any side effects.
