I never post anything but after reading these reviews I Took b5 and l carnitine, about 1-2 g of b5 and 500 mg of l carn for a little over a month. I read about the hair loss but thought, "oh it won't happen to me." Stopped when chunks of my already thin hair was falling out in the shower. 2 months later and no change. Do not take this, it is absolutely not worth it, any search on the Internet of ppl experiencing this will show you and guess what it may not stop and there is no cure. So yes while my skin cleared up a little and is less oily, this is no substitute for my hair. Please do not do this.
