I went to the pharmacy today to try and get some B-5 cause I can't fing it anywhere. The parmacist told me that B-5 was Biotin. He gave me a bottle that comes 3000mcgs per pill. I told him that I was going to take a gram a day and he said that I would destroy my kidneys. He said to take only 6000mcgs a day for a month and then 3000mcgs after that. What is going on? Do you guys know what you are talking about or is he a dumbass? I told him it was to help w/ acne and he said that it can help for that. BamBam
