Finally! I've been battling moderate to serious cystic acne for almost 4 months. Damn Tren caused it. I've tried 3 seperate antibiotics, 4 topical treatments, tanning etc. Nothing worked. I was about to start accutane and I heard about Pantothenic Acid (b5). Either it was a coincidence that my acne was about to clear up or this stuff works wonder. 10 Grams a day for 3 days and my acne looks 5x better. Should be gone in 2 weeks or so.
