Dries these stubborn lumps up like nobody's business! I bought mine on amazon.com a while back but never used it. It's pharmacy grade and was less than 5 bucks with shipping. I was curious and mixed mine with olive oil last night and applied to old lumps that never went down fully. They weren't sore or draining, I am just in search of a smoother groin and right armpit. Well when I awoke I almost cried at the shocking results. I know many of you are allergic to sulfur, and others not willing to try this, but maybe one brave soul will. I think there should be alot more of us living at least 80% pain free lump free lives by now, I encourage you all to continuously research and try new treatments until you find one that gives you relief.
