Testanón
Hi: I live and work in Mexico and use this product. I have lote #19 and can tell you that it is much less painful and more effective than the redijects from Ogananon I used before.
I have heard that other lot #s did have a problem with high alchohol content. You can search the board for the #s.
I have had no problems whatsoever with their gear.
Good Luck!
