Make sure it's pure Fenben without additives, this is very important.
On administration, take it with lots of fat.
AND, if you're going to topical route, use it with DMSO -- get the pure Ph. Eur. / pharma grade distilled stuff, not from the hardware store please. DMSO will go through anything, very powerful and will penetrate all cells (even cancer membranes).
