I found Life Extension Benfotiamine on sale, I usually use Dr's Best. I am wondering if anyone has every used this company/product, good, or bad???

Also, I have never bought or used biofreeze. Everytime I think about ordering it, I read reviews and they talk about it being cold then turning hot. Is this true??? I know MrsD said she uses it but I am definately not wanting to try it if it even remotely gets warm, I want something that is cold only. Anyone???? Thinking about ordering the spray gel.
