I would recommend against crushing the caffeine tabs. Last summer, 1fast hadn't started carrying the bulk caffeine anhydrous and I couldn't find any caffeine capsules. So, I bought the Prolab caffeine tabs and a pill crusher from the pharmacy. The crushed caffeine tabs contributed to quickly clogged the pump dispenser. Also, it's gritty like putting on sunscreen lotion without showering after playing beach volleyball. For added fun, throw in a little overexposure to sun and then rub that gritty lipoderm (the alcohol in the transdermal is nice on sunburns too).
