Nope, you're good to go. I've swallowed as many as 16 in one dosing time. Mix in something like Gaspari's Plasmajet at 10 caps/dose pre-w/o and things can get kinda crazy!
Just make sure to drink plenty of water. There's nothing worse than getting something "stuck" halfway down, opening up, and you burping powder. That can be pretty nasty!!
