yea, it can raise your blood pressure. Also can make you hold some water...but you would have to take in quite a bit to really start to get side effects from it unless your prone to them.
I can eat a couple of slices of salami or pepperoni and the next day i am PUFF THE BLOATED DRAGON. I really like the effect it has on my lower pecs, it really fills out my pointly ass nipples and makes me look like a tub of lard, which i am not.
water retention and i aslo read an article stating that it was bad for your sperm production or testicles or something to do with that nature, but just worry about the water retention
