Generic Plavix is used for reducing the risk of stroke or heart attack in patients who have already had a heart attack or stroke or have other circulatory problems due to narrowing and hardening of the arteries. More info »
Regarding the effect: I do notice an increase in bloodflow and a better
stamina using the pills (I use 50mg). A side-effect I have noticed is that
my nose clogs up so I seem like I have a cold for an hour or so after taking
one pill. No other side-effects than that.
