| Hmmm, there are 3 first time posters on this thread, maybe a sales pitch is coming.
First off, Ephedrine has tight controls on it's use for a reason, for a start it's addictive, the last thing you need is an addiction to a drug that you won't even be able to obtain legally for much longer (not that any kind of addiction is good)
Secondly, Ephedrine is a strong stimulant, if you stack it with caffine you risk having a heart attack. Working out while taking this will only increase those risks |
