Well I used ephedrine for quite a while but haven't for several years. I used GNC's legendary Ripped Fuel, but only one dose a day and only workout days. Yes, it works. However, even if Ripped Fuel were still available, I would be very cautious as I am much older and I'm not sure it is very safe for your cardiac system over the long term. There was once or twice where it hit me "wrong" and I felt pretty bad.
*ephedrine is still available if you really want it. I'm somewhat leery though of off-brands.
