Ephedrine can be extremely powerful. It is a powerful drug which I would highly recommend, but it's important to only use the legitimate product. This is almost impossible to be honest. I've sifted through many sites over the years since Kaizen was made unavailable in the UK. I find 30mg to be adequate for me and it's more effective coupled with an ECA stack. But I've had some luck in the past! I'm not sure if I can post links here however the product these guys sell has been nearly as close to Kaizen that I have seen. It's very powerful, I'm sure of it. I have lost a lot of weight and am currently at 10% body fat. So yeah, I like them. Anyway yeah here's the link Buy Ephedrine UK (Sorry for my English i'm from Iceland)
