Ephedrine is really powerful stuff.. It's a potent substance that I strongly recommend, but it is important to only use the legitimate stuff. It's almost impossible to be honest. I've sifted through many sites since Kaizen was made unavailable in the UK. I've found 30mg to be adequate for me and it works much better when utilized in conjunction with an ECA stack. But, I did have some luck recently! I'm not sure whether I could post any links on this site however, the products these guys sell has been similar to Kaizen I've witnessed. It's a powerful product for sure. I've shed a lot of weight and am currently at 10 percent body fat. So yeah, I like them. Anyway yeah here's the link Ephedrine for sale (Sorry for my English i'm from Iceland)
