Rating the Clenbuterals!

Hey, dudes -- I'm a fresh "Newbie" looking for info on clens. I've checked the educational threads and learned almost everything I need to know -- but I was wondering if anyone can tell me which are better than which (Novegam better than Spiropent or Oxyflux, German better than Mexican, ...etc.) Thanks!

Spiropent is by fat the best........if you can get them just stick with Spiropent if not i would say i think it is the chinese ones im not sure....the .04 the double stacked ones they pretty good....oxyflux is garbage.............and couldnt tell u about any of the other ones........
