i play rugby alot and am also a royal marine. i have to have a good level of CV fitness for my job and sport but i wish to get more power in my rugby tackles and overall game. I have been training hard to improve this but want to start taking protein to increase muscle power but not size as i am happy with my build.I have heard that Creatine can affect your running performance and naturakky i stay clear of it. However, someone recommended me to take Cyclone because of its properties but i know it contains Creatine so am worried.So, can you tell me whether taking Cyclone wil affect my running and if i should go with Promax?bearing in mind, i dont wish to increase in size, just become leaner and more powerful?

Thanks
