I think the caffeine was implemented because of a Portuguese study that said anavar was a lot more potent when mixed with 300gr of caffeineOnly if you believe it to be true it's interesting. Creatine and var isn't exactly New, they both can make your muscles fuller and people do use them sometimes together for contest prep because of that, take more creatine and you have spurfys idea. The coffee literally does nothing in terms of fullness or muscle building. Try take anadrol with or without creatine and you have the same effect, same with superdrol, only difference being they are cheaper and far more powerful but also more toxic.
If you take winstrol you have the opposite effect, it dries you out. All this will eventually leave your body making you flat compared to when you were on the cycle but thats with any aas really.
