No food supplement can make initially incorrect workout efficient. That’s why the majority of highly advertised food supplements are simply useless. If your combination of training, natural food and rest is unsuccessful don’t believe that any food supplement can improve it. Most probably, the problem is that you either train, or eat or rest improperly. Find the reason of your failure and get rid of it; only then you’ll be able to ‘grow’ and only then it will be reasonable to experiment with food supplements.
A lot of beginners firmly believe that their muscles start growing as soon as they start taking one or another food supplement. When they don’t see any growth they direct all their enthusiasm not to organization of correct trainings and nutrition but to experiments with another ‘miracle’. They simply don’t understand that any food supplement is useless without considered training, balanced nutrition and full-fledged rest.
