The first and foremost requirement before popping in any weight loss or muscle building pills as supplements, is to actually perform the necessary work outs to get the result from the additional intake of such supplements, in addition to your regular cardio and weight training work out sessions. None of the weight loss or muscle building supplements can single-handedly get you all the desired results of weight loss, muscle building, and a nutrient rich diet, as compared to the kind of results these supplements can provide, in addition to your regular and systematic work out sessions and a healthy, natural, balanced and nutrient-rich diet. There is not short-cut to this objective with the mere help of a supplement alone and no physical work out of junk diet etc.
The truth of the matter is that these supplements are not a substitute to the basic requirement of physical work outs and a healthy, nutritionally balanced diet. In fact, these supplements are effective only when used in addition to recommended physical work outs and a nutritionally balanced diet. The most suitable muscle building supplement can be best recommended by a professional trainer or physician, who is aware of your performance targets in terms of your weight-training work out sessions, to bring about the best results, from the supplements taken in accordance with the intensity and level of your work outs.
Different individuals are at different stages of body building and hence blindly purchasing a supplement, just because another person in the gym is purchasing the same, will not help you in any way whatsoever with your weight loss and body building targets. Depending on your stage of weight loss or body building, your personal trainer, will suggest the kind of weight loss or body building supplement, whose functions are most suitable at your current stage, and then you can select from one of the brands that sells, supplements to benefit the particular stage of weight loss or body building, at which you currently are.
