Q: I took once supplements for 5 months and gained 5.5 pounds of fat and lost 1.5 pounds of muscle.I was doing lower body weight training at the time. I gained fat because I took too much supplements but I cant understand how I lost muscle.I will never take supplements again.

A: Results like that are almost guaranteed to be due to a sub-par diet during those 5 months, not due to supplements or weight training. You should also keep in mind that body fat measures are very prone to error and relatively small changes (like 1.5 pounds of muscle lost) can be entirely due to measurement errors as opposed to the actual muscle loss. Finally, many supplements are meant to be used for weight gain (hopefully muscle gain), so without knowing what supps you took, I can't really comment on what went wrong. But in general, yes, supplements, at least the legal ones, are far from being the magic pill that some people expect them to be. 90% of your success will be determined by your diet and execise programs and how closely you stick to them. And large unwanted gains in fat are almost always due to eating too much or eating wrong foods.
