Can you please tell us exactly what type of muscle nutrition product it was, the name if this product and where it was purchased?
And/Or can you tell us what ingredients are in this product?
I take a creatine supplement for strength training. It has lots of other popular ingredients in it. I know where I get it from however and I am 100 % sure it's safe. Wall-mart sells it, has been for years and you can buy it online as well.
Exactly how do you know this product caused the problem? Exactly what did the doctor say? I'm asking because I am sure there are many good products from Brazil that can be ordered online - you cannot fault them all. But, there will always be good and bad companies that do not care about quality control.
We need more information please before we create unneeded alarm. Perhaps this one company has a history of problems. If this can be determined, then we could save a lot of people from freaking out and both stopping buying things from Brazil and stopping buying muscle supplements. Those two areas are very broad and i don't believe all companies involved can be at fault.
Was your son taking these products as part of a body building plan? Do the doctors have a treatment plan for your son, if so, how is it going? I do wish you and your son the best of health.
