I just learned that my brother who will be 17 in 2 months has been doing steroids since last tuesday (a total of 7 days). He did one deca injection last tuesday along with 3 pills a day. I was just wondering if this could potentially screw him up in the future (for example, his height development) if he continues. If he stops right now would there be cause for concern since he did it only for a very short period of time? Is there anything he needs to do besides stop to make sure he will not be negatively affected? Thanks for your help
