FitnessFrk said:true test levels "peak" in the 20's but levels begin to raise sharply in the teen years. along with many other hormones.
the teen years would be the worst period of time where a person would want to "experiment" with things with no substantial positive medical evidence let alone what negative effects it could have on someone during the main growth years. "growth spurts" occur in the teen years.
I appreciate your concern, but I still don't know what beyond premature epiphyseal closure makes steroid use in teenage years any less toxic than in adult years. I know you have alot of suspicions, but as a scientist I want facts. Personally, I can't point my finger on any.
