AAS make your muscles grow stronger NOT your tendons! That is one of reasons why everyone is telling the younger to get a solid foundation first, it is not uncommon to get sore tendons as they grow stronger. It is also not impossible using AAS that your muscles become stronger than you tendons causing injuries including torn tendons. If you think that a hard day of work hurts your arms, wait til you tear a tendon and be down for months!!! Just my .02 but be careful bud.
