Let me put it this way, when it comes to bodybuilding steroids do not make champions. Sure thing, they can puff up a body, but they do not create finesse. In saying this, I am not against people taking drugs, but remember, if you live by the sword, you die by the sword. There will always be a price to pay. For younger athletes, in my mind, there is no need to take testosterone because it is produced naturally. Focus on the fundamentals, perfect your rep form, boost your workout intensity, fine tune you nutrition, add some natural amino acids, BCAAs, EAAs. Hormone replacement does have its benefits for those over forty, for both men and women, But this should be left in the hands of a licenced practitioner, someone that specializes in anti aging and longevity. Just remember, longevity is the key. Muscle mass will fade with age, but you still want to be walking around at 80 without the use of the zimmer frame!
I will say, I preferred the physiques of the 80's and 90's before bodybuilding became distorted. It has lost a great deal of its finesse, although the new Classic Category may breath some life into the sport again.
