I dont know why an athlete would want to use those... I think tendon strength and integrity would be all important to an athlete - which would make those bad choices.
deca, eq, primo... hgh combined with low dose test would make an athlete perform better and prevent injuries at the same time.
of course they would have to get around a drug test if they were tested.
You're not looking big picture.
These guys have strength and conditioning coaches, so regardless of whatever drugs they use, they can prevent conditioning injuries simply by following their protocols.
These guys have trainers who keep them loose and conditioned (if they choose to follow the advice).
As I said, if I were A-Rod and I was going to use it would be that cycle.....strictly performance related.
Using the weaker anabolics like T-bol/Primo/Anavar would be like kids play compared to a Sustanon/Tren/Winstrol cycle.
T-bol would be like candy on the side........nothing more.
I'm only speaking from experience.......but that cycle did more for me than any other.
Then again, I'm speaking from a strength perspective........and I laugh at people who do supersets using 60% of the weight I use.
The difference between a strength althlete and a bodybuilder.
