In the years immediately before and after I turned 40 I was training the hardest I had ever trained in my life with some guys who "considered themselves"
to be cutting edge researchers in TRT. (they had access to the cream and patches not injections).
anyway, in my very small scale experience I observed that
1. It doesn't make everybody Randy Couture.
2. It probably contributed to more training injuries. Because you might feel recovered and ready to go but you're still 40 years old.
Just between you and me, I could use some of that Sh** now. I hope Hendo markets his own brand.
