Hi
I'm about to start a cycle for the first time in nearly 5 years and as I'm older I'm really trying to be a bit more cautious this time round. iIm concerned about the stress that injectables place on the kidneys as they try to filter them from the blood. So.. my question is - As testosterone is already naturally in the human body, would injecting testosterone place less stress on the kidneys than another synthetic steroid like nandrolone??
Thanks
