For a guy near 40 that plays with hormones, HRT....legit HRT, is a good direction. When I say "legit" I don't necessarily mean going to the dr, but I do mean taking a real HRT dose and checking your labs to make sure you are in the normal range while you are not running gear. And then making sure that your cholesterol, liver, kidney and red blood is all in a good place, as well as PSA, before venturing on to the next cycle. For someone that in your situatuion, it's going to be be overall better, IMO, for your gains ,and for your well being, not to mention, probably better for your health than crashing out after each cycle.
As for fertility, this can be an issue for some, but there are a lot of men that are on HRT or even on cycle that make babies. I have seen it happen to a solid number of my clients, even while running some pretty serious stacks, including tren. HCG and Clomid will help with this
And thanks bro. I love what I do. I love helping teh community and I truly hope that my opiions and expereince have made a difference, especailly for some of the younger guys that are just coming up in the sport. I hope they can make better decision than some of those that have come before them. Some of the suggestions I make are based off mistakes I have made...things I wish I had done differently.
