So if your test levels were "shot" before you ever touched a steroid, you did a 6 month tren cycle with no hcg, fertility is not a concern... I am completely missing why you are doing pct? Do you just like to suffer? Your test levels will be worse than they were before you did a cycle 3 times longer than recommended lengths at the age of 38. No protocol is going to turn back the clock for you. If keeping your gains is a concern go on trt. That's what it is for- older men with shit test levels.
