At 250 mg a week your body would be producing around a High natural level so in theory yes your body is getting a break from your blast which are going to be higher. Just because you blast and cruise doesn't mean you can't have kids.. Know plenty of people that have kids doing this. Your body is an amazing thing it will bAlance out even after blasting Nd cruising.. Yeah your test levels might be on the lower side..not always but it's always possible and I'm not saying it isn't possible that you will go sterile.. Anyways blast and cruising is for someone who is either older and ready for trt Orr someone who is very serious and wants to compete.
