Keep in mind that you'll have HPTA shut down and make very little endogenous testosterone, as a guy who requires TRT for low endogenous testosterone*, I can tell you the first 100mg alone is very noticeable. So at 350mg/wk you'd likely feel it if it were alone. With D-bol in there, you're definitely going to feel it, no question about it. * Of note, the reason I have low T at such a young age is because back in the early 2000s I ran SD, etc, a few times and my HPTA never recovered. I performed proper PCT. o_0
