There's no trouble getting Total T up, its that most of us have to inject EOD. If a low SHBG guy injected E3.5D, his trough would be rather low; i.e., 500s, and it would appear as though Total T is a problem, when it's not. Think of it as how fast T is metabolized, even if that's not totally accurate. Inject EOD and get tested in the 48hr trough and the guy should be fine in regards to Total T.
Low SHBG is not a problem at all, smaller, more frequent injections, if not daily injections, are how it's dealt with. When I was on E3.5D, I was up and down and up and down and up and down, its not a fun ride, as it were. But injecting more often gets the Total T up and keeps it there.

can you inject test cyp every day? Intra? my shgb is very low
