to DrAbs --
Following up on deadaim's comment, you are either A) running actives and not recovering, or B) recovering and into PCT.
Your body's testosterone production is mostly shut down once you are into a cycle. When this happens, you need to be taking enough AAS to compensate for the missing natural testosterone AND a substantial amount on top of that (otherwise, there is no point to the cycle). And when you are done with the cycle, you need to get your HPTA back in order as quickly as possible.
The gist of that is that it doesn't make sense to take a middling amount of a weak anabolic to finish off a cycle. You need to think "I am either ON or OFF." 300-375 mg of 11oxo strikes me as an undesirable middle ground, where you are hindering HPTA recovery but also not taking enough to get any kind of gains.
And as deadaim notes, that kind of middle ground also can complicate the estrogenic picture.
This will sound contradictory, but I will add that 11oxo is supposed to have a very short half-life. Patrick Arnold on another forum gave a SWAG of a half-life of a few hours. If you are smart about your dosing, and take it all at once in the morning (so that you are as far away as possible from the sleeping testosterone pulse), then 11oxo might help you to maintain gains as you enter PCT. Low-dose dianabol has been used that way for a long time. But you need to be doing full-blown PCT with a SERM for this to work.
