You should not have estrogen/estradiol issues on a proper TRT protocol. Period. If your levels are elevated then it can most likely be attributed to 1 of 2 things. Either your test dose is too high or you are not pinning frequently enough. You only want to be at the higher end of the normal range but not above it. As for frequency, run a long ester and pin every day if possible. The minimum I would advise is twice per week but it will make a big difference if you can do more. Esters do not work exactly how they are on paper. In real life, our bodies want to produce testosterone every single day. When we mega dose once per week, the body does not treat that the same way (even though there are esters to cleave off) as it does when just receiving a small dose at a time.
