I've been on trt for several years now. Started on gels , went to compound cream, and for the last two and s half years I'm using test cyp sub q.... I've only ever used zinc and copper to control e2, haven't had a problem
Let's start by saying that many men using TRT in the physiological range don't need an AI as elevated E2 is "generally" not an issue.
Silverwing, you should know that most men who use a transdermal application of Testosterone don't need an AI as there is very little aromatase synthesis due to lower daily doses.
Men who use SQ injections rarely need an AI due to the injection methodology which is lower doses more frequently. Injecting SQ has many positives such as less painful injections and lower E2 synthesis.
For myself, when I went from 1 IM injection to two lower dose IM injections I didn't require an AI anymore.
However, I will say it again; there are NO natural or OTC aromatase inhibitors that have ever been proven to be effective in clinically managing elevated estrogen levels.
If they did work we'd all be on them and not on a prescribed aromatase inhibitor.
Find me one valid clinical study where a person with elevated estrogen levels had successful outcomes in lowering estrogen using any supplement or OTC product...I've never seen one!
Yes, there are nutritional supplements that have some anti aromatase inhibitor response but nothing near strong or powerful enough to work clinically in lowering elevated levels.
What I have seen over the years in moderating boards just like this one is that the men who did try to use them, instead of a prescribed AI, all failed at lowering their E2 serum levels.
If a man has elevated E2 levels due to their Testosterone use a low dose prescribed AI is the only effective way to suppress levels.
