Lowering it would probobly lower LDL (do you know if it was lower before TRT?)..
However. your total test is within physiological range, and if you feel great, and now have the motivation to take care of yourself I think lowering TRT just for improved lipids would do more harm than good.
You could simply get on a maintenance med to bring your lipids into a range that stops additional plaque accumulation. Pitavastatin and Ezetimibe are side effect free for the vast majority, and will bring LDL into a very healthy below 1.4 range.
ESC/EAS (European Society of Cardiology / European Atherosclerosis Society) guidelines, the most up to date in the world, call for below 1.4 for high risk patients (even below 1.0 if it can be achieved). Although not explicitly addressed in the guidelines, AAS use qualifies as "high risk".
And bear in mind, the only reason they "risk stratify" lower LDLs, the higher the risk the lower the target, is economic. Everyone would benefit from the lowest target, but the lower you go, the more expensive
it becomes. so it's reserved for "those who would most benefit".
