I wouldn't recommend Clomid as its only purpose is in-line with those who aren't on TRT. On the other hand, nolva is good to cycle for a little while on TRT or after blasts because it's known to help improve lipids.
Other than that, if you're planning on staying on TRT then SERM usage won't be too much of use to you- especially Clomid. Although, Nolva is nice to have on-hand though as it's very effective at putting an end to an early onset of gyno while you dial in your AI and for the above mentioned reason too (dealing with lipids).
Might I mention, if lipids or bloodwork are of any concern to you then take a look at Cardarine. It helps fatty acid oxidation and will improve your lipid profile as well.
