well, if you're hoping to improve your cholesterol profile before you cycle, then that might take a while...
aside from fish oil and liver supps (TUDCA, milk thistle), i don't think there's a lot you can do to rapidly improve borderline cholesterol issues.
your liver values look good, so if you want to try the cycle, then you should be good.
however, if your doc wants to investigate putting you on TRT, then you are prolly better off doing that now, and you can add in the Halo later as a "blast"... Halo is a pretty solid compound, and i've never heard of anybody having estrogen issues while on it. however, you do need to watch your liver values.
