I think the consensus is that aromasin/exem has less estrogen rebound effects, coming off adex has a bad rep for potential gyno problems.

begin taper down after you're off tam, exem should continue to encourage T production while keeping E under control. basically get your T production to where it needs to be, and then your E conversion. do a slow taper and pay attention to the low/high E sides and adjust.

After your cycle and pct is done, might want to look into prami to maybe reduce the gyno further. havent used it personally or know how it works for pubertal gyno, but some of the guys here seem to like it lol

hope this helps! GL
