I would strongly recommend reading through all of these threads here in this forum and see all of the issues people are facing.
HRT on its own is an extremely complicated process (more art then science) if you decide to add additional uncontrollable variables to the mix (i.e. - a cycle) then you are increasing the risks significantly.
but that is just my own non-medical-porfessional opinion (plus from someone who has never done a cycle) so listen or ignore at your own prerogative.
and I think that this website has a forum dedicated to cycles specifically. Not sure how many people here in the HRT forum have the experience you are looking for. most just want to get to feeling better or normal.
HRT on its own (if it is working correctly) should help you gain muscle, loss weight, and improve your health overall, but not as fast or as drastic as a cycle.
