Well you have several options, but as suggested by a previous posted get your lab work done and actaully see if your T levels are low. If they are not low then a standard cycle would apply with of course AI, HCG and proper PCT.
These two link will give you everything you need on cycles, SERM’s and PCT.
If you need TRT then you will always be using test every week for, well ever. It will pretty much make pct null and void until you make the descision to try and come off after a very long time, which is all together a whole other long topic.
Cycle length is again up to you. There is no set length as many believe. I would suggest 10 weeks being the very minimum for a test cyp cycle though but nothing wrong with an extended test cycle of 16-20 weeks.
Your usage will have to be scheduled according to your time frame and needs.
