Weren't you running some sort of AI while crusing?
Why bump the test if he is having aromatization issues at 200mg? That doesn't make any sense...
Honestly, I would just start 40mg of Nolva ED until the lumps are gone along with Aromasin at 25mg ED. Once the lumps are gone, cut the Nolva to 20mg for a week, then 10mg for another week. Keep your Aromasin at 25mg ED on your cruise, unless your E2 levels get too low. If they do, then cut your Aromasin to 12.5mg ED...
If you already have letro, you can taper up to 2.5mg like the poster above mentioned and keep it there until the lumps are gone. Then taper back down, but run the aromasin the same way as I outlined above. The aromasin is key to preventing estro-rebound.
You should PCT once this has been resolved, as you are too young to be blasting and cruising in my book. You have a long life ahead of you, and I would hate to see you on TRT for the rest of it.
