I would say 6 years of consistent training is more then enough time to see what your natural ability to accrue muscle is and get a feel for your genetics etc...
That said -- 22 is young -- I still think you would be fine running ANY AndroSeries product at this point in the game. It will also be the least likely Androgenic product to impede your HPTA and mess with liver enzymes etc....
For PCT --- we have tested the testosterone recovery stack-2 and all testers recovered completely from the stack --- Serms can be harsh on liver, affect mood negatively, increase estrogen in the brain and are not ideal for ALL PCT requirements since different hormones have different mechanism of action and are test based, DHT based, 19nor based etc,,,,
I might only recommend nolva for aromatizing cycles as estrogen levels could linger in higher levels when going into pct.
