You cannot use an Oral steroid longer than 8 weeks non stop , thats why you cannot run Oxandrolone along side with Test. You gonna use 5 weeks in the end of cycle.
Dont be greedy

its only start.
Second this is a very moderate dosage, normally you cannot have gyno from this, but like i said Nolva + Proviron or Small dose Arimidex or Aromasin is enough protection.
I am old school, i only use Aromatase inhibitor (AI) when its needed for sure but i told you its your decision, read more and decide by yourself.
