So imo it's no way worth it.  Finish off your cycle currently like just do it k dawg 

 take 6 wks off.  We all know it sux !!! 

.  But It's is basically a weeker Anavar in comparison.  My girl will never use osta again.  She says nothing is better then real Var and I agree 100%  This is why mini stacking or whatever that is you are saying is no bueno.   Take the time. Then yes Always run some test with ANY anabolics it's must b law.  How many times us vets say that shit lol. So bro I promise next cycle run 40mgs of var a day for wks 1 to 3 bump to 60 the last 5 WITH 250mgs test min a wk.  Your gonna kill it and never think of osta again.  Good luck my brotha
