The advantage is specific to these compounds...
Anavar is a "Class I" anabolic steroide - and was designed to have a very strong separation of anabolic, and androgenic effect.
It's most effectively stacked with "Class II" compounds such as Dbol or Tbol.
Most people don't stack Anavar with Dbol - because they think of Anavar for cutting and Dbol for bulking - so it only makes sense to start the cycle with Dbol
and end with Anavar - plus both compounds aren't typically used for more than 6 weeks.
However, I am able to run them longer (and together) because I'm running the two at a lower level, so I'm not overdoing the oral compounds - which allows me to
take advantage of these two together for much longer periods... with minimal sides.
I originally got the idea of running them at low levels for longer periods, from reading of Arnold and Mentzer liking to run dbol at low levels
for very long periods.
Orals should also be taken on an empty stomach as food can decrease its bioavailability, caused by the fat-soluble nature of steroid hormones.
