As with any AAS, suppression is going to happen, just to what level and extremes depends on the drug. So the proper thought process is to run PCT after any AAS cycle to maximize and keep gains and get your natural systems back up to full speed, ASAP, and you get another little kick from that also.
Anavar is one of the so called light drugs, no water bloat, fat retention, extreme size and strenth gains, that why most people dont think its worth it.
Var is expensive, buy if you buy it in bulk from a good source, the price really comes down. Plus, I would never run var unless I was 10% BF or less, thats where var really shines in putting lean, cut, vascular muscle on you.
I have run var over 6 times, for me the minimum dose I take is .25 X LBM.
Var also stacks very well with winstrol, eq, cee and primo.
