Anavar is a known dry steroid we are not talking deca.
You are over complicating it.
If you eat the same with the same aas and add 20-30 mg of anavar for 4 weeks you will do more pull-ups then without the var.
Most AAS increase glycogen retention regardless of whether they’re aromatisable, or “wet”. That’s one of the reasons why AAS change the look of your muscle and make you look “full”. 1 gram of glycogen is bound to 3 grams of water when stored in muscle.
Then there’s nitrogen retention. Here’s a study which looks at the nitrogen retention of anavar.

Nitrogen retention is literally the measure by which compounds are considered anabolic or not. Every gram of nitrogen retained makes you 1g heavier.
