So your recommendation would be to suck it up and just wait until the cycle is done so the water retention goes away?
As your buddy pointed out, using Var to counteract the water weight is an extremely expensive way to go about it. I would say verify your E2 levels with blood work and watch your diet. Certain foods help retain water easier than others. The water retention will go away once the test metabolized out of your system and it'll only be a few pounds if you're good at E2 management.
