For the clen, I would keep the dose lower. The purpose of clen is to create a greater calorie deficit, burning more cals, to get lean faster. So this can work in direct opposition to the cal surplus it takes to grow muscle. I would keep the dose lower and maintain a good clean, high cal diet. If she is running anavar for 8 wks total, maybe run the Var for the last 5, starting at 20mcg, then going to 40mcg, 2 wks later. Then finishing at 60mcg, 2 wks after that.
Just watch for side effects from the Var. Geneza is good stuff. I've seen a number of females do well on it. Just look out for mild sides like added body hair growth and facial hair growth, which will not reverse itself. Outside of that, the harsher sides that can go along with femles on AAS, will most likely not happen to her using Var
