SHe can go right into taking CLen - Clen is not a steroid, so it has no problem being run with Var (or right after it). Dose is same as men - the dose is individual dependent.
That said, Clen is SO VERY overrated. There are much better metabolic boosters. People only like Clen because it is illegal, therefore, they think it works better. Thermorexin is heads and tails ahead of Clen IMHO.
Also, a clean diet and good training will get you father than depending on substances. LIke TSO said, post up her stats and diet and training - I bet we can "fix" things so she sees results without depending on a supplement.
WHat were her goals with Var? What are her goals now?
