Theoretically it is believe that winny even in lower dosages can suppress your Natural test levels, whereas it is believed that Anavar does not.. Something to consider.
For hardening hands down the Var...
The cutting aspect, I personally think winny does slightly a better job, but there are better options for this...and others may or may not agree with this statement.
For strength and no weight gain, a combo of them is miraculous...as would for cutting and hardening simultaneously.
What about throwing in some MC IGF-1 mixed with Var for cutting and hardening??
