i've never done it (it will be my first cycle in a few weeks though)... but it isn't known for adding mass... that is why it is so popular with women... everyone i've talked to have loved the results they've gotten on it... supposed to give a lot of hardness and a little shape...
but then, like everything else, it will probably be dependent on the individual... a good thing about Anavar is that it has very little half life (lasting effects) unlike Primo or others that can stay in your body and continue to work for some time after the last dose... that means that if you aren't happy with the results you are getting on Anavar, you can discontinue the cycle and will have little or no ongoing effects... i read somewhere that its basically out of your system in about 72 hours
good luck..
