The var will take a week or two to do anything. It isn't a magic fat burner. Assuming your supplies are limited, you would be better off doing 25mg var for 8 weeks IMO, though either way you're not really running enough to have any effect. You should see nice gains from the test though. This is also assuming your bodyfat is low enough anyway...

Weeks 1-8
Test prop 100mg/eod
Var 25mg/ed
