ur running a pretty ow dose. u should b shooting test e twice a week ex.mondays and thursdays. as for as much weight will u lose is all on ur diet and pct. if u keep ur diet up and do a mproper pct u will b able to keep most of ur gains other than the water weight.
usually time on-time off but the best way to know if ur ready to start another cycle is to get blood tests done and if ur blood levels are normal and stable then u can start another cycle.
prop is good in cuttibng cycles but it has to b shot everyday for optimal results.
