I have been cycling with cyp, deca, anavar for awhile now: 200 / 250 mg per wk. At first I ran a 10 week cycle, but I have extended them to 14 weeks or so. I notice that plateau too quickly now, so I think I need to mix it up. I know guys that have gained big on Tren and dbol, so I'm thinking of adding that to the mix.
It's hard to go wrong with test and deca. You're plateauing because your body has maxed out with those (light) dosages. Drop the Var, and try Test Prop 525/ NPP 525 for 10 to 12 weeks.
