couple different ways to go about it...
one, is longer acting drugs used for 16+ weeks before taking a "break"... both mentally and physically, easy to get burned out and loose sight of the goal. think 4g enan plus 2g deca.
the second is to use the same test 'base' (enan is my fav for multiple reasons), and cycle in and out a few different drugs for 20 weeks. switch out injectables every 4-5 weeks (NPP, TREN, MAST, EQ, ect...), and switch out orals every 2-3 weeks (drol, dbol, tbol, ect...).
they both have their place... if it's offseason, i'll go with a combination sorta... and go 20 weeks
4 grams of enanthate aka 16 cc's at 250mg's a pop. I just don't see the point in going beyond 750-1000mg's per week. Just my opinion.
