3 major components needed for maximum muscle growth -
In no particular order -
1 - resistance training ie heavy weights 45mins-1hr
2 - excess cals from protien,cards and fats - roughly 500cals-1000cals a day more when on gear
3 - REST - We do not grow in the gym! We grow when we are resting,get as much rest and sleep as possible to reep the benefits while on gear.
True steroids can make you have more intense workouts and possibly speed up recovery times BUT unless you are built like a pro on 3g of gear a day norm routines apply.
3-4 days training routines are plenty for the average trainer using gear and allows ample time for rest and growth.
Thats how i have done it anyhow
Just my 2 cents
