i am currently stacking a cycle of sustanon (500mg per wk.) and deca norma (400mg per wk.) I am taking 250mg of sust every three days ( which is about 500mg per wk.) the same goes for the deca norma 200mgs every 3 days ( about 400mg per wk.) i am wondering if the half lifes of these are long enough that i don't need to split up the injections. is what i am doing beneficial or is it just not needed.
