Your body doesn't digest food at one time. It continuously digests proteins and turns the protein into amino acids and then it shuttles the amino's where they are needed. Sometimes your muscles don't always get that 40-50 grams because of stress, being sick, infection (healing). Amino's are what our bodies need to grow and to repair so you answer is eating protein/meals every 2 hours is the best way to grow. Constantly feeding the furnace to make sure there is enough there. Working a muscle twice in the same week is fine. But rule of thumb is train when your not sore or give that muscle group 72 hours and if your eating and resting enough you should not be sore unless you tore something. I prefer anavar it is not as side effect related although they are similiar they have different capabilities when taken at the right dosages. Winstrol can some times cause a joint pain while anavar does not. Winstrol can dry the joints a tad more and that is why I favor anavar. Site injections ar okay if done with the right gear. Deca is a good site hitter and even test propionate 100mg in the delts can cause a good visual.
