Yeah, I know guys hit sites for the "pump" effect, never really felt it myself. As soon as you inject, the liquid is being dispersed throughout the body, it doesn't just stay where it was injected (some think this is true). The body's mechanism for natural balance works to keeps comparable body parts from becoming overly unbalanced. However, most folks I know put shorter esters in the bis/calves/etc because of the quicker shot frequency so it isn't a week or more between. For me, "long" tests are glute and thigh.
