not really....each of the 4 esters end at different times. After 1 day one of them (prop?) is completely gone, and so forth. At the end you only have one ester still working so its like only 60-80/250. I don't have any old vials on me so I don't remember the exact numbers
To technically you are putting in 1000 a week, but there isn't 1000 a week in your body the whole time.
That doesn't seem well written, but do you get my point?
