500/week!?! Have you done that much? That's a truckload. 300mg/week should be fine and expect 3-4 weeks before it starts to build up a more stable blood level. I know a guy who felt it at the end of his first week. Remember, with oil-based injectables, it's not as if a week goes by and then it dumps into your blood stream. With a long-esterified injectable in oil, it will take a while to be released into your blood, starting the day you inject, and slowly build up and slowly taper off. That's why smaller injections, say twice a week are good. You always have stable blood levels. If you're two weeks in, you should be feeling at least something.
