I like to frontload sust personally. I've done it twice now and really liked the immediate kick I got. I frontloaded 300mg/day for two weeks, then cut back to 1200mg/wk. The longer chain esters from each injection take anywhere from 5-7 days to release to peak levels, and then linger around down to a taper-off up to two weeks later. The fast-acting esters are in fairly low levels in sust and release within 1-2 days. So, daily injections will keep the fast esters present every day, while the longer ones are releasing in progressively higher amounts with the addition of daily shots. Around the 8-10th day, the combination of immediate action from the shorties and the full kick-in of the slow release guys is really killer. I didn't try frontloading 2weeks before my planned cycle, but sounds like it would be nice to try as well.
