Long esters are felt in my system a day or two after and then become more pronounced.
When I pin short esters of test and tren, I wake up the next day visibly more shredded. Some people have pointed to certain studies and talk about half-lives and this and that, but I can take pictures and feel it physically. I'm going to go with what I know over conjecture any day.
FWIW, with long esters I'll put them usually every other day or every two days. But when I start them, I'll pin ED for a couple days, day off, ED, and then switch to EOD or a few times a week. You want front-loading and faster results? There you go... just pin a couple extra times at the start and you're golden. No need to complicate anything.
