what what ive heard it was the other way, the oil based hits faster because they dont used the micronized time-release powder like they do in water (they have to use it in a water based preperation because it isnt water soluble)...
ive used water based suspension as the base of my cycle... definately the most i have ever 'felt' my test, regardless of running longer esters at higher doses...
you will have to spot inject, because you need to pin ED MINIMUM unless you are using it as a preworkout and have a base test... i had to run a little letro with it, and i dont have to run it very often...
