yeah ace is faster but remember that it comes in oral form and won't survive in the body that long like injectable E so u'll have to take more mg's , for ex: 400mg primo E /week is the equivalent of 100mg Ace /ed , so it'll be more expensive.
There are several sources that sell Primo Ace injectables. One of the other benefits would be that you get more actual Primo mg for mg with the acetate esther.
hehe , i know how u feel , i like it too specially with short esters like ace and prop , i shoot them in the evening and i feel the peak early in the morning and i start my day with a good mood.
