the general consensus is if you dont know how to run short and long esters together then you aint ready to do so. The vast majority of members here are noobs so the vast majority of advice is directed toward them and keeping them safe. can they be ran together ofcourse, I do it all the time.

I run both long and short all the time. I always kick with Prop evry cycle. But I like starting new brands or compounds with short esters. So this cycle I'm on, I went with tren ace to be able to adjust my dosages if I wasn't able to handle the sides. I'm also on test prop(Kicker) and test e. I already know what Test E will do with my body so I didn't need to worry. Tren is normally going to give you different sides depending on who brewed it and the solvents and dosage. Last time I ran tren I tried a new brand and went with tren E. The stuff was fire but I had some wicked sides and before I knew it I was going crazy!! By the time i got off the tren I had gotten in some major legal trouble.
As far as pinning schedule bro you can pin more than 3ml on ur pin days. After you pin 3ml just pick another site and pin again. And yes you can pin the long esters more often. I pin the Test E on M-W-F. You should see 7Gothics pin schedule and routine!

IMO, Its not that easy due to the overlapping half lives and the building effect. According to the attached link to a post the mg injected to ng/dl blood levels are not linear so it makes it difficult to guesstimate. You could spreadsheet it out and get close. The values listed only go down to weekly shots. http://www.eroids.com/forum/general/over-40-trt/my-trt-chart-test-eth-do....
Edit: Thinking about it after writing that it probably is easy. I go e3d instead of the 2/wk for simplicity and an extra shot or 2 I could just lower the amt a nudge and go eod.

Im running short esters with long. I'm currently running Test prop/NPP ed/eod along with test cyp and EQ weekly. It's not uncommon. At least I don't think it is

Trying to kickstart Deca and Tren, the only problem I've had with it is when they both overlap, and you say to yourself should I really be pinning 6ml or should I push back my eod a day, then you realize if you push it back a day its just gonna come up again in 3 days so you do it. Then you start thinking, I just pushed close to a gram and its an off day. Should I move my workout up a day to take advantage of the gram. Then you think but that will through off tommorrows schedule and thats really when everything should be spiked and you go around and around in your head til you just decide fuck it, from now on i'm just gonna pin short and long esters ed and not thave to worry about overlapping schedules. Not that I would do that but I know this guy and...... jk LOL ;-P I think its just for simplicity.
