Here is my take on the subject and I speak with 20+ years of AAS use.

1)TREN dosing

300-400mg/week no need for more it is just wreck-less and stuipid only exception to go higher would be for contest prep
Tren e 2xwk
Tren a ed or eod

2)Tren e
Gives me more night sweats although if I add mast to the mix I find tren sides are less and that goes for both esters.

3)Cycle length
Tren e 8-10 weeks
Tren a 6-8 weeks

4) Tren for comp use
Only use Tren a last 8 weeks of prep along with winny plus some test and increase dose of tren as comp gets closer stop tren 2 weeks out and replace with halo or up the winny dose once tren is dropped and oral winny only.
Comp prep cycle use
week1-2
Tren a 100mg 3xwk mon wed fri

week 3
Tren a 50mg ed

week 4
Tren a 75mg ed

week 5-6
Tren a 100mg ed

Stop 2 weeks out and add halo or up winny dose last 2 weeks reason is that sometimes it is hard to fill out with tren in your system.

use the above rules and you will get all you want from tren.

Extra advise
Always control your E2
Have caber on hand
If want more lean gain keep Test between 250-350mg/wk
When gunning for all out mass test can start at 500mg/wk and move up to as high as 1500mg/wk at these doses you will no doubt be on an AI plus caber you have been warned.
