The reason people would rather take tren ace is because its a shorter ester, so if one doesnt know how their body will react to tren , they will take tren ace so they can jump off it asap instead of waiting 2 weeks to get it all out of their system. Tren has really bad sides for some people and one wont know how your body will react to it until you take it. I like Tren A cause I use it when Im doing a lean part of my cycling so I dont want to run a 10-12 week. 7-8 weeks gets the job done so the shorter ester is my preference.
The pinning sucks, but since I run it with Prop, Im pinning frequently anyways.
In theory, Tren Ace should have fewer side effects , thanks to more stable blood levels from the more frequent injections with smaller shots.
However, after reading the experiences of a lot of people, it seems that in practice, people experience less sides with Tren E. Apart from the sides, the biggest difference would be the duration of the cycle .Tren E is the same as any other long estered compound in that it needs time before it starts to take effect. It should be run for at least 10 weeks just like Test E. Ace is pretty close to prop and is more suitable for a cycle in the 4-8 week range. If you want to lean out i think prop and tren a is going to be a killer combo. i am getting ready to run this cycle myself (just got to get a lot of work out of the way.) i think in the end its kinda like test tren is tren just long or short depends on your goals and the other compounds you're running.
