Bro, other than being 19-Nors, Trenbolone and Nandrolone are different chemicals. I haven't done the research to know if they are even that much related but their origins and intended uses were quite different.

Trenbolone is kind of the "reference standard" in the whole notion of body recomposition that some contend is a myth. I believe in recomp because I have experienced it with Tren - I have never used Deca for that purpose. I'm an old school guy and the only time a run Deca is just part of a bulking stack. My response here is a super high level fly by - but if you want to reduce BF and increase lean mass seemingly at the same time - that is what Tren is legendary at doing.

It doesn't make any scientific sense to me, but Tren E "seems" like it produces less side effects (for me). My night sweats, panic attacks and the like eventually disappeared on Tren E although they probably would have gone away on Tren A but from what you're telling me maybe not. It's just a change in ester and half life - there may be some really sophisticated reason for this but I can't tell you what that would be.

I have always run Caber with either one - and have had ED on both which is a prolactin issue but no prolactin based gyno.

Can I ask a little about what you are thinking comparing Tren and Deca???

how many cycles have you done?

tren is tren man...ace or e its the same...the difference is the ester

people run ace for a first go with tren because it if you do see sides you can stop the tren and sides will subside shortly after stopping the tren. Tren E is a long ester tren so it stays in your system longer and if you see side from tren and you stop the tren you will still see sides for weeks after stopping.

tren is by far better for recomp...i personally get prolactin issue with deca nothing with tren
