honestly, its just a really poor questions because there's different scenarios, goals, etc... both of these have some of the highest amounts of side effects you will come across... tren gains will be FAR cleaner and more sustainable and although the sides of tren are horrible, deca is worse... i would honestly not use deca if you paid me but that's just me... these questions are just very poor because no scenarios are given, no past cycle history, whether you are prone to certain sides etc... there's a million factors... they are not similar enough to compare without more facts...
