Less people complain about deca sides when they taper their dosage like the bbers back in the day used to due. This basically shows that the sides experiences is a buildup of the deca ester in one's sytem-so i agree with your original idea. One suggestion though. Change out the Tren for either Var or Winny, and that s for a fe wreasons. One, your body will already have one nandrolone derivitave (deca) so adding another one (tren) opens yourself up to a slew of progesterone sides-you DEFINATELY dont want those. 2, its always a good idea to finish up a cycle with an anabolic compound, not something highly androgenic like tren dbol, exc exc. This will help solidify gains and eliminate water, giving you that ripped, hard look.
Either way, whether you ignore my advice or take it, run .5mg Cabaser (dostinex) e3d to help prevent progesterone sides.
