I think the thing to look at is not which substance will shut you down the hardest but which substance will shut you down the longest from concluding use.
This is an ester based thought. Deca will shut you down because it has a long half-life. NPP, the same drug. has a short half-life.
SO if you are serious about doing the most to not hurt your HPTA...dont do roods.
If you are logical and accept the responsibility, pin more with a shorter ester, spend for HcG, and recover via PCT faster
Which substance is detectable longer is a different story.
