If tapering works for you and people you know thats fine, I also advice tapering if its needed for the slight few who suffer from withdrawal of test and the symptoms they suffer from, in some it works with great effects. Ive always been a great researcher in this department with many protocols with shutdown and suppression and even had good blood work back from the good old dbol bridge.
But like anything in this game when we introduce chemicals into the body we all react differently, if you research about the HPTA and have a good understanding of how it works,shuts down and recovers you will know that coming OUT of a shutdown to try and recover using Test will only delay things, many things would come into play example age but ive seen studies showing that 100mg per week of test will still make your HPTA shutdown and not recover, I will try and find these studies for you to read but like many studies with every one there is a contradicting one which follows.
It impossible to say one way or the other except for people to try it and get blood work done to back up recovery but lets be serious here tapering was the fashion in the 80's so i am sure world wide experiences as set up the best pct procotol's to date otherwise it would still be the fashion. If it works use it but get Bloodwork to see if your really recovering or your just piggyback riding.
