Guys, please.
TRT is intended for the treatment of hypogondism - low to no endogenous testosterone production. Therefore one uses exogenous testosterone in the form of testosterone injections or creams. Eventually this causes your body to no longer produce the very little endogenous testosterone your body did before the beginning of treatment. Therefore it is considered a lifelong treatment if one decides to go that route.
The use of other androgens will not require a post cycle therapy as you no longer need to restimulate your HPTA becasue your endogenous testosterone prodcution is no longer viable and has been replaced with exogenouse testosterone in the form of TRT.
OP - No, you do not need a post cycle therapy after using other androgens when on TRT.
