sounds like you need to do some research bro. Just to help you out a little, PCT stands for Post Cycle Therapy. PCT is used after a cycle of many AAS and PH's to kickstart your natural test production and to surpress estrogen levels in your body. The reason being, that since your test levels are elevated during many AAS and PH cycles, your body lowers its level of production because it does not thing it has to make as much. I could be a little off on the exact science but thats the general idea.
Some of the sides you can possibly face when doing PH's or AAS are the following:
aceleration of male pattern baldness
benign prostate hypertrophy
acne
aggression
gyno
bloating
severe back cramping
testicular atrophy
high bp, causing headaches
liver toxic
as far as taking it, someone else will help you out. I don't do ph or aas but i hope i helped you out a little with what PCT and some sides could be.
in the end the choice is up to you. good luck bro. research and make an informed decision.
