It really depends on the individual, and you will recover in time in most cases without post cycle aids, but it will take much much longer, and you will lose a lot of what you worked for.
I caveat that by saying you will recover naturally from a shorter cycle, and not many of them. The longer the cycle, the higher the risks, the more cycles, the higher the risk. Run a year long PH/AAS cycle and you are probably going to have issues for a long time, if not forever
How long/how many cycles..isnt a number someone can really determine. It is based on each individual. Some could run test a year and be fine, others could run one 12 week cycle and have issues forever.
YJ is correct, it is reprehensible how most of these supp companies will pump out the PHs and not even touch on recovery.
It is also why I support banning PHs in a lot of ways. Too many people are doing them, and have NO idea what they are doing to themselves.
