Do all PH's shut you down

[aaronsoccer4]

My question is, do all PH's shut you down, I'm 21 years old and do not want to stop my natural testosterone production because my growth plates are still open, I'm looking into PH's and want one that will not do this, if they exist??

Yup for the most part they all effect you.
