I have been reading more and more about how the impurities of generic (blue top in my case) GH can cause the bodies to produce antibodies and fight its natural GH eventually....maybe i am not understanding this correctly.

either way, what are the chances of this occuring? has it been proven to occur? is this something that should make me toss the blues i have (just kidding )?

im currently running 10iu PWO (3 times /week) and 4iu on non workout days.

thoughts?

thanks,
