I have never pumped so have no idea.
Nasty side effects?? From FG you may lactate.
Seems some people are more sensetive than others with the effect of certain things entering their body. But this is NOT something you want, believe me! Gave me form I think????? but who wants to become a dairy cow. Just guessing to be honest, have no clue. But PM only as a initial test on what your body does seems alright.
Alright am a hypocrite am on so much more, but start slow. Read what your body is telling you and react but is slow, not instant, have patience
