Another thing to consider is this. I think a lot of newbies get pip more often because they’re muscles aren’t used to it. Yea veteran guys don’t get pip but they’re muscles are used to it. They think they found the “right source” but it’s just the fact that their muscles are just used to be injected into. I bet if these guys that say they don’t get pip injected into a virgin muscle that they never have before, I bet they’ll get some pip. Until that muscle get used to it. Pip is normal for newbs and muscle that hasn’t been injected into that much.
I have a blend I just made and when I inject it into muscles that I’ve had in the rotation for a while I get no pip. But I am also incorporating new sites in right now so I am getting some pip when I inject in those sites.
