I have read that you have to inject hgh very slowly to subq. Is there any danger if you inject it to fast and can you ruin the HGH by doing that or your body potentially?
I mean if your injecting something into your body you shouldnt be in a rush, take your time if its causing discomfort from going fast you already know what you need to do!
It is going to the same place whether you inject slow or fast. Like Steve said, water based injectables will naturally go fast when compared to oil based injectables.
I think whoever told you that was trying to pull your leg. The speed of the injection will make no difference. The drug enters your bloodstream as soon as it's injected.
