I've only done 5 weeks so I'm not a expert, I will say I did it and had no problems. What came to my mind then was what b.mo said about rate of absorption. So I went with it.

volume prolly has a factor as well... 1 cc here so not an issue. I did not even think about it until after I pinned.

I don't slam legs right after pumping 3ccs into my quads but for glutes I dont have to wait. I imagine increasing the blood flow by exercising the muscle would increase the rate of absorption and I think the injection sites have different rates as well. Glutes and delts are probably the quickest.

was kind of thinking and wondering the same here..pinned quads on leg day and seemed to be no issues. New to this so only my 2nd pin.
