I would definitely work quads the day of injection. I take 400mg/Ml Test E and 400mg/Ml Deca in one shot...Pretty concentrated gear. It has quite the kick 24 hours after I pin if I DON'T work the muscle that day. But, when I do an intense leg workout the same day as I pin, the PIP and leg workout soreness just kind of merge together and is definitely less severe.

I honestly like working the muscle I just pinned...be it my quads/glutes, lats, delts, etc. I think it works the oil around instead of it justing sitting there. You might have some crazy ghost-pip the day after, but then it goes away super quick too.

The more the oil sits in the muscle without being spread around, the greater chance for it to build into an infection of some sort. This really can happen...I don't remember exactly who it was here on Eroids, but they pulled some nasty shit outta their delts and posted the pics. They talked about how their shoulder had pip for an extended period of time and was really hard and warm to the touch and all...telltale signs of an infection building. Syringe was full of pus-lookin puke...BLARF!!!

I suppose it depends on if you have really bad PIP, but otherwise haven't had an issue and have still had nice leg workouts after pinning quads.

I pin and hit it hour later. If not leg day its bike/treadmill. Get the oil dispersed thruout length of muscle for faster oil absortpion and less of the steroid stuck in one spot which causes soreness. Bad mistake is pinning before bed. Oil sits in that one spot irritating fibers and wake up with pirate parts.

It doesn't make a difference, if you have PIP and it is to painful is when people don't do it, but if no PIP than just stretch before you workout and get that good leg workout in
