Injections

[lovbyts]

drape your arm across your bed while you kneel knees on the floor and inject in your shoulder

Why? Forget the shoulders. Most of the problems I read about are from people doing the shoulders or traps.

Using the quads is fine. Nothing negative. I use my quads 99% of the time.

3ml of test is a LOT especially if you are doing it in 1 shot. Why not split it up and inject at the same time as the tren? Also mixing it with the tren makes the tren not so harsh. Some people have reaction to the tren. Tren caugh or getting sore but adding the test in the same shot seems to make it more mild.

I use my whole quad from just below the Hip to a few inches above the knee using the outer, inner and top. I have been doing this for 2+ years 2x a week due to HRT.

I'm a quad injection fan as well. I find the closer to the knee you get the more painful it is. If you stick to the upper part of the quad, and a little to the out part of the quad, that's my personal spot of choice.
Good luck.
