I've always done this.
ANY muscle can be z-tracked, or to be correct, reverse z-tracked.
If you aren't shooting your quad, its hard as fuck to properly z-track an inject. So instead, the second you pull the needle out, pull your skin over to the side like you were preparing a z inject...
I have the same issue as you princess. I'm a guy and I have to hit 190 to get shakes. While the sides are nearly non existant, I still notice plenty of fat loss. Don't stress it if you don't get sides.
This was discussed a long time ago at avant but nothing really came of it. The only study I can find on the matter;
A member posted stating that two members of his gym who used DNP had there sides severely lowered by taking phenobarbital. Any information in regards to this?
I would filter the product into a multiuse vial designed for drawing and injecting. Doesn't seem sterile to uncap the hair dye bottle and draw out of there..
