As far as local growth I know it's not supposed to cause any but my quads experience says otherwise.
I just hit quads for the first time a few months ago and...it could have been my mind playin tricks on me but I noticed this too.
love hittin quads now
but If the oil is being stubborn and not going in easy the needle starts bouncing a little and I end up sore.
This is my first cycle and haven't pinned anything but quads. Will start a better rotation next cycle when I'm pinning more than twice a week. But since I started using gear with coconut oil I get zero pip.
i'd rather use the quad than any other place.
then again, i remember getting full spasms down the leg a few times....had to pull out and re-inject....
but that was quite awhile ago.
