Too scared to try tris...I dont know..it just seems to me that the needle will hit the bone. lol
hoesntly, i used to think the same as you, i was always terrified of hitting a nerve too...
all i did was pick a spot directly under my bicep peak, let my arm drop and inject with arm hanging, altho i know guys who shoot with the arm in the air
i only tried as i was messing around after reading all the seo articles, wouldnt consider buying any if i couldnt stand the shots in the 1st place, still havent bought any but might one day
