I used a fortified B-complex injection that is for animal use. I used a 25 gauge syringe that I bought from rite aid legally.
Trust me, I TASTED it (back of my tongue),and right after I did it I felt I could run a 400! BTW, my leg now is fine but doing some research I am curious as to the muscle tissue damage that occurs when you poke yourself. I don’t want to cause any undue muscle tissue damage.
