How guys fractured n dislocated shoulder about 10 weeks ago.. Ive been in p.t for about 3 weeks now. I got my hands on sum tb500 did first sub q today kina burnt going in perhaps because i had it in fridge. I got the two mg bottle however only shot half a cc just to see how my body takes to it. Question is will this help me with p.t or will it just mask any pain and perhaps make matters worse. Also does it normally burn going in stomach feels kinda weird i used bac water to mix it
