BPC-157 after Stem Cell Treatment

Jay, I recently had PRP and BMAC on both of my hips for mild to moderate arthritis and left/right tears in my labrum. I def see progress after three weeks. I just started bpc-157 last night with .1ml or 10 units. Is prescribed once a day at night but I see guys doing it twice a day. For the first injection, I put it in my belly. My question is should I put it more down in the groin area where my labrum is or top of the hip muscles for better results? I was a little nervous for the first time I didn’t want to hit any blood vessels. Will I get the same effect if I just put it in my belly? Also is once a day enough bpc to heal or should I take it more than once a day? Thank you! Joe
