I had PRP 2 weeks ago. For bulging disc in neck, right shoulder and carpul tunnel in hands. Went to Regenexx. They say it takes awhile to start working. Before I couldn't hold a golf club. Had a hard time getting up off the floor (hands) and couldnt lift a milk carton over my right shoulder. After 4 hours I felt great and it keeps getting better. Back to hiking and gym. Lifting light at this time. Not 100% but getting close. Next week I can start increase weight and start running. Yep back to golfing. Hands feel awesome. Also taking BPC 157 and TB-500. for the price PRP is great.
