I was able to get thru a full chest workout yesterday with minimal pain, so that was great. However later last night I had quite a bit of pain come back in my shoulder. Unfortunately this, along with the knee swelling after my last hike, is making me feel like maybe TB500 is better at pain management than it is at healing. I'm 12 days in at this point on the TB and just back in the gym after a week off, so I will reserve judgement until I've made it thru this training week and seeing how I feel. But if I'm feeling good before a workout and falling apart after, TB isn't giving me the healing effects that I was going for, and will switch back to using BPC. In fairness I am 51 and well beat up at this point, it's possible that both TB and BPC won't be miracle workers for me at this age. But I'm on the fence now and ready to switch back BPC again if this week I don't show signs of getting past my injuries.
