I just came off two surgeries torn pec July and torn tricep November 7th. I am doing both TB500 at 2 mg twice a week for 6 weeks as JJ stated and the BPC 157 I take 250 mcg pull it to the 15th tick mark. I did this for two weeks I shot it where the doctor repaired my tricep tendon and my pec. Like Monday I will shoot in the tricep where he repaired it then Tuesday shoot it in my pec. After two weeks no pain, no swelling and my lifts in pt has gone up big time. I am way ahead of schedule for recovery time. Now I just am on a maintenance phase of TB 500 twice a month 2 mg and the BPC 157 twice a month at 250 mcg and as I stated feeling much better and recovery way ahead of schedule. If you can do both I would recommend both. JJ stated and he knows trust me he has helped me out with great advice.
