I have been taking oral BPC 157 for about four months, and I can truly say it is helped a lot of my gut issues! I hurt my knee somehow using a knee sleeve that I guess put some kind of pressure on the nerve under the kneecap and the bursa sack so I started injectable also 500 MCG and I believe I’ve had four or five injections daily just once a day except for one day Wednesday of this week I did miss an entire day. The injection site leaves bruises each time. Any idea why? I am on Triz 5mg which I give in the upper thigh area no bruising versus the BPC 157 I was injecting as close to my knee as possible so it’s along the side of my thigh close to my knee joint. I have not noticed any improvement sadly but I would imagine it takes quite some time.
