Found some very informative videos on youtube about regenerative peptides. These were doctors who practice regenerative healthcare (stem cells, plasma, peptides, etc). They say that in clinical practice, they have found very little difference in oral vs injectable BPC administration. They dose oral higher because it's not as bioavailable as injectable, but they typically prescribe oral form to avoid the frequent injections, and that it is stable in gastric juice. Of interest to me was that the body basically decides where to use the BPC for repair. They used the exact example I'm in, where one patient had a shoulder injury and gastric issues. In his case, the BCP treatment provided relief for his gastric issues first. After continuation of BPC, his shoulder then began improving. Very cool info. Also, they said if there is no improvement after 4 weeks, they move to a different treatment because that person is considered a non-responder. But most generally start to see results after about a week of use.
