The title mentions human arteries, which easily makes people think the subjects used BPC-157. In fact, this study placed leftover arterial tissue from surgery into an experimental apparatus to observe how the tissue contracts and relaxes. It provides evidence at a different level.<\/p>\n

\n

Coming from humans is not the same as being tested in humans<\/h2>\n

The study used leftover internal mammary artery tissue from 12 coronary artery bypass surgery patients, cut into small rings, and placed them into a tissue bath apparatus. The experiment dealt with removed tissue and did not give patients BPC-157.<\/p>\n

The advantage of this method is that it preserves part of the real vascular structure while allowing the experimental environment to be controlled; its limitation is that it lacks whole-body circulation, metabolism, and long-term use conditions.<\/p>\n<\/section>\n

First contract, then see whether it can relax<\/h2>\n

The authors first made the arterial rings contract, then added different concentrations of BPC-157 and recorded changes in tension. A decrease in contractile force under the same conditions can indicate that the tissue shows a relaxation response.[1]<\/a><\/p>\n

This is a tissue function experiment. It is not the same outcome as clinical blood pressure changes, rates of cardiac events, or patients' exercise capacity.<\/p>\n
