Weāve already covered GLP-1s (and yesāthereās a deeper dive waiting for you in the classroom š). Feel free to cruise the GLP1 E-Book Todayās cameo appearance goes to BPC-157, one of the most talked-about peptides in the recovery and longevity space. First principles (this matters) Peptides are short chains of amino acidsāthe same building blocks your body already uses to make hormones, enzymes, neurotransmitters, and repair signals. They are better as an injectable because they are not broken down then by stomach acid whose, primary job is to break down proteins.... So⦠what is BPC-157? BPC-157 stands for Body Protection Compound-157. Itās a short chain of amino acids originally isolated from human gastric juice. Translation: your body already makes versions of this stuff to help protect and repair tissue, especially in the gut. Researchers noticed something interesting decades agoāthis peptide seemed to: - Support soft tissue repair (tendons, ligaments, muscle) - Promote angiogenesis (new blood vessel formation = healing fuel) - Support gut integrity and inflammatory signaling balance That combo is why it became popular in sports medicine, injury recovery circles, and functional medicine conversations. What does the science actually say? Most of the data we have comes from animal and pre-clinical studies. In those models, BPC-157 showed: - Faster healing of muscle, tendon, and ligament injuries - Protective effects in the GI tract - Modulation of nitric oxide pathways (important for blood flow and repair) Human data is still emerging.... ā ļø āResearch peptideā vs 503B pharmacy sourcing This is where people get tripped up. Research peptides: - Often labeled āfor research use onlyā - Not intended for human administration - Variable purity, stability, and sterility - No meaningful regulatory oversight 503B outsourcing pharmacies: - FDA-registered facilities - Subject to GMP (Good Manufacturing Practice) standards - Batch testing, sterility testing, and quality controls - Designed to reduce risk when compounds are used under medical supervision
