It is worth being clear here: in people with normal B12 levels, injections have not been shown to improve athletic performance or endurance
Additionally, people with certain medical conditions that impair nutrient absorption, like Crohns disease or pernicious anemia, may find these injections particularly helpful
BPC-157 is a synthetic peptide supplied as a lyophilized research compound for scientific investigation involving cellular signaling pathways, tissue-model analysis, and peptide interaction studies within controlled laboratory environments
The side effect I watch for most carefully isnt on either list
TB-500 has even less human research than BPC-157
However, many people who are deficient are simply this way because their bodies are unable to absorb Vitamin B12 efficiently
