Standard oral glutathione is susceptible to gastrointestinal peptidase cleavage, limiting absorption from single doses

Most peptides are degraded rapidly in the gut, but BPC-157's sequence resists this breakdown, enabling meaningful gastrointestinal research protocols

They also require a trip to the doctor's office or clinic, which can be inconvenient for some people

Finally, NO has been shown to induce the inhibition of low density lipoprotein (LDL) oxidation that is implicated in the early stages of atherosclerosis [72]
