However, the most important advantage is the very safe profile of BPC (the lethal dose (LD1) could be not achieved) (Seiwerth et al., 2018), emphasized in terms of its physiological role (assessed using in situ hybridization and immunostaining for BPC 157 in the human gastrointestinal mucosa, lung bronchial epithelium, the epidermal layer of the skin, and kidney glomeruli) (Seiwerth et al., 2018)
Because of its broad experimental research profile, BPC-157 has become one of the best-known peptides in musculoskeletal and regenerative biology
Muscle Building : Peptides can also promote muscle growth by encouraging the production of proteins that help build muscle fibers, improving strength and recovery

Some protocols use five days on, two days off schedules to prevent possible receptor desensitization, though evidence for this approach is limited
