BPC-157, AOD-9604, and MOTS-c are widely studied research peptides that have gained attention for their potential roles in bone density maintenance, tissue recovery, and regenerative processes. Each peptide operates through distinct biological pathways, making them valuable subjects in laboratory and experimental research focused on musculoskeletal health and cellular repair. BPC-157 (Body Protection Compound-157) is a synthetic peptide derived from a naturally occurring gastric protein. Research suggests it may play a role in supporting angiogenesis, collagen formation, and cellular signaling involved in tissue regeneration. In scientific models, BPC-157 has been examined for its potential influence on bone healing, connective tissue integrity, and recovery following mechanical stress or injury.
