The breadth of effective administration routes is unusual for a peptide and is part of why BPC-157 attracts ongoing interest in connective tissue
Proper peptide storage and handling prove essential, with lyophilized peptides requiring storage at -20C or lower (optimally -80C) away from bright light and moisture, and peptides containing cysteine, methionine, or tryptophan requiring additional protection from oxidation through anaerobic storage conditions to maintain stability and biological activity throughout experimental protocols
