FDA staff had recommended against including emideltide, which is used for insomnia and opioid withdrawal, on the list in part because studies on its efficacy are limited and because there are alternative therapies available to treat those conditions
Lyophilisation, or freeze-drying, is a process used to preserve the peptide, resulting in a solid puck of lyophilised powder that is reactivated through reconstitution

In animal models, BPC-157 has demonstrated remarkable properties across multiple organ systems: Tissue repair: Accelerates healing of muscles, tendons, ligaments, bones, and skin (Sikiric et al., 2018) Gastrointestinal protection: Protects and heals the gut lining, reduces intestinal inflammation, and counteracts NSAID-induced damage (Sikiric et al., 2016) Anti-inflammatory effects: Reduces systemic inflammation and modulates inflammatory cytokine expression Angiogenesis: Promotes new blood vessel formation, improving blood flow to injured tissues (Hsieh et al., 2017) Neuroprotection: Shows protective effects on the central and peripheral nervous system in animal models Nitric oxide modulation: Interacts with the nitric oxide (NO) system to support vascular health and tissue perfusion The peptide is sometimes called a healing peptide because of its broad tissue-protective properties

Because of the 0.9% benzyl alcohol, bacterial growth is inhibited , so the opened vial remains sterile for multiple transfers (usually up to ~28 days if kept sealed and refrigerated)
Weaknesses in Existing Clinical Literature The available clinical literature on BPC-157 is sparse and fraught with methodological weaknesses
Although according to some studies on binding of various drug to BSA, the efficiency of drugs to quench BSA fluorescence varies with changes in distance between bound drug and tryptophan
