  • Vitamin and hydration IV drips · listed as “Vitamin IV therapy; Methylene Blue IV therapy”UNPROVEN
  • Hyperbaric oxygen therapy · listed as “Hyperbaric Oxygen Therapy (HBOT)”DEPENDS ON USE

    Regulator note. In July 2021 the FDA warned that some centres promote hyperbaric oxygen for uses it has not cleared or approved, such as cancer, autism and Alzheimer's disease, and advised using an accredited facility. FDA consumer bulletin, 26 July 2021

In April 2026 the FDA moved BPC-157 and 11 other peptides out of its group of compounding substances that raise significant safety risks, but kept its warning that compounded BPC-157 may cause immune reactions.
