Federal health advisers are meeting to review a group of controversial chemicals called peptides. The unapproved injections have become a popular wellness trend, promoted by influencers and celebrities for building muscle, healing injuries and other uses.

A FDA advisory committee will review evidence surrounding peptides. Experts are concerned there is a paucity of evidence to back their approval for legal compounding.

The FDA could decide whether to loosen rules around peptide production this week. Some telehealth players are already seeing dollar signs.
