A booming wellness market has formed around peptides—mini-proteins that affect various processes inside the body. They help regulate hunger, blood sugar, inflammation, tissue repair, sleep and hormone release, among other bodily functions. Synthetic versions are sold as injections, pills, nasal sprays and creams. Some, including insulin and GLP-1 drugs, have been rigorously tested and approved by the FDA and are sold by prescription. But many wellness peptides lack credible evidence of safety or effectiveness, yet are available online.

Every transformative technology has its prophets of doom. AI is just the latest to draw them out.

The United States once defeated a ravenous, parasitic fly with mass releases of sterile insects. A genetically engineered strain could strengthen that defense, while CRISPR gene drives remain a more contentious possibility.

The flesh-eating New World screwworm (NWS)—a parasitic fly whose maggots feed on the living tissues of warm-blooded animals—has returned to the United States, creating a challenging agricultural biosecurity emergency across the ranchlands, border corridors, and wildlife habitat of Texas and New Mexico.

During a meeting last week [July 23-24], the Food and Drug Administration's Pharmacy Compounding Advisory Committee recommended that six previously restricted peptides be made available for pharmacy compounding.

Peptides are short chains of amino acids, the building blocks of proteins. Compounding is the preparation of customized medications for individual patients rather than the dispensing of conventionally manufactured, FDA-approved drugs.

The committee endorsed BPC-157, KPV, TB-500, MOTS-c, Epitalon and Semax—substances promoted for conditions ranging from ulcerative colitis and wound healing to obesity, osteoporosis, insomnia and neurological disorders. Only emideltide was rejected, 7-6.
