As U.S. shifts peptide rules, these are the risks experts want you to know

The U.S. government is set to permit certain specialty pharmacies to manufacture peptides, a class of drugs that have gained traction in the wellness industry. Health Secretary Robert F. Kennedy Jr., who has long advocated for peptides, has called for an end to the FDA's crackdown on these substances. However, as peptides become more popular due to self-prescribed "wellness influencers," experts are raising concerns about their targeted uses, potential side effects, and the social media trend surrounding them.

Peptides are short chains of amino acids that trigger hormones within the body, playing a role in growth, metabolism, and healing. They have been used in medicine for years, with insulin being a prime example. Synthetic peptides, created in a lab, mimic the body's natural cell communications. Most synthetic peptide drugs are administered through injections.

The main concern with expanding the sale of peptides in the U.S. is the process of compounding, which involves pharmacies creating drugs from scratch. This can lead to contamination, allergic reactions, and tumor growth, according to the FDA. Compounding is not intended to circumvent regulations, but experts worry that many people are purchasing peptides online from wellness companies without proper regulation.

The FDA has previously listed several injectable peptides, including BPC-157, as too risky for compounding. However, BPC-157 and other peptides can be brought into the country from countries like China, labeled as "not for human use." While some experts argue that peptides have potential benefits, they caution that there is insufficient evidence to support their safety and effectiveness for various conditions.

Health Canada has also issued warnings about unauthorized peptide drugs, highlighting potential risks such as infections, allergic reactions, and drug interactions.
