In July 2026, a U.S. Food and Drug Administration (FDA) advisory committee voted to recommend six peptides for possible inclusion on the agency’s 503A Bulks List. Some people may have wondered whether the vote meant the peptides were FDA-approved or proven safe. It did not.

With many women hunting for additional treatment for menopausal symptoms, easier access to peptides seemed to signal hope. But doctors have a warning. There is limited evidence that these particular peptides are safe or effective for the uses being promoted.

What Are Peptides?

Peptides are short chains of amino acids, which are the building blocks of proteins. According to Jumana Al-Deek, M.D., owner of Med Method Direct, peptides help regulate various processes in the body. Your body naturally contains more than 7,000 peptides.

You’re probably familiar with some peptide-based medicines. Insulin and medications such as semaglutide and tirzepatide are examples of peptide medications that have been clinically tested and approved by the FDA.

Peptide medications such as semaglutide are different from topical peptides used in skincare products. Topical peptide products marketed as cosmetics, including those used to support collagen production, generally do not require FDA approval before they are sold.

Peptide products marketed as drugs are regulated differently, although compounded drugs themselves are not FDA-approved. Drug products containing peptides generally fall under a different category and require FDA approval before they can be commercially marketed. Compounded peptide products follow separate compounding rules.

Is Compounding Safe?

Many of these peptides remain largely unproven, and compounded drugs carry additional considerations. Compounded drugs are not FDA-approved, which means the FDA does not review their safety, effectiveness, or quality before they are marketed. Oversight also differs depending on the type of compounding facility.

“My foremost concern is where they are sourcing ingredients, contaminants, and the risk of infection,” Dr. Noble said. “Even if they are not contaminated or have heavy metals, they may not necessarily be safe. When things are made in a lab, quality control is a leap of faith.”

Instead of seeking compounded peptides, Noble and Al-Deek encourage women to talk to their providers about their symptoms to determine whether a proven solution already exists.

“My first question would be what are we trying to treat, and what human clinical trial evidence shows that this specific peptide is effective in menopausal women?” Al-Deek said.
