Current FDA Status

As of 2026, BPC-157 and TB-500 (Blend) are not approved by the U.S. Food and Drug Administration (FDA) for any medical use. These peptides are categorized under research-only substances, meaning they are legally available solely for scientific and laboratory research purposes. The FDA has not listed these peptides on its bulk drug substance list for compounding, categorizing them as Category 2 substances, which are not eligible for compounding due to insufficient safety and efficacy data (Federal Register Notice).

Compounding Status

According to FDA guidelines, peptides not listed in Category 1 of the bulk drug substance list cannot be compounded by either 503A or 503B pharmacies. BPC-157 and TB-500 (Blend) fall under Category 2, which indicates a lack of sufficient data to support their safety and efficacy for compounding. This restriction is part of the FDA's efforts to regulate and ensure the safety of compounded medications (FDA Compounding Guidelines).

Enforcement Actions

The FDA and the Department of Justice (DOJ) have taken significant enforcement actions against entities involved in the illegal sale and distribution of BPC-157 and TB-500 (Blend). In 2025, the FDA issued multiple warning letters to companies marketing these peptides as dietary supplements or unapproved drugs. Additionally, the DOJ prosecuted several cases where individuals were charged with selling these peptides for human use, resulting in fines and criminal charges.

Prescription vs. Over-the-Counter vs. Research Use

Legally, BPC-157 and TB-500 (Blend) can only be purchased for research use. This means they cannot be prescribed by healthcare providers or sold over-the-counter for human consumption. "Research use only" indicates that these peptides are intended for laboratory research and not for diagnosing, treating, or preventing any disease in humans or animals (FDA Research Use Guidelines).

State-Level Variations

While federal regulations are clear, some states may have additional restrictions or enforcement actions related to the sale and use of research peptides. It's essential for researchers and clinics to be aware of and comply with both federal and state regulations to avoid legal repercussions.

What "Off-Label" Actually Means

The term "off-label" refers to the use of an FDA-approved drug for an unapproved indication. Since BPC-157 and TB-500 (Blend) have never received FDA approval, prescribing these peptides is not off-label; it is prescribing an unapproved drug, which is not permissible under current FDA regulations.

What This Means for Patients

Patients considering peptide therapy should exercise caution and ensure they are working with clinics that comply with legal standards. Verify that the clinic is not offering unapproved peptides for therapeutic use and be wary of any provider claiming to sell these peptides for anything other than research purposes. Red flags include clinics that do not disclose the regulatory status of the peptides they offer or make unsubstantiated claims about their efficacy.

Legal Alternatives

For patients seeking peptide therapies with similar benefits, it may be worth exploring FDA-approved alternatives or those in advanced clinical trials. Peptides such as semaglutide have undergone rigorous testing and have clear regulatory pathways.
