Are peptides regulated by FDA?
William Smith
Updated on March 30, 2026
FDA considers any polymer composed of 40 or fewer amino acids to be a peptide. Peptides can occur naturally in the body or can be produced in a laboratory through chemical synthesis or recombinant DNA technology using other living systems (e.g., bacteria).
Which peptides are FDA approved?

How many peptides are FDA approved?
PEPTIDE DRUGS ON THE MARKET There are currently some 60-70 approved peptide drugs in the US, Europe and Japan, over 150 in active clinical development and 260 having been tested in clinical trials (Lau & Dunn, 2018).
Are peptides considered biologics?
Biologics are proteins or peptides which are synthesized from the set of 20 naturally occurring amino acids found in living organisms from bacteria to humans. Some sources consider molecules up to 100 amino acids as peptides.
Why are peptides not FDA approved?
Peptides are small polymers made up of 40 or fewer amino acids and are considered complex drugs, in part because some peptide products may vary in the length and sequence of their component amino acids, and also because the products often have accompanying impurities which may be difficult to characterize, according to …
Is CJC 1295 FDA approved?
In other words, popular peptides that a ton of folks in the functional medicine, health, and fitness space use—such as CJC 1295, Ipamorelin, Selank, Semax, and many others—are no longer able to be legally prescribed by doctors.
Are peptides legal in the US?
A peptide is a short chain of amino acids joined together by a bond and is used to increase the body’s production of the growth hormone. It is illegal to buy and use peptides for purposes other than research.
Is an amino acid a biologic?
Amino acids can also be basic, like lysine, or acidic, like glutamic acid. The sequence and interactions between the side chains of these different amino acids allow each protein to fold into a specific three-dimensional shape and perform biological functions.
Why did the FDA ban Ipamorelin?
“The products are being recalled due to a lack of assurance of sterility. These concerns arose following a routine inspection of the pharmacy by FDA,” stated the company-written, FDA-posted recall notice.
Are peptides legal to buy in the US?
What peptides are illegal?
Ipamorelin and Sermorelin – both peptides with anabolic effects, which are both prohibited by WADA. Follistatin – Promotes muscle growth. Banned by WADA, with its possession without legal authority is illegal. Thymosin – Used to speed up recovery from injury, it is an unregulated substance banned by WADA.
What is the FDA’s peptide drug product evaluation process?
When a peptide drug product application is submitted to the FDA, it is the responsibility of the applicant to provide evidence that the peptide product under evaluation is safe, effective, and of high quality.
What should be included in an NDA for a peptide product?
In addition to the general CMC information as outlined above, an NDA for a peptide product should also include specific data capturing quality factors that affect the safety (including immunogenicity) of the peptide. 2
Is one size fits all in peptide analysis?
This is not a “one size fits all” approach, but rather a case-by-case analysis depending on factors characteristic of each different peptide. 2
What are the FDA’s requirements for reference standards?
Kennett of the FDA stated that regulatory authorities require that reference standards be suitable for their intended purposes, well characterized, qualified, and stable. She strongly recommended that appropriate protocols for manufacture and qualification of reference standards be in place.
