What are peptides?
Amino acids are the building blocks of proteins. A peptide is a short chain of them; a protein is a long one. Your body makes many peptides of its own, including some hormones.
Because peptides act as signals in the body, drug makers have developed some into medicines. Insulin and the weight-loss medicines semaglutide and tirzepatide are examples of peptide-based medicines that are FDA-approved for specific uses.
Why “peptide therapy” can be confusing
Online, “peptide therapy” often refers to products that are not FDA-approved medicines. They may be sold as compounded drugs, as supplements or as “research chemicals” not meant for people. Claims made about them often come from laboratory or animal studies, and results there may not apply to people.
That is why the exact product matters more than the word “peptide”. Two products with similar names can have very different evidence, quality and risks.
Questions to ask before trying a peptide
- What exactly is the product, and what is it meant to treat?
- Is it FDA-approved for my situation, or compounded, or neither?
- Who makes it, and where does it come from?
- What evidence is there in people, not only in animals?
- What are the possible side effects, and what is still unknown?
- How would I be monitored, and for how long?
- What are my other options?
If a seller can’t answer these clearly, that is worth noticing.
Possible risks
Risks depend on the product. They can include reactions where an injection is given, allergic reactions, infection from contamination, and effects that are not yet known because a product has not been well studied in people. The FDA has listed certain peptide substances as possibly presenting significant safety risks when compounded.
Call 911 for swelling of the face or throat or trouble breathing. Get medical care right away for redness, warmth, swelling or pus where an injection was given, especially with a fever.
