Compounded peptides vs. "research" peptides

Search for almost any peptide and you’ll find two very different kinds of sellers: telehealth services that work with licensed pharmacies, and websites selling “research peptides.” They can look similar online. They are not the same thing.

What "research peptides" are

Research peptides are sold as laboratory chemicals, usually labeled “for research use only” or “not for human consumption.” Because they’re sold as chemicals rather than medications:

• •No prescription or medical review is involved
• •They are not prepared by a licensed pharmacy
• •Purity, strength and sterility are not independently verified for human use
• •Labels may not match what’s in the vial
• •There’s no provider to call about side effects

Some sellers include a certificate of analysis. That’s a document the seller supplies about a batch, not an inspection by a pharmacy board or the FDA.

What compounded peptides are

A compounded peptide is a medication prepared by a licensed pharmacy for one patient, based on a prescription from a licensed provider. That means:

• •A provider reviews your history and decides it’s appropriate
• •A state-licensed pharmacy prepares it under pharmacy quality standards
• •It’s labeled for you, with directions from your provider
• •You have a care team to contact with questions

Compounded peptides are not FDA-approved either. The difference is the chain of professional responsibility: a prescriber, a licensed pharmacist, and the rules that govern both.

Why it matters

Injectable products in particular need to be sterile and accurately dosed. A contaminated or mislabeled vial can cause infections or unexpected effects. Using a product labeled “not for human consumption” also means no one has taken responsibility for whether it’s suitable for a person.

How to tell the difference

• •Does anyone ask about your health before you can buy? A legitimate service requires an intake and a provider’s review.
• •Is a licensed pharmacy named or available on request?
• •Does the label say “for research use only”? If so, it isn’t intended for people.
• •Is there a care team you can reach?

Compounded medications are not approved by the FDA and have not been evaluated by the FDA for safety, effectiveness or quality. All prescriptions require evaluation and approval by a licensed healthcare provider.
