What peptide therapy means
Peptides are small proteins your body makes and uses as signals. Medicines built on peptides include insulin and GLP-1 drugs like semaglutide, which have defined, FDA-approved uses.
The same word is also used for products marketed for injury recovery, anti-aging, sleep or focus. Those products usually lack FDA approval and large human trials, so evidence for one doesn't carry over to another.
Three kinds of products sold as peptides
| Type | What it is | FDA review |
|---|---|---|
| FDA-approved peptide drugs | Brand or generic medicines with approved uses | Reviewed for safety, effectiveness and quality |
| Compounded peptides | Made by a pharmacy for an individual prescription | Not FDA-approved or reviewed before marketing |
| "Research use only" peptides | Sold as chemicals, not for human use | Not reviewed for human use |
What FDA says about safety
FDA's page on bulk substances that may present significant safety risks in compounding notes concerns such as immune reactions and limited human safety data for peptides including BPC-157, TB-500, CJC-1295 and ipamorelin. Ipamorelin is in that page's main risk table (category 2). BPC-157, TB-500, CJC-1295 and several others are in its table of nominations that were withdrawn, with FDA's safety notes; a withdrawn nomination is not FDA approval or a finding of safety. In July 2026 an FDA advisory committee reviewed BPC-157, KPV, TB-500, MOTs-C, Semax, Epitalon and emideltide for possible use in pharmacy compounding. An advisory committee review is not a final FDA decision, so check FDA's pages for the current status of any specific peptide.
FDA also says compounding should serve patients who can't be treated with an FDA-approved medication.
Questions to ask before you start
- What is the exact product and why this one for me?
- What evidence in humans supports it, and how strong is it?
- Who prescribes, who dispenses, and is the pharmacy state-licensed?
- What monitoring and lab work are planned?
- What does it cost over the full course?
How Gabriel approaches peptides
Gabriel does not recommend using peptides without a licensed clinician's supervision, and Gabriel never gives peptide dosing. Gabriel makes no claims for peptides beyond what verified evidence supports. Clinicians reviewing requests through Gabriel don't prescribe research peptides such as BPC-157, TB-500 or epitalon. Some peptide medicines, such as semaglutide and tirzepatide, can be prescribed through Gabriel by licensed clinicians at our telehealth partners. If you ask about one, a licensed clinician reviews your request and decides whether it's appropriate.
Compounded medications aren't FDA-approved. A licensed clinician decides what's right for you.
Common questions
What is peptide therapy?
A broad label for care using peptides. It covers FDA-approved drugs, compounded preparations and unapproved products, which differ in evidence and safety.
Is peptide therapy safe?
It depends on the product. FDA has noted safety concerns in compounding, such as immune reactions and limited human safety data, for several popular peptides, including BPC-157 and TB-500.
Is peptide therapy FDA-approved?
Some peptide drugs are, like GLP-1 medicines for their approved uses. Most products marketed as peptide therapy for recovery or longevity are not.
Does Gabriel give peptide dosing?
No. Gabriel never gives peptide dosing and does not recommend using peptides without a licensed clinician's supervision.
How much does peptide therapy cost?
It varies with the product, visits, labs and length of the course. See peptide therapy cost.
