Weight management
A sourced guide to GLP-1 and weight-management medication categories: approved uses, off-label prescribing, compounded products, FDA concerns and questions for a clinician. Not medical advice.
Clinical services are not available yet. GetPeptides has not launched medical visits, prescriptions or pharmacy delivery in any state. Nothing you do here enrolls you in treatment.
Educational information only — not medical advice. A consultation with a licensed clinician never guarantees a prescription, and treatment decisions are made independently between you and your clinician.
This page is editorial content written by the GetPeptides team from the publicly available regulatory sources cited below. It has not been reviewed or approved by a qualified independent clinician or pharmacist, and it is not medical advice.
FDA-approved medications
Several prescription medications are FDA-approved for chronic weight management in specific patient groups. Approval means the FDA reviewed evidence of safety and effectiveness for a defined use. Whether any approved medication is appropriate for you is a decision for a licensed clinician who has evaluated you.
Off-label use
Clinicians may sometimes prescribe an approved medication for a use the FDA has not specifically approved. This is legal and common in medicine, but the evidence base for the off-label use can be thinner than for the approved use.
Compounded medications
Compounded drugs are prepared under section 503A (by a licensed pharmacy for an individual patient with a patient-specific prescription) or section 503B (by an FDA-registered outsourcing facility). Neither pathway is FDA approval, and the FDA does not review these products for safety, effectiveness or quality before they reach patients. The FDA has stated compounded GLP-1 products should generally be used only when an approved drug cannot meet a patient's needs.
Investigational or unapproved substances
Some substances discussed online are not approved for human use at all and do not have lawful compounding eligibility established by this website. Products labeled 'research use only' are not legal to sell for human treatment and have not been reviewed for safety or effectiveness in people.
Risks and limitations
All medications carry risks, side effects, interactions and contraindications that differ from person to person. Results vary. No medication is a substitute for an individualized medical evaluation, and no evaluation guarantees a prescription.
Does an approved GLP-1 medicine make every version FDA-approved?
No. The FDA’s notice on unapproved GLP-1 drugs used for weight loss distinguishes approved medicines from unapproved versions. Unapproved versions do not undergo FDA review for safety, effectiveness and quality before marketing. A familiar medication name does not establish that a particular product is FDA-approved. Compounded products are not FDA-approved, even when discussed alongside an approved medicine.
When does the FDA say compounding can meet a need?
The FDA’s compounding questions and answers explain that compounding can address a patient’s medical need that an approved drug cannot meet. The FDA says compounded drugs should only be used in patients whose medical needs cannot be met by an FDA-approved drug. That is not a blanket endorsement of compounded weight-loss products, and this guide does not establish anyone’s eligibility or a product’s legal compounding status.
Is off-label prescribing the same as compounding?
No. Off-label use concerns how an approved medication is prescribed for a use that is not specifically FDA-approved. Compounding concerns preparation of a drug that is not FDA-approved. These are different questions: whether a product is approved, whether the intended use is approved, and whether a compounded preparation complies with applicable requirements. An off-label use does not turn a compounded product into an approved medicine.
What questions can I bring to a licensed clinician?
Ask which exact product is being discussed, whether it is FDA-approved for the proposed use, and where to read its official information. If compounding is discussed, ask what medical need an approved product cannot meet and which licensed pharmacy would prepare it. Ask about individual risks, interactions and follow-up rather than relying on online results or promises. These are discussion prompts, not treatment instructions; GetPeptides does not provide dosing, personal eligibility assessments or prescriptions, and clinical services are not available here yet.
