Compounded Semaglutide: 2025 Safety & Legal Guide

Compounded semaglutide use surged during GLP-1 shortages and insurance denials. Now that supply is stabilizing and enforcement timelines have changed, the big questions are: Is compounded semaglutide still legal? Is it safe? And how do you lower your risk if you’re considering it?

Quick answer (what most people are searching for):

• Legality: Routine compounding of semaglutide injections that copy approved drugs (Ozempic/Wegovy) is no longer allowed now that the national shortage is resolved. Only limited, patient‑specific compounding may be appropriate under strict state/federal rules (FDA policy update on compounding).
• Safety: Compounded semaglutide is not FDA‑approved. FDA has warned about dosing errors, salt forms (sodium/acetate) that aren’t equivalent, and quality issues/counterfeits. As of July 31, 2025, FDA had received 605 adverse‑event reports linked to compounded semaglutide (FDA safety page on unapproved GLP‑1 products).
• What to do: If you must consider compounding, work with a licensed prescriber and NABP‑verified pharmacy, insist on semaglutide base (not salts), and get clear dosing instructions. Avoid any site selling “generic Ozempic” or shipping without a prescription (NABP Safe Site Search tool).

This guide summarizes the latest FDA updates, safety signals, and practical vetting steps for patients, clinicians, and clinic operators.

What is compounded semaglutide—and how is it different?

Compounded semaglutide is a custom preparation made by a pharmacy to meet an individual patient need when an approved product can’t—like a true allergy to an inactive ingredient. It is not the same as Wegovy, Ozempic, or Rybelsus, and there are no FDA‑approved generics. Regulators and the manufacturer have reported that some compounded products contained impurities, inconsistent doses, or even no active semaglutide (FDA safety page on unapproved GLP‑1 products; Novo Nordisk patient‑safety notice on compounded semaglutide).

2025 legal status and enforcement timelines (what changed)

• FDA declared the national shortage of semaglutide injection resolved on February 21, 2025 (FDA policy update on compounding).
• With shortages resolved, FDA narrowed enforcement discretion for compounding semaglutide injections that are “essentially copies” of approved drugs:
  • Section 503A (state‑licensed pharmacies/physicians): enforcement discretion ended April 22, 2025 (FDA policy update on compounding).
  • Section 503B (outsourcing facilities): enforcement discretion ended May 22, 2025 (FDA policy update on compounding).
• FDA may act at any time for quality, safety, or other violations—regardless of shortage status.

Implication: Routine compounding of semaglutide injections as copies of approved products is no longer allowed. Limited, patient‑specific compounding may still occur under strict conditions (e.g., a documented need that approved products cannot meet) and state/federal law.

Safety snapshot: the risks FDA and state boards are flagging

The FDA’s summary of concerns around unapproved GLP‑1 products details the following risks (FDA safety page on unapproved GLP‑1 products):

• Adverse events: 605 reports tied to compounded semaglutide as of July 31, 2025 (and 545 for compounded tirzepatide), with likely underreporting.
• Salt forms: Semaglutide sodium/acetate salts should not be used; they aren’t known to be equivalent to the approved active ingredient (semaglutide base).
• Dosing errors: Multi‑dose vials and unclear instructions have led to miscalculations and overdoses (sometimes 5–20×), causing ER visits and hospitalizations.
• Contamination/quality: Quality problems include improper shipping/storage and unqualified suppliers; state boards, such as the Alabama Board of Medical Examiners, have issued specific warnings about improper compounding and predatory practices (Alabama Medical Board advisory).
• Counterfeits/fraud: Fraudulent labels, non‑prescription sales, and unlicensed online sellers remain an ongoing risk.

Clinician note: Professional groups and managed-care sources generally advise preferring FDA‑approved options. If compounding is considered, use NABP‑verified pharmacies and robust counseling to reduce dosing errors (AJMC provider guidance on compounded semaglutide).

Compounded vs FDA-approved semaglutide: quick comparison

Who might consider compounding—despite the risks?

• A documented, patient‑specific need that an approved product cannot meet (e.g., true excipient allergy), determined by a licensed prescriber under state and federal law. Routine cost‑driven substitution is not an allowed basis once a drug is commercially available (FDA policy update on compounding).
• In any case, avoid salt forms of semaglutide and non–FDA‑registered sources; obtain prescriptions from licensed clinicians and fill at state‑licensed pharmacies (FDA safety page on unapproved GLP‑1 products).

Pharmacy vetting checklist (patients and providers)

Use these steps before you buy or refer:

1. Verify licensure and accreditation
   • Confirm the pharmacy is state‑licensed where you live and where it operates; prefer NABP Digital Pharmacy Accreditation or Healthcare Merchant Accreditation (NABP Digital Pharmacy Accreditation program).
   • Use NABP’s Safe Site Search or look for a .pharmacy domain indicating verification (NABP Safe Site Search tool).
2. Confirm legitimate sourcing and formulation
   • Ask whether the API is semaglutide base (not sodium/acetate) from FDA‑registered suppliers, and request certificates of analysis.
3. Demand sterility and potency testing
   • For injectables, require batch sterility and potency testing and ask how stability/shelf life is established.
4. Require real clinical support
   • Ensure the pharmacy provides pharmacist counseling and clear, written dosing instructions.
5. Avoid red flags
   • “No prescription required,” “generic Ozempic,” crypto‑only payments, extreme discounts, damaged packaging, or hidden contact info.

Dosing and administration: why compounded vials raise error risk

Most adverse‑event clusters involve dosing errors with multi‑dose vials—drawing the wrong volume, misreading units, or escalating too quickly. Prefilled pens reduce this risk via dose selectors and standardized training, which compounded versions often lack. If a prescriber believes compounding is necessary, require:

• A clear titration plan that mirrors evidence‑based increments and max weekly doses; avoid unproven strategies like “microdosing” or rapid up‑titration without medical oversight. For context on standard schedules, see our Wegovy dosing guide.
• A pharmacist‑taught injection walkthrough and a written syringe conversion chart.
• A follow‑up plan for side effects and missed doses.

Body composition matters on GLP-1s—avoid losing muscle while you lose fat

GLP‑1s can drive meaningful fat loss—but rapid weight loss without enough protein and resistance training can trim lean mass too. Think of lean mass as your engine; you want a smaller fuel tank, not a smaller engine.

A DEXA scan quantifies fat, lean tissue, bone density, and visceral fat so you can steer your plan in real time. Start with a baseline scan, recheck every 8–12 weeks, and adjust training and nutrition if you see lean mass sliding. You can book a DEXA scan to track these changes at the BodySpec booking page.

Safer access alternatives now that shortages are over

Given the legal and safety risks of compounding post‑shortage, consider these steps before pursuing a compounded route:

• Appeal insurance denials with medical documentation, especially for FDA‑approved indications; ask about step therapy and prior auth criteria.
• Check manufacturer savings programs and pharmacy availability for approved brands; semaglutide injection supply is stabilized nationally as of February 2025 (FDA policy update on compounding).
• If an approved GLP‑1 still isn’t feasible, discuss alternatives or interim options with your clinician. Avoid purchasing from unverified online sellers—NABP reports that most websites offering prescription‑only drugs operate illegally, often without prescriptions or proper licensure (NABP Safe Site Search tool).

For clinics and providers: a concise compliance roadmap

• Screen for non‑indicated use against FDA‑approved labeling for GLP‑1s (e.g., chronic weight management indications) and key contraindications (e.g., history of medullary thyroid carcinoma or MEN 2, pregnancy).
• Document medical necessity and prior authorization attempts where applicable (AJMC provider guidance on compounded semaglutide).
• Restrict compounding referrals to verified, licensed pharmacies — prohibit salt forms and insist on semaglutide base from FDA‑registered sources.
• Create dosing SOPs (titration, maximums, missed doses) and patient education modules — reduce vial/syringe errors.
• Implement AE monitoring and MedWatch reporting — set return‑to‑clinic triggers for GI side effects, hypoglycemia risk in patients on sulfonylureas/insulin, and suspected contamination.
• Track outcomes with objective measures — DEXA for body composition and visceral fat, A1c for glycemic control, and waist circumference. Share progress visuals to sustain adherence.

FAQs

• Is compounded semaglutide legal now?
  Generally not for routine use as a copy of approved drugs, since the national shortage is resolved; limited, patient‑specific scenarios may remain under 503A/503B with strict conditions (FDA compounding policy update).

• Is compounded semaglutide safe?
  Safety is uncertain; products aren’t FDA‑reviewed. FDA has flagged salt forms, overdoses, quality issues, and counterfeit risks and has documented hundreds of adverse events (FDA safety page on unapproved GLP‑1 products).

• Are sublingual, ODT, or nasal “semaglutide” options proven?
  No. Manufacturer communications warn that non‑injection compounded forms lack evidence for absorption or effectiveness (Novo Nordisk patient‑safety notice on compounded semaglutide).

• How can I spot a rogue online seller?
  Beware of “generic Ozempic,” no‑prescription offers, crypto‑only payments, extreme discounts, damaged packaging, and hidden contact info. Verify with the Safe Site Search Tool or look for a .pharmacy domain (NABP Safe Site Search tool).

• What about tirzepatide compounding?
  Similar enforcement discretion timelines applied as shortages resolved; see FDA for current status and restrictions (FDA compounding policy update).
