GLP-1 Transition
You're losing compounded access. Here is the whole menu.
Every other page on this subject is published by someone with something to sell you — a clinic, a pharmacy, a telehealth platform, a manufacturer. This one sells nothing and links to no seller. What follows is what changed, what is still legal, what each option really costs once you read the terms, and what the trials say happens if you stop.
Start here: the headline is wrong
You have probably read that the FDA is “banning” compounded GLP-1s, or that it “removed” or “excluded” semaglutide, tirzepatide and liraglutide from the 503B Bulks List. Three claims, and all three are wrong.
It is a notice — 91 FR 23431, published May 1, 2026. A notice proposes and invites comment. It does not carry the force of a rule, and as of September 25, 2026 FDA has not published a final determination.
The proposal is not to include the three on the 503B Bulks List. None of them was ever on it. You cannot be removed from a list you were never on — and a surprising number of law-firm alerts, trade outlets and FDA's own press headline say “exclude” anyway. The distinction matters because it tells you what the action can and cannot reach.
Mass-market compounded GLP-1 ended in 2025, when FDA resolved the shortages and the enforcement-discretion windows shut — the last on May 22, 2025. The 2026 proposal concerns a different door: whether outsourcing facilities could compound these drugs from bulk ingredients when there is no shortage. It leaves the shortage route alone — section 503B separately allows compounding from bulk while a drug is on FDA's shortage list, as the notice itself says — so a future shortage would open that route again. If your supply ended recently, the cause was more likely your provider winding down than any 2026 action.
Corrected October 1, 2026: this paragraph and the May 1 timeline entry previously said the proposal closes the route a future shortage could have reopened. The notice (91 FR 23431) says the opposite: section 503B separately provides for compounding from bulk drug substances while the drug is on FDA's shortage list.
How it actually happened
-
2024-10-02
FDA declares the tirzepatide shortage resolved
The shortage listing was the legal hook for compounding a copy. Removing it starts the clock on everything that follows.
-
2025-02-18
503A enforcement discretion ends — tirzepatide
State-licensed pharmacies lose the routine route first.
-
2025-02-21
FDA declares the semaglutide shortage resolved
Declaratory order to Novo Nordisk. Same mechanic as tirzepatide.
-
2025-03-19
503B enforcement discretion ends — tirzepatide
-
2025-04-22
503A enforcement discretion ends — semaglutide
A federal court declined to halt this on April 24. The deadlines held.
-
2025-05-22
503B enforcement discretion ends — semaglutide
This is the date mass-market compounded GLP-1 actually ended. Not 2026.
-
2026-05-01
FDA proposes not to include the three on the 503B Bulks List
91 FR 23431. A notice, not a rule. It concerns compounding from bulk when there is no shortage; the notice itself says the shortage route is a separate provision of section 503B. (Corrected October 1, 2026.)
-
2026-06-26
Comment period extended to July 30
91 FR 38719. Requested by an outside group; FDA granted 30 of the 60 days asked.
-
2026-07-30
Comments closed, 11:59 p.m. ET
4,277 comments were posted to the notice. FDA said it would weigh them before publishing a final determination in the Federal Register.

2026-09-25
Still no final determination
The newest FDA document in the docket is the June 26 extension, and nothing later has appeared in the Federal Register. The notice gives no date for the decision.
503A and 503B are not the same thing
Almost every confusion about what is still legal comes from collapsing these two. They are different sections of the law with different permissions.
Compounds for one named patient against one prescription. Never depended on the Bulks List. The 503B proposal does not directly touch it. What ended routine 503A copying was the 2025 shortage resolution.
Registers federally and makes batches without patient-specific prescriptions. Needs the substance on the Bulks List, or the drug on the shortage list. Neither is true now — and the proposal would close the first permanently.
This is why “the FDA banned compounded semaglutide” misleads in both directions at once. It overstates what the 2026 notice does to your local 503A pharmacy, and it understates what already happened in 2025.
The full menu
Eight options, unranked and in no meaningful order, with prices as of September 25, 2026. We are not steering you to one, and we earn nothing whichever you pick. Prices were read from each manufacturer's own published terms on September 25, 2026. Every one includes the part the advertising leaves out.
Branded GLP-1 on your insurance
Commercial plan that covers obesity medication
›
Plan copay. Manufacturer savings cards can bring an eligible commercial copay to as little as $25/month; Wegovy's, Zepbound's and Foundayo's cards each cap the benefit at $100/month of savings, and Lilly's cards as written end December 31, 2026. Government beneficiaries are excluded from these cards by statute. Terms read September 25, 2026.
Coverage for obesity — as opposed to type 2 diabetes — is an employer-by-employer decision, and plenty of plans exclude it outright. Prior authorisation is normal. Ask about the indication, not the drug: the same molecule is often covered for diabetes and denied for weight.
“Is this covered under my plan for weight management, or only for diabetes? What does prior authorisation require, and how long does it take?”
Branded GLP-1, cash-pay direct from the manufacturer
Uninsured, or insured with no obesity coverage
›
Zepbound, through LillyDirect's Self Pay Journey Program, vial or KwikPen (and the KwikPen at retail with the self-pay savings card): $299 (2.5 mg), $399 (5 mg), $449 (7.5–15 mg). Wegovy, through NovoCare Pharmacy: $349/month (0.25–2.4 mg pen), $399 (HD 7.2 mg), and $199 for the two lowest doses for two fills if you are new to the offer, through December 31, 2026. Prices read September 25, 2026.
Two things the headline price hides. First, Zepbound's $449 is conditional: you must complete each refill within 45 days of your last delivery. Miss that window and the regular price applies — $499 at 7.5 mg and $699 at 10 mg and above, vial or pen alike, which is $250 a month more at the higher doses. A gap in supply is exactly what a transition produces, so this is the trap to plan around. Second, a "month" is 28 days, which is 13 fills a year, not 12 — and the retail KwikPen self-pay card covers at most 11 fills a calendar year. Needles and syringes are extra, and nothing you pay counts toward a deductible or out-of-pocket maximum.
“If I have a gap before my next fill, what price will I actually pay on the refill? Is the vial or the pen cheaper at the dose I'm heading for?”
An oral GLP-1
Anyone who would rather not inject
›
Wegovy pill, through NovoCare Pharmacy: $149/month at 1.5 mg, $199 at 4 mg (it was $149 until August 31, 2026) and $299 at 9 mg and 25 mg. Foundayo (orforglipron), self-pay through LillyDirect: $149 at 0.8 mg; $149 at 2.5 mg and $199 at 5.5 mg, both temporary cuts that end December 31, 2026 (regular $199 and $299); $299 at 9 mg; and $299 at 14.5 mg and 17.2 mg only if you refill within 45 days, $349 if you don't. Prices read September 25, 2026.
Both pills get more expensive as you titrate up, and Foundayo's top-dose price carries the same 45-day refill condition as Zepbound's. Foundayo was approved April 1, 2026. It is a small molecule rather than a peptide, taken any time of day with no food or water restriction — the oral semaglutide it competes with does have those restrictions. It is new, which cuts both ways: fewer long-term data, and no generic for years.
“Is an oral option reasonable at my dose and history, and what does switching molecules do to my titration?”
The Medicare GLP-1 Bridge
Medicare Part D enrollees who meet the clinical criteria
›
$50/month flat, total out-of-pocket. Launched July 1, 2026; runs through December 31, 2027. Price and dates re-read September 25, 2026.
It covers the Wegovy pen and pill, the Zepbound KwikPen and the Foundayo pill — not the single-dose Zepbound pens or vials. It sits outside the regular Part D payment flow, so the $50 does not count toward your deductible or your annual out-of-pocket cap, Extra Help cannot reduce it, and no coupon stacks on it. Prior authorisation is required, and the clinical criteria are assessed as of when you first started GLP-1 therapy — not today. KFF estimated roughly 3.8 million people qualify, about 8% of Part D. Beneficiaries have reported that the published eligibility copy and the prescriber criteria don't obviously agree on whether BMI 30 with prediabetes counts, so confirm rather than assume.
“Am I inside the Bridge criteria as they were at the time I started? Who submits the prior authorisation, and what happens when the programme ends in 2027?”
Medicaid
Medicaid enrollees
›
State formulary copay where it is covered at all.
Coverage for obesity is a state-by-state patchwork and is commonly gated behind BMI thresholds, documented lifestyle intervention and step therapy. Coverage for type 2 diabetes is far more widely available than coverage for weight. Your state is the only answer that matters here.
“Does my state's Medicaid programme cover this for weight management, and what does the prior authorisation require?”
Compounded GLP-1 through a 503A pharmacy
A narrow subset — and probably not you
›
Varies. Cost is not what makes it lawful.
This is the option most misunderstood right now, so be precise about it. 503A pharmacies never depended on the 503B Bulks List, so FDA's 503B proposal does not directly touch them. What ended routine 503A compounding was the shortage resolution back in 2025, which switched off the "essentially a copy" exception. What remains are narrow, patient-specific exceptions — a documented allergy to an inactive ingredient in the approved product, or a strength that simply is not commercially made — determined and documented by a prescriber for you. FDA has been explicit that affordability and insurance access do not constitute clinical need. Adding B12 or an amino acid to claim a "significant difference" is a known pattern and FDA has not accepted it.
“If you are offering me a compounded GLP-1, what is the documented clinical basis for it in my chart, and is this pharmacy 503A or 503B?”
Liraglutide
Rarely a first choice, but it is a live option
›
Generic liraglutide now exists — Meitheal launched the first in April 2025, Teva followed. Prices vary by manufacturer and pharmacy.
Liraglutide is daily rather than weekly and produces less weight loss than semaglutide or tirzepatide in trials. As of September 25, 2026 it is still carried on FDA's shortage list — generic presentations listed available, Victoza and Saxenda listed limited, and one Saxenda presentation posted as to be discontinued on August 25 — which is a live status that can change without notice. It is also the third drug in FDA's 503B proposal, which is the part most coverage leaves out.
“Is liraglutide a reasonable fit given my history, and can my pharmacy actually get it this month?”
Stopping
Anyone for whom the numbers above don't work
›
Nothing, which is exactly why it deserves the same scrutiny as the others.
Stopping is a legitimate choice and this page will not talk you out of it. It does insist you make it with the trial data in front of you rather than discover it. In the STEP 1 extension, people who had lost 17.3% of body weight regained about two-thirds of it within a year of stopping, and most of the cardiometabolic improvements drifted back toward baseline with it. In SURMOUNT-4, the group switched to placebo regained roughly 14%. Neither trial says a person is doomed — the semaglutide group was still 5.6% below baseline a year out — but both say the same thing: the effect is a function of the drug being present. Plan the landing rather than falling.
“If I stop, what should I be watching, and what does a maintenance plan look like without the medication?”
Want this narrowed to your situation? The transition planner filters the same menu by coverage and supply and hands you the questions to take to a prescriber. It recommends nothing, stores nothing and sends nothing anywhere.
If you stop, know what the trials found
This is the part worth reading before the price tables, not after. Two randomised trials withdrew the drug on purpose and measured what happened.
Mean loss was 17.3% at week 68. By week 120 — one year off the drug — participants had regained 11.6 percentage points, leaving them 5.6% below where they started. Most cardiometabolic improvements drifted back toward baseline alongside the weight.
After a 36-week lead-in averaging 20.9% loss, participants were randomised to continue or withdraw. At 88 weeks the continuing group was 25.3% down; the withdrawn group, 9.9%. A later analysis found that those regaining a quarter or more of their loss also gave back more of their blood-pressure, lipid and glycaemic gains.
Read them carefully and they say something narrower than “it all comes back.” The semaglutide group was still meaningfully below baseline a year later. What both trials establish is that the effect tracks the drug's presence — which makes stopping a decision to plan, with a prescriber, rather than an event that happens to you when a vial runs out.
The grey market is going to find you
When a legal supply closes and the replacement costs several hundred dollars a month, an unregulated one fills the gap. It is already advertising to you. We are not going to tell you where it is or how to use it — but leaving you to meet it uninformed would be its own kind of failure.
FDA has been explicit that semaglutide sodium and semaglutide acetate are not the same active ingredient as approved semaglutide, and that there is no lawful basis for using them in compounding. A product sold under a name that looks right is not automatically the substance in the trials.
It denotes material not intended for human use and not held to the manufacturing standards that phrase implies to a lay reader. It is not a compounding pathway and it is not a quality tier.
As of early 2025 FDA had received more than 455 adverse-event reports involving compounded semaglutide and more than 320 involving compounded tirzepatide. A recurring pattern was people drawing the wrong dose from a multidose vial, some badly enough to require hospitalisation. Reported via Pharmacy Times citing FDA.
An approved product carries a manufacturer accountable for identity, potency and sterility. Outside that chain there is no one to hold to it, and no recall mechanism when something is wrong.
Where the proposal stands
The comment window closed at 11:59 p.m. Eastern on July 30, 2026, on docket FDA-2018-N-3240, after one thirty-day extension granted at an outside group's request. FDA had asked specifically for comment on the clinical-need standard and on its own reasoning, and said it would weigh what it received before publishing a final determination in the Federal Register.
As of September 25, 2026 it has not. The newest FDA document in the docket is still the June 26 extension notice, nothing later has appeared in the Federal Register, and the notice itself gives no date for the decision. 4,277 comments had been posted to the notice, the most recent on August 24, 2026. FDA's stated basis is that there is no clinical need for outsourcing facilities to compound these three from bulk, and it has been explicit that affordability and insurance access are not clinical need.
What a final determination would and would not do: it would settle whether the three can be added to the 503B Bulks List, which none of them has ever been on. It would not reach 503A pharmacies, which never relied on that list, and it would not change anything about the branded options above.

Frequently asked questions
Did the FDA ban compounded GLP-1s in 2026?
No, and the framing is wrong in two ways. The May 1, 2026 action is a notice, not a rule, and it proposes not to INCLUDE semaglutide, tirzepatide and liraglutide on the 503B Bulks List. None of the three was ever on that list, so nothing was removed or excluded. Mass-market compounded GLP-1 actually ended in 2025, when FDA resolved the shortages and the enforcement-discretion windows closed — the last one on May 22, 2025. As of September 25, 2026, FDA has not published a final determination on the proposal.
Can a 503A pharmacy still compound semaglutide or tirzepatide?
Only in narrow, patient-specific circumstances. 503A pharmacies never relied on the 503B Bulks List, so FDA's 503B proposal has no direct effect on them. What ended routine 503A compounding was the 2025 shortage resolution, which switched off the 'essentially a copy' exception. What remains requires a prescriber-documented clinical need for a specific patient — for example a documented allergy to an inactive ingredient, or a strength that is not commercially manufactured. FDA has been explicit that cost and insurance access do not constitute clinical need.
Is the FDA comment period still open?
No. Comments on docket FDA-2018-N-3240 closed at 11:59 p.m. Eastern on July 30, 2026, after a thirty-day extension from June 30 (91 FR 38719, published June 26, 2026). The regulations.gov record shows the notice closed for comment and not withdrawn, with 4,277 comments posted to it. FDA has said it will publish its final determination in the Federal Register; as of September 25, 2026 it had not, and the newest FDA document in the docket was still the June 26 extension.
What happens if I just stop taking a GLP-1?
The trial evidence is consistent. In the STEP 1 extension, participants who had lost a mean 17.3% of body weight on semaglutide regained about two-thirds of it within one year of withdrawal, ending 5.6% below baseline, and most cardiometabolic improvements drifted back toward baseline. In SURMOUNT-4, participants switched from tirzepatide to placebo regained roughly 14%. Stopping is a legitimate choice, but it is one to plan with a prescriber rather than to arrive at by running out.
Is the advertised $449 Zepbound self-pay price what I will actually pay?
Only if you refill on schedule. Lilly's Self Pay Journey Program terms condition the $449 price for 7.5–15 mg on completing each refill purchase within 45 days of the previous delivery. Outside that window the regular price applies, which as of September 25, 2026 is $499 at 7.5 mg and $699 at 10, 12.5 and 15 mg, for the vial and the KwikPen alike: $250 a month more at the higher doses. A supply gap during a transition is exactly the circumstance that triggers it.
