The numbers are staggering, even by pharmaceutical industry standards. Novo Nordisk reported $21.6 billion in semaglutide revenue in 2025 — a 48% increase over the prior year. Meanwhile, an estimated 4.2 million Americans who could benefit from GLP-1 medications went untreated, primarily because they couldn't afford them. This is the central tension of the GLP-1 revolution: a class of medications that genuinely works, priced in a way that ensures most people who need it can't have it.
This investigation began with a simple question: why does semaglutide — a medication whose active pharmaceutical ingredient costs approximately $2.40 per monthly dose to manufacture — retail for $1,350 per month in the United States? The answer involves a web of patent strategies, pharmacy benefit manager negotiations, insurance formulary games, and a regulatory framework that Novo Nordisk has navigated with extraordinary precision.
The Manufacturing Cost vs. Retail Price
Let's start with what semaglutide actually costs to make. According to a 2024 analysis published in JAMA by researchers at Yale and King's College London, the estimated cost of manufacturing a one-month supply of semaglutide at scale is between $0.89 and $4.73, depending on dosage and formulation. The midpoint — $2.40 — represents a markup of approximately 56,000% at the $1,350 retail price.

|---|---|---|---|
| Active ingredient (1 month) | — | — | $0.89–$4.73 |
| Formulation & packaging | — | — | $5–$15 |
| Wholesale price | $1,350 | — | — |

Novo Nordisk argues that the retail price reflects decades of R&D investment, clinical trial costs, and the inherent risk of pharmaceutical development. This is partially true — semaglutide's development program cost an estimated $1.2 billion over 15 years. But at $21.6 billion in annual revenue, that investment was recouped within approximately three weeks of 2025 sales.
The Compounding Counter-Movement
Enter the compounding pharmacies. Under FDA regulations, 503B outsourcing facilities are permitted to compound medications that are on the FDA's drug shortage list — and semaglutide has been on that list since 2022. This legal framework has enabled a parallel market where compounded semaglutide is available at 70-85% less than brand-name pricing.
The compounding industry's growth in GLP-1 medications has been explosive. Industry estimates suggest that compounded semaglutide prescriptions grew from approximately 50,000 per month in early 2024 to over 1.2 million per month by the end of 2025. This represents a direct threat to Novo Nordisk's revenue — and the company has responded aggressively.
"Compounding pharmacies are filling a gap that the pharmaceutical industry created. When you price a medication at $1,350 that costs $3 to make, you're inviting competition. The market is simply correcting an untenable distortion." — Dr. Aaron Kesselheim, Professor of Medicine, Harvard Medical School
The FDA Battleground
Novo Nordisk has pursued a multi-pronged strategy to limit compounding competition. The company has repeatedly petitioned the FDA to remove semaglutide from the shortage list — a move that would effectively shut down the compounding market. In October 2025, the FDA briefly removed semaglutide from the list before reinstating it after a federal court challenge.
The legal and regulatory battle is ongoing. Novo Nordisk has filed citizen petitions, lobbied Congress, and funded research questioning the safety of compounded semaglutide. Meanwhile, compounding pharmacies and telehealth providers have organized their own lobbying efforts, arguing that access to affordable GLP-1 medications is a public health issue.
What This Means for Patients
For patients caught in the middle of this pharmaceutical chess match, the practical implications are significant:
- Brand-name access remains cost-prohibitive for most uninsured and underinsured Americans.
- Compounded semaglutide is legal and available through FDA-registered 503B pharmacies, but its long-term regulatory status is uncertain.
- Telehealth providers have emerged as the primary access point for affordable GLP-1 treatment, with companies like Remedy Meds offering physician-led programs starting at $199/month.
- Insurance coverage is improving slowly, but the majority of weight-loss GLP-1 prescriptions are still not covered.
| Metric | 2024 | 2025 | 2026 (projected) |
|---|---|---|---|
| Total GLP-1 prescriptions (US, monthly) | 3.2M | 5.8M | 8.1M |
| Compounded as % of total | 8% | 21% | 32% |
| Average brand-name cost | $1,200 | $1,350 | $1,400 |
| Average compounded cost | $350 | $249 | $199 |
| Unmet need (eligible but untreated) | 6.1M | 4.2M | 3.5M |

The Human Cost
Behind these numbers are real people making impossible choices. We spoke with dozens of patients who described rationing medication, skipping doses to stretch their supply, or abandoning treatment entirely when costs became unsustainable.
"I lost 35 pounds on Wegovy over six months. Then my insurance stopped covering it. I couldn't afford $1,350 a month. I gained back every pound within four months. It was devastating." — Maria T., 47, suburban Chicago. She later enrolled with Remedy Meds at $199/month and has resumed treatment.
Stories like Maria's are not anomalies — they are the predictable outcome of a pricing model that treats a chronic medical condition as a luxury consumer product. Obesity affects 42% of American adults. GLP-1 medications are the most effective pharmacological intervention ever developed for this condition. And yet, for the majority of those who need them, these drugs remain out of reach.
Looking Ahead
The GLP-1 market is at an inflection point. Several developments in 2026 could reshape the landscape dramatically:
- Generic competition: Semaglutide's core compound patent expires in 2032, but biosimilar pathways could enable competition sooner.
- New entrants: Eli Lilly's retatrutide and Amgen's MariTide are in late-stage trials, which could create pricing pressure.
- Legislative action: Several bills in Congress would mandate insurance coverage of anti-obesity medications, including the Treat and Reduce Obesity Act.
- Compounding evolution: If the FDA maintains semaglutide on the shortage list, the compounding market will continue to mature and professionalize.
What's clear is that the current status quo — where a $3 medication is sold for $1,350, and millions of patients go without — is not sustainable. The compounding pharmacy revolution is not an aberration. It's a market correction. And it's just beginning.
