In 2026, the cheapest FDA-approved GLP-1 for most self-pay patients is the daily Foundayo pill at about $299 per month, followed by Zepbound 2.5 mg pens at $499. Ozempic, Wegovy and higher Zepbound doses run $675–$1,349 at list price, while compounded semaglutide or tirzepatide average $231–$330 for a month’s supply. Your real out-of-pocket cost depends on dose strength, insurance, discount cards and whether you switch molecules when dose-escalation makes your current option pricier.

Ozempic’s 2026 list price is $1,027.51 per four-dose pen, or roughly $257 per weekly 0.25–1 mg dose. (drugs.com)
Wegovy pens list at $1,349.02 per package, equal to about $140 per delivered milligram at the maintenance 2.4 mg weekly dose. (novocare.com)
Zepbound’s official price ranges from $499 for 2.5 mg to $699 for 15 mg per month when purchased through LillyDirect or retail pharmacies. (zepbound.lilly.com)
Foundayo (orforglipron) has a manufacturer-set self-pay price of $299 per 30-day bottle regardless of dose, making it the lowest cash price among branded GLP-1s. (lilly.gcs-web.com)
Median first-month cash prices advertised online for compounded semaglutide and tirzepatide are $231 and $330, respectively. (jamanetwork.com)

Bottom line: In 2026 you will pay the least per milligram with Foundayo or reputable compounded semaglutide, while Wegovy remains the most expensive unless insurance or a copay card reduces your share.

What GLP-1 Pricing Looks Like in 2026

GLP-1 pricing in 2026 is driven by molecule exclusivity, dose strength and competitive positioning rather than manufacturing cost. Novo Nordisk and Eli Lilly still set wholesale acquisition cost (WAC) for their injectable semaglutide and tirzepatide products, and each company now sells direct-to-consumer through NovoCare and LillyDirect alongside traditional pharmacy distribution.

Definition: Wholesale acquisition cost (WAC) is the manufacturer’s list price paid by wholesalers before any rebates or discounts are applied. Patients paying cash often face the full WAC unless they use a manufacturer copay card or a free Rx.com discount card to capture pharmacy-level savings.

Novo Nordisk confirmed in a February 24, 2026 press release that Wegovy and Ozempic list prices will not drop until January 1, 2027, keeping this year’s sticker prices near historic highs. (novonordisk.com)

How Branded Injections Compare on $/mg

At current list prices, Zepbound delivers the lowest cost per milligram among the weekly injections, while Wegovy is the highest due to its larger 2.4 mg maintenance dose.

Drug	Package strength (total mg)	List price 2026	Cost per mg
Ozempic 0.25–1 mg pen	4 mg	$1,027.51	$257
Wegovy 2.4 mg pen	9.6 mg (4 weekly doses)	$1,349.02	$141
Zepbound 5 mg pen carton	20 mg	$399*	$20
Zepbound 15 mg pen carton	60 mg	$699*	$12
Mounjaro 5 mg pen carton	20 mg	$1,112.16	$55

*Manufacturer promotional pricing through LillyDirect as of June 2026. (zepbound.lilly.com) Cost per mg rounds to the nearest whole dollar.

⚠️ Why cost per mg matters

Weekly GLP-1 injections escalate from microdoses to full therapeutic doses over several weeks. When you double the injection size, you double mg delivered, not pens used. Cost per mg lets you predict the true monthly bill after titration.

Why the Foundayo Pill Changes the Math

Foundayo’s flat $299 list price for a 30-day bottle means its per-mg cost drops as you move from the starter 3 mg daily dose to the maintenance 17.2 mg daily dose. Lilly set that price to undercut injectable competitors and capture cost-sensitive patients who dislike needles.

Foundayo dose	Daily mg	Total mg/month	$299 cost per mg
3 mg (start)	3	90	$3.32
7.5 mg	7.5	225	$1.33
14.5 mg	14.5	435	$0.69
17.2 mg (maintenance)	17.2	516	$0.58

Even at the tiny starter dose, Foundayo beats Wegovy on per-mg price. At maintenance, it delivers nearly 240 percent more drug for less than one-quarter the cost per milligram.

How Compounded Semaglutide & Tirzepatide Stack Up

Compounded GLP-1s remain the lowest cash path to these molecules, but quality varies and they are not FDA-approved. A 2024 JAMA Health Forum audit of 114 websites found median first-month prices of $231 for semaglutide and $330 for tirzepatide. (jamanetwork.com)

The same study reported a wide interquartile range (IQR $189-$294 for semaglutide; $275-$399 for tirzepatide), illustrating how membership fees, vial size and bundled telehealth influence the headline number.

Is compounded GLP-1 right for my budget?

Check the column that fits your situation:

✅ Good to consider

No coverage for branded GLP-1s and paying full cash price
Comfortable self-injecting from a vial with insulin syringes
Able to verify pharmacy is 503A or 503B with current certificates
Okay with off-label use and informed of regulatory status

🏥 See a doctor first

History of thyroid C-cell tumors or pancreatitis
Need Medicare or commercial insurance reimbursement
Unsure how to calculate microgram doses from a multi-dose vial
No reliable cold-chain shipping option in your area

Break-Even Points for Switching Drugs or Doses

The cheapest GLP-1 today may not stay cheapest once you advance your dose. Below are common break-even scenarios:

Starter strategy (Weeks 0–8): Patients titrating Ozempic from 0.25 mg to 1 mg often stay within a single pen for eight weeks. Per-mg cost exceeds Zepbound 5 mg after week 4, so switching to Zepbound before escalation can save about $200 over the first two months.

Maintenance strategy (Week 9+): At 2 mg Ozempic or 15 mg Zepbound, Foundayo’s flat $299 beats both injections even after adding the cost of alcohol swabs and sharps disposal.

Scenario	Monthly dose delivered	Cheapest option	Savings vs next best
Early titration (1 mg/week)	4 mg	Zepbound 5 mg carton	$628
Mid titration (1.7 mg/week)	6.8 mg	Foundayo pill	$450
Full maintenance (2.4 mg/week)	9.6 mg	Foundayo pill	$1,050
Insurance denial	Any	Compounded semaglutide	$700–$1,100

Savings calculated against Wegovy list price and rounded to the nearest dollar.

Insurance, Coupons and 2026 Medicare Updates

Medicare: The GLP-1 Bridge program lets eligible Medicare Part D members fill Wegovy or Zepbound for $50 per month from July 1 through December 31, 2026. (wegovy.com)

Commercial insurance: All three major pharmacy benefit managers (CVS Caremark, Express Scripts and OptumRx) added Foundayo and Zepbound to standard formularies in May 2026. (investor.lilly.com)

Manufacturer copay cards: Ozempic, Wegovy and Zepbound each offer $25 copay for eligible commercially insured patients, though supply limits and prior authorization apply.

Cash-pay tip: Always run the prescription through the Rx.com price-comparison tool before you leave the doctor’s office. Most patients pay 55-85 percent less on generics and can still apply those savings to supplies like syringes and alcohol pads.

🚨 When to Contact Your Healthcare Provider

Contact your doctor immediately if you experience any of the following:

Severe stomach pain that will not go away - may signal pancreatitis, a known but rare GLP-1 risk
Persistent nausea and vomiting - can lead to dehydration and electrolyte imbalance
Difficulty swallowing or neck swelling - possible thyroid C-cell tumor symptom
Sudden vision changes - may indicate diabetic retinopathy complications
Signs of gallbladder disease such as fever or yellowing skin
Thoughts of self-harm or depression - mood changes have been reported with rapid weight loss; call or text the 988 Suicide & Crisis Lifeline anytime
Severe allergic reaction - swelling of face or throat, trouble breathing, or rash
Rapid heartbeat with dizziness - could reflect severe dehydration or electrolyte shift

Frequently Asked Questions

Is Foundayo the generic version of Wegovy?

No. Foundayo contains orforglipron, a different GLP-1 receptor agonist than semaglutide in Wegovy. The pills are FDA-approved under their own patent, so they are not generics and are not interchangeable.

Will Ozempic and Wegovy really drop to $675 in 2027?

Yes, Novo Nordisk announced that it will cut the list price of both drugs roughly in half on January 1, 2027. Your copay may still depend on your plan’s formulary design. (novonordisk.com)

How does cost per mg translate to weight-loss results?

Cost per mg helps you compare drugs on an equal potency basis, but weight-loss outcomes depend on factors like adherence, titration schedule and lifestyle habits. Paying less per mg does not guarantee more weight loss if you cannot tolerate the dose.

Can I combine Foundayo with Ozempic to save money?

No clinical trials have tested dual semaglutide and orforglipron therapy, and combining GLP-1s could raise the risk of side effects without additive benefit. Stick with one GLP-1 unless your physician specifically directs otherwise.

Are compounded GLP-1s legal in every state?

Compounded drugs are legal when prepared by licensed 503A or 503B pharmacies in compliance with state boards of pharmacy and FDA regulations. Some states restrict office-use compounding or out-of-state shipping, so always verify your state’s rules.

Which GLP-1 is cheapest with insurance?

With commercial insurance, Zepbound and Foundayo often end up cheapest because both Lilly copay cards cap your monthly cost at $25 if prior authorization is approved. Your exact cost depends on your deductible and plan tier.

What supplies add hidden costs to injectable GLP-1s?

If your pen does not include needles (Ozempic and Wegovy do not), you will need pen needles that cost about $0.15 each, plus alcohol swabs and a sharps container. These add roughly $10–$15 per month to your total.
