GLP-1 Pill vs Injection: The Full Comparison (Not GLP-1 vs GLP-2)

GLP-1 pill or injection: which should you pick?

Neither is better for everyone. Pick by what matters most to you.

• Biggest average weight loss: a tirzepatide shot, such as Zepbound.
• No needles, FDA-approved: the Wegovy pill, if you can keep a strict morning routine.
• No needles and no routine: Foundayo, the other FDA-approved weight-loss pill. Its average effect in trials was smaller than the shots.
• Lowest brand-name price: the Wegovy pill or Foundayo, bought straight from the maker. Both run about $150 to $300 a month by dose. The Wegovy pen costs about $350.
• Lowest price as the dose rises: a compounded semaglutide pill from Mochi Health, about $140 to $170 a month. Compounded means mixed by a pharmacy, not FDA-approved.
• On Medicare: the Medicare GLP-1 Bridge charges $50 a month for the Wegovy pill or pen, Foundayo or the Zepbound KwikPen. You need Part D, Medicare's drug coverage, and must meet its health rules.
• With private insurance: ask whether your plan covers Wegovy or Zepbound. Ro's membership includes help with prior authorization, the approval step many insurers require.
• Already juggling injections: a pill can mean one less needle in your week.

If you searched "GLP-1 vs GLP-2," that is a different question. GLP-2 is not another form of the same drug. The section near the end of this page explains.

Which costs less, the GLP-1 pill or the shot?

Brand versus compounded matters more than pill versus shot. At the makers' own prices, the Wegovy pill costs less than the Wegovy pen. A telehealth membership on top can flip that. Some compounded options cost less than both, but several cost more than the Wegovy pill's first doses.

Here is each option in the table.

Ro: both approved pills, with a prescriber

Ro offers both FDA-approved weight-loss pills, the Wegovy pill and Foundayo. It prescribes only FDA-approved medicines. The medicine costs the same as at the makers' own pharmacies.

• Wegovy pill: about $150 a month at the 1.5 mg starting dose, about $200 at 4 mg, and about $300 from 9 mg.
• Foundayo: about $150 a month to start, rising to about $300. Two early doses cost less for sign-ups by December 31, 2026. The top doses cost about $350 if a refill comes more than 45 days after the last one.

On top comes Ro's membership, about $150 a month. The first month costs about $40. Paying a year upfront brings it to about $75 a month. It covers visits, coaching and insurance help. A metabolic blood test is included when your provider orders one. All in, expect about $225 to $450 a month. More in our Ro review.

Hers and Hims sell the same two pills, starting at the same prices. Their membership is also about $150 a month, after a first month of about $40.

NovoCare: the Wegovy pill and pen from the maker

NovoCare is Novo Nordisk's own pharmacy service. It sells the Wegovy pill for about $150 to $300 a month by dose, with no membership. The Wegovy pen costs about $350 a month. The 7.2 mg HD pen costs about $400. New patients pay about $200 for each of their first two pen fills, through December 31, 2026.

NovoCare doesn't include a doctor, so you need your own prescription first. Novo's savings offer also gives these prices at many local pharmacies.

LillyDirect: Foundayo and the Zepbound shot

LillyDirect is Lilly's own pharmacy service. Here too, you need your own prescription.

Foundayo costs about $150 to $300 a month by dose, with no membership. The top doses keep that price only if each refill comes within 45 days.

Zepbound comes as a KwikPen or in vials. It starts at about $300 a month and rises to about $400 at 5 mg. From 7.5 mg, it is about $450 if each refill comes within 45 days. A late refill costs about $500 at 7.5 mg and about $700 from 10 mg.

Mochi Health: the cheapest compounded pill

Mochi Health sells a weekly compounded semaglutide pill. It costs about $140 to $170 a month, membership included. Prepaying a year of membership brings it to about $110 to $140. New members get the first month of membership free, though not in every state.

The pill is not FDA-approved. It has not been studied the way the Wegovy pill was. Mochi works as a marketplace of pharmacies, so the price can vary. Our Mochi Health review covers its pharmacies.

Henry Meds: compounded tablets, including tirzepatide

Henry Meds sells compounded semaglutide tablets for about $250 a month. Paying a year upfront brings them to about $150 a month. Its tirzepatide tablets cost about $350 a month, billed every three months. No tirzepatide pill is FDA-approved.

Visits and shipping are included, with no membership. At Henry, the tablets cost less than its semaglutide shot. See our Henry Meds review.

LevelsRx: semaglutide drops

LevelsRx sells compounded semaglutide as a daily liquid, taken with a dropper. It starts at about $270 a month, a little more than its shot. Unlimited video visits and nutrition coaching are included. The exact plans only appear once you start the intake. The brand is new and has few public reviews.

Fridays: a compounded semaglutide shot

Fridays sells compounded semaglutide shots. They cost about $150 a month with a year paid upfront. Month to month, they cost about $280. Fridays also sells a daily oral semaglutide blend, but only as a wellness microdose, not for weight loss. See our Fridays review.

JoinSkinny also offers an oral compounded GLP-1. Its price appears only after the intake.

Does the GLP-1 pill work as well as the shot?

It depends on which pill. The Wegovy pill comes close to the semaglutide shot. The Ozempic pill is a type 2 diabetes tablet that replaced Rybelsus in May 2026. Rybelsus did much less for weight in its trials.

• Wegovy pill, 25 mg: in the OASIS 4 trial, people lost 13.6% of their weight on average at 64 weeks, against 2.2% on placebo.
• Wegovy shot, 2.4 mg: in STEP 1, people lost 14.9% at 68 weeks, against 2.4% on placebo.
• Zepbound shot, 15 mg: in SURMOUNT-1, people lost 20.9% at 72 weeks, against 3.1% on placebo.
• Rybelsus 14 mg, the older diabetes tablet: in PIONEER 1, people with type 2 diabetes lost about 2.3 kg, roughly 5 pounds, more than placebo over 26 weeks.

So the ranking, from strongest to most modest: the tirzepatide shot, then the semaglutide shot and the Wegovy pill close together, then the older diabetes tablet. These trials were run separately, so treat the gaps as a rough guide. Trial averages describe a group, not a promise for you.

What's actually different between the pill and the shot?

The shot is simple. You inject semaglutide or tirzepatide under the skin once a week. It absorbs slowly over several days.

A semaglutide pill has a harder job. Stomach acid normally breaks down drugs like semaglutide before they can be absorbed. The Wegovy pill and the Ozempic pill solve this with an added ingredient, SNAC. It helps a small part of the dose get through the stomach wall.

That comes with strict rules. You take it first thing in the morning, on an empty stomach, with no more than 4 ounces of water. Then you wait at least 30 minutes before any food, drink or other pills. Skip a step and less of the dose gets in. Our Wegovy pill dosage guide walks through the routine.

Foundayo works differently. It is orforglipron, a GLP-1 pill that is not a peptide. The FDA approved it on April 1, 2026. You can take it at any time of day, with or without food. The shot has no timing rules either. Full price paths are in Foundayo cost. The step-up chart is in the Foundayo dosage guide.

Side effects: is one easier on your system?

Pills and shots cause the same kinds of side effects, because the medicine acts on the same hormone once it is in your body. Nausea, vomiting, diarrhea and constipation are the most common. They are usually worst in the weeks after a dose increase, then ease.

The pill is not gentler by default. In OASIS 4, 74% of people on the Wegovy pill had a stomach side effect, against 42% on placebo.

Taking a semaglutide pill the wrong way does not usually cause a new side effect. It lowers how much of the dose gets in, so the result may be weaker.

One note if you still use birth control pills. Zepbound and Foundayo can make them less reliable. Their labels advise a non-pill method or a barrier method, such as condoms, for about a month after starting and after each dose increase.

No head-to-head trial shows one format is easier on the stomach. Your own tolerance matters more than the format. For the full picture, see our GLP-1 side effects guide.

Is GLP-1 the same as GLP-2?

No. Both are gut hormones with similar names. They do different jobs.

GLP-1 slows digestion and quiets appetite. It is how semaglutide and tirzepatide work. GLP-2 helps the gut lining grow and absorb food.

The only FDA-approved GLP-2 drug is teduglutide, sold as Gattex. It treats short bowel syndrome, a rare condition where the gut can no longer absorb enough food. GLP-2 has no role in weight loss. Our GLP-1 vs GLP-2 guide explains more.

Are "peptides" a real alternative to GLP-1?

Semaglutide and tirzepatide already are peptides, short chains of amino acids. That is why a semaglutide pill needs help to get through the stomach.

What people usually mean is "research peptides," such as BPC-157 or AOD-9604. They are sold online outside licensed pharmacies, often labeled "not for human consumption." None is FDA-approved for any use. Human safety data are thin.

In 2023, the FDA put BPC-157 on its list of compounding ingredients with significant safety risks. It came off that list in April 2026, after the groups that had nominated it withdrew. In July 2026, an FDA advisory panel voted 8 to 6 to allow it in compounding. The FDA has not made a final decision, so pharmacies still can't compound it.

These products are not a cheaper or gentler GLP-1. They are a different, largely unregulated risk. Our guide to the best peptides for menopause sorts which ones have real evidence.
