Weight Loss Injections: Types, Costs, and How to Get Them Online (2026)

Eric GoldWritten by Eric GoldEditor-in-Chief
12 min readUpdated August 21, 2026

Weight loss injections are prescription GLP-1 medications you inject to reduce appetite and support weight loss: semaglutide (brand names Wegovy and Ozempic), tirzepatide (brand names Zepbound and Mounjaro), and liraglutide (brand name Saxenda). All three are available through licensed telehealth providers after an online health review. Price is where your choices diverge sharply: brand-name injections list at $900 to $1,349 a month without insurance, while telehealth programs built on compounded semaglutide (not FDA-approved; more on what that means below) start around $99 a month for the medication, prescriber review, and shipping combined. This guide walks through what each injection actually is, what the clinical trials measured, real 2026 pricing on both the brand and compounded routes, and how online prescribing works from your first intake form to your first shipment.

Step 1: Answer an Online Health Quiz Screening for GLP-1 Injection Risks

The intake form takes about 5 to 10 minutes: your current weight, height, weight loss goals, and health history, including any thyroid, pancreatic, or gallbladder conditions and every medication you take. That form is what a licensed provider uses to decide which injection, if any, is appropriate for you and at what starting dose.
  • Expect questions about BMI, blood pressure, and family history of thyroid cancer or pancreatitis
  • List every current medication and supplement so the provider can screen for interactions
  • Most quizzes are free to complete and take under 10 minutes

Step 2: A Licensed Provider Selects Your Injection and Starting Dose

A licensed US provider reviews your intake and decides whether a GLP-1 injection fits your health profile, then which one. This is also where the brand-versus-compounded decision happens: brand medications carry FDA approval and a higher price, while compounded versions cost less but are prepared by a pharmacy rather than manufactured and reviewed by the FDA as a finished product. Before you commit, your provider can also flag whether your insurance is likely to cover a brand option.
  • The provider confirms an injectable GLP-1 is appropriate given your history before prescribing anything
  • You choose between brand (FDA-approved, higher cost) and compounded (lower cost, not FDA-approved) with the provider's input
  • Ask about starting dose, titration schedule, and what counts as a side effect worth reporting

Step 3: Your Injection Ships in Cold-Chain Packaging With Self-Injection Instructions

Once approved, your medication ships in discreet, temperature-controlled packaging, typically within 24 to 48 hours. Injectable GLP-1s have to stay cold in transit, so providers use insulated boxes with ice packs. Inside, you'll find syringes or a pre-filled pen, alcohol wipes, and written dosing instructions.
  • Cold-chain shipping keeps the medication stable from pharmacy to your door
  • Your first box includes injection supplies and step-by-step dosing instructions
  • Refills are scheduled through your online account so you don't run out mid-titration

Step 4: Follow Your Provider-Set Dose Titration Schedule

GLP-1 injections start at a low dose and increase on a set schedule, usually every 4 weeks, so your body adjusts gradually and side effects stay manageable. Your provider maps out that schedule up front and stays reachable for check-ins as your dose changes. If side effects show up, report them instead of adjusting your dose on your own; off-schedule dose changes are a common cause of avoidable nausea and GI upset.
  • Dose increases typically happen every 4 weeks on a schedule your provider sets
  • Message your provider about side effects before changing your dose yourself
  • Regular check-ins track your progress and catch problems early

What Counts as a Weight Loss Injection?

Three GLP-1 (or GLP-1/GIP) molecules make up nearly every weight loss injection prescribed today: semaglutide, tirzepatide, and liraglutide. Semaglutide is sold as Ozempic (FDA-approved for type 2 diabetes, prescribed off-label for weight loss) and Wegovy (FDA-approved specifically for chronic weight management). Tirzepatide is sold as Mounjaro (diabetes-approved) and Zepbound (weight-management-approved); both are made by Eli Lilly and contain the identical molecule, dosed the same way. Liraglutide is the oldest of the three, sold as Victoza (diabetes) and Saxenda (weight management), and is injected daily rather than weekly.
Each of these is also available compounded: a licensed pharmacy prepares its own formulation containing the same active ingredient outside the brand manufacturer's supply chain, at a lower price. Compounded versions are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality. Compounded semaglutide and compounded tirzepatide are the two you'll see most often from telehealth weight loss programs; compounded liraglutide exists but is less common, since daily injections have lost ground to the once-weekly options.
  • Semaglutide: Ozempic, Wegovy, or compounded semaglutide (weekly injection)
  • Tirzepatide: Mounjaro, Zepbound, or compounded tirzepatide (weekly injection)
  • Liraglutide: Victoza, Saxenda, or compounded liraglutide (daily injection)

Weight Loss Injection Cost Comparison (2026)

Price is usually the deciding factor between weight loss injections, and the spread is large. Brand-name Wegovy lists at roughly $1,349 a month at retail, but Novo Nordisk's own self-pay channel, NovoCare Pharmacy, sells it for $349 a month for standard doses ($399 for the 7.2mg high dose, as of August 2026) with no insurance required. Brand Ozempic, prescribed off-label for weight loss, typically runs $900 to $1,300 a month without insurance. Brand Zepbound lists at $1,086 to $1,300 a month at retail pharmacies; Eli Lilly's LillyDirect self-pay vials cut that to $299 to $449 a month with an on-time refill (7.5mg and up require refilling within 45 days to hold $449, or the price reverts to $499-$699), roughly a 35 to 75 percent discount off the pen price depending on dose and refill timing. As of August 2026; confirm current pricing at checkout.
Compounded semaglutide contains semaglutide, the same active ingredient used in Wegovy and Ozempic; compounded versions are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality. Telehealth programs offering it in our comparison set start around $99 a month and range up to about $227 a month, all-inclusive of the prescriber visit and shipping. That undercuts even the NovoCare self-pay brand channel by roughly $120 to $300 a month.
Compounded tirzepatide follows the same active-ingredient logic (it is not FDA-approved and is not reviewed by the FDA for safety, effectiveness, or quality either), but its availability has narrowed. The FDA declared the tirzepatide shortage resolved in December 2024, which ended the legal basis for pharmacies to mass-produce copies of Mounjaro and Zepbound; what remains legal today is individualized compounding, where a prescriber documents a specific clinical reason (such as a modified dose) for a particular person rather than a standardized copy. If a site advertises cheap tirzepatide with no individualized review, that is a signal to look elsewhere, not a bargain.
  • Compounded semaglutide: about $99-$227/mo (telehealth programs, all-inclusive)
  • Wegovy self-pay (NovoCare): $349-$399/mo depending on dose, no insurance required (as of Aug 2026)
  • Wegovy retail list price: about $1,349/mo
  • Ozempic (off-label for weight loss): $900-$1,300/mo without insurance
  • Zepbound self-pay vials (LillyDirect): $299-$449/mo with on-time refill, up to $699/mo if a refill lapses (as of Aug 2026)
  • Zepbound retail list price: $1,086-$1,300/mo
  • Compounded tirzepatide: individualized-prescribing lane only since the Dec 2024 shortage resolution; treat broad advertised availability with caution

Semaglutide vs Tirzepatide vs Liraglutide: How the Injections Compare

In the STEP 1 trial, published in the New England Journal of Medicine in 2021, adults taking semaglutide 2.4mg lost an average of 14.9% of body weight over 68 weeks. In the SURMOUNT-1 trial, published in NEJM in 2022, adults taking tirzepatide at the 15mg dose lost an average of 20.9% of body weight over 72 weeks, with 91% of participants losing at least 5% of their body weight. A head-to-head trial (SURMOUNT-5) comparing the two directly found tirzepatide averaged 20.2% weight loss versus 13.7% for semaglutide at 72 weeks. Liraglutide, the older of the three, produced smaller average results in its SCALE trial: participants lost an average of 8.4 kg (about 8% of the trial's average starting weight) over 56 weeks.
Those are trial averages, not guarantees. Individual results vary widely around every one of these numbers: some people lose considerably more than the average, some lose less, and response depends on dose, adherence, diet, and individual biology. Tirzepatide's higher average has made it the more in-demand molecule, but semaglutide and liraglutide remain effective, FDA-approved options with a longer real-world track record.

Brand-Name vs Compounded Weight Loss Injections

Brand-name injections (Wegovy, Ozempic, Zepbound, Mounjaro, Saxenda, Victoza) are manufactured and reviewed by the FDA as finished products, dosed in pre-filled pens with locked, consistent doses. Compounded injections contain the same active ingredient prepared by a licensed compounding pharmacy instead of the original manufacturer; they are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality, which is why they cost less and why you draw your own dose from a vial with a syringe rather than clicking a pen.
The FDA has issued warning letters to telehealth companies over how they market compounded GLP-1 medications, largely for implying compounded products are equivalent to or interchangeable with the brand drug. They are not the same product, even when they share an active ingredient. Before choosing a compounded program, confirm it names a specific licensed US pharmacy, requires an individual provider review rather than a checkbox order form, and does not claim its product is "the same as" or FDA-approved. You can read the FDA's own explanation of compounding rules at FDA compounding.

Weight Loss Injection Side Effects and What to Expect

The most commonly reported side effects across semaglutide, tirzepatide, and liraglutide in clinical trials are gastrointestinal: nausea, diarrhea, constipation, and vomiting, especially during the first few weeks at each new dose. These usually ease as your body adjusts, which is why titration schedules increase the dose gradually instead of all at once. Less common but more serious risks reported in prescribing information include pancreatitis, gallbladder problems, and (in animal studies) thyroid C-cell tumors, which is why people with a personal or family history of medullary thyroid cancer or MEN 2 are not candidates for these medications.
Your provider reviews your health history specifically to screen for these risk factors before prescribing, and ongoing check-ins during titration are how side effects get caught and managed early rather than discovered after the fact. Weight regain after stopping a GLP-1 injection is well documented in trial extension data, so a realistic plan treats this as an ongoing treatment, not a short course, for as long as you and your provider agree it's working for you.

Where to Get Weight Loss Injections Online

Every legitimate path to a weight loss injection online runs through a licensed US provider, because these are prescription-only medications regardless of whether you choose brand or compounded. The providers shown above and below are pulled from our current comparison data for the weight-loss category, ranked by rating; what differs most between them is speed, price, and whether they offer both brand and compounded routes or just one. Look for three things: a named, specific pharmacy that fills your prescription, both brand and compounded options so you can compare pricing directly, and a licensed provider you can message with questions during titration rather than a one-time form.

Frequently Asked Questions

What are weight loss injections called?

The three GLP-1 weight loss injections are semaglutide (sold as Wegovy or Ozempic), tirzepatide (sold as Zepbound or Mounjaro), and liraglutide (sold as Saxenda or Victoza). All three are also available compounded, which contains the same active ingredient prepared by a licensed pharmacy instead of the brand manufacturer; compounded versions are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality.

How much do weight loss injections cost without insurance?

Without insurance, brand-name injections run $900 to $1,349 a month at list price, though self-pay manufacturer channels lower that: Wegovy through NovoCare Pharmacy is $349-$399/mo (as of August 2026) and Zepbound through LillyDirect vials is $299-$449/mo with an on-time refill, up to $699/mo if a refill lapses on the higher doses. Compounded semaglutide through telehealth programs starts around $99/mo and ranges to about $227/mo, all-inclusive of the provider visit and shipping (compounded medications are not FDA-approved).

Which weight loss injection works best, semaglutide or tirzepatide?

In trials, tirzepatide produced a higher average weight loss than semaglutide: 20.9% over 72 weeks in the SURMOUNT-1 trial versus 14.9% over 68 weeks in the STEP 1 trial for semaglutide, and a head-to-head trial found tirzepatide averaged 20.2% versus 13.7% for semaglutide at 72 weeks. Those are averages, not guarantees; individual results vary, and a licensed provider can help you weigh efficacy against cost and side-effect tolerance for your situation.

Are compounded weight loss injections legal and legit?

Getting a compounded weight loss injection through a licensed telehealth provider is legal when a licensed US provider reviews you individually and a licensed US pharmacy fills the prescription. What changed in 2024 and 2025 is scale: after the FDA declared the tirzepatide and semaglutide shortages resolved, pharmacies lost the legal basis to mass-produce standardized copies of the brand drugs, narrowing the lane to individualized prescriptions. Compounded medications are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality, so choose a provider that is transparent about its pharmacy and requires a real medical review.

How do you get weight loss injections online?

You complete a short online health quiz, a licensed US provider reviews your history and decides whether an injection is appropriate and which one, and if approved your medication ships in temperature-controlled packaging, typically within 24 to 48 hours. Your provider then sets a titration schedule and stays available for follow-up as your dose increases.

What are the side effects of weight loss injections?

The most common side effects reported in clinical trials for semaglutide, tirzepatide, and liraglutide are nausea, diarrhea, constipation, and vomiting, especially early in treatment and after each dose increase. Less common but more serious risks include pancreatitis and gallbladder problems, and these medications are not appropriate for people with a personal or family history of medullary thyroid cancer or MEN 2. Individual results and side-effect experience vary, which is why provider follow-up during titration matters.

How fast do weight loss injections work?

These medications start at a low dose and build gradually, and the trial averages (14.9% for semaglutide over 68 weeks in STEP 1, 20.9% for tirzepatide over 72 weeks in SURMOUNT-1) reflect over a year of titrated treatment, not a quick result. Individual pace varies with starting dose, titration schedule, and adherence, and providers generally treat this as an ongoing program rather than a short course.

Always consult with a qualified healthcare provider before starting any treatment. Individual results and experiences may vary. Read our full medical disclaimer.

Regulatory noticeRegulatory note (verified August 22, 2026): On February 20, 2026 the FDA issued MEDVi, LLC a warning letter (MARCS-CMS 721455) citing misbranding under sections 502(a) and 502(bb) of the FD&C Act. Reviewing medvi.io in December 2025, the FDA said labels bearing "MEDVi" implied MEDVi compounds the drugs when it does not, and that "Same active ingredient as Wegovy and Ozempic" and "Same active ingredient as Mounjaro and Zepbound" implied an FDA approval compounded drugs do not have. We found no close-out letter, so the matter appears open. MEDVi states medvi.io is affiliate-operated rather than company-operated; we could not verify that, and the letter is addressed to MEDVi, LLC. Read the FDA letter

Regulatory noticeRegulatory note (verified August 22, 2026): The FDA reviewed struthealth.com in December 2025 and, on February 20, 2026, issued Strut Health, LLC a warning letter, MARCS-CMS 721448. It raises two separate problems. Pictured product labels carry the "Strut" name, which the agency said represents Strut as the compounder of the semaglutide and tirzepatide products when it is not. Three site claims are also quoted, among them "Generic Zepbound, Mounjaro" and "Semaglutide is the active ingredient in the brand medications." Because compounded drugs hold no FDA approval, the FDA said wording of that kind implies one, and it cited misbranding under sections 502(a) and 502(bb) of the FD&C Act. FDA’s warning letter index shows no response letter and no close-out letter, so we treat the matter as open. Read the FDA letter

Verification limitationVerification note (checked August 23, 2026): we could not identify the legal entity behind HealthRx through public records. Its website does not name an operating company, its domain registration is privacy-shielded, and we could not confirm a listing in any business registry or accreditation database we checked. This is not a finding of wrongdoing. It means our usual checks, including our search of FDA enforcement records, could only be run against the brand name and domain rather than a confirmed company.

Regulatory noticeRegulatory note (verified August 22, 2026): Hers is a brand of Hims & Hers Health, Inc., and the FDA wrote to that company twice on September 9, 2025, once for each brand. The Hers letter, MARCS-CMS 716825, went to chief executive Andrew Dudum after an August 2025 review of forhers.com. It quotes two claims made for compounded semaglutide: "Weekly injectable GLP-1 with the same active ingredient as Ozempic and Wegovy" and "Clinically proven ingredients." The agency’s position is that compounded products carry no FDA approval, so claims like these imply a sameness with approved medicines that has not been established, making the products misbranded. FDA’s index lists neither a response nor a close-out letter, so the matter stands open. Read the FDA letter

Regulatory noticeRegulatory note (verified August 22, 2026): One sentence is all that FDA warning letter MARCS-CMS 715879 quotes. Sent to Sprout Health Partners LLC on September 9, 2025 after an August 2025 review of joinsprouthealth.com, it cites the line "GLP-1 medications are FDA-approved and backed by extensive clinical research..." Appearing on pages offering compounded semaglutide and tirzepatide, that statement implied to the agency that the compounded products themselves are FDA-approved, which they are not, and it was cited as misbranding under FD&C Act 502(a) and 502(bb). A search of FDA’s warning letter index turns up no close-out letter, so the matter appears open. Read the FDA letter

Regulatory noticeRegulatory note (verified August 22, 2026): Skinny.Rx operates as SkinnyRx, but the legal entity is Lean Rx, Inc., and that is the name on FDA warning letter MARCS-CMS 717989, dated February 20, 2026. Following a December 2025 review of skinnyrx.com, the agency objected to the "SkinnyRx" name on pictured labels, saying it implies SkinnyRx compounds the drugs itself, and to three marketing lines, including "Get access to the same active ingredient as name-brand GLP-1 medications" and "It contains the same active ingredient as FDA-approved medications." Compounded semaglutide and tirzepatide are not FDA-approved, so the FDA read those lines as implying an approval that does not exist and classed the products as misbranded. No close-out letter is posted; read the matter as unresolved. Read the FDA letter

Regulatory noticeRegulatory note (verified August 22, 2026): On September 9, 2025 the FDA sent Hims & Hers Health, Inc. a warning letter covering the Hims brand, MARCS-CMS 716567, drawn from a review of hims.com the previous month. Two lines about compounded semaglutide are quoted in it: "Same active ingredient as Ozempic and Wegovy" and "Clinically proven ingredients." Compounded drug products are not FDA-approved, and the agency said phrasing of this sort suggests otherwise, which is what makes the products misbranded under FD&C Act sections 502(a) and 502(bb). A companion letter went to the same company that day for its Hers brand. No close-out letter appears in FDA’s index; treat this as open. Read the FDA letter
