GLP-1 medications, made easier to compare

This page is built to help patients make sense of the major decision lines: which molecule, which brand, injection versus pill, FDA-approved versus non-approved, introductory dosing versus full maintenance dosing, how closely you want to be followed, and what kind of treatment relationship you actually want.

The goal is clarity, not hype. Some options are FDA-approved branded medications. Others are compounded or non-approved versions that may look similar on the surface but are not regulated the same way. Those are not interchangeable categories.

Quick navigation

Molecule choices

Start here. Most people first need to know the molecule name, the company behind it, the brand name, and whether it comes as an injection, a pill, or both.

FDA-approved brands shown
Semaglutide Novo Nordisk
FDA-approved
Weekly injection Daily oral tablet
Wegovy (weight management) • Ozempic (diabetes, cardiovascular risk) • Rybelsus / oral Wegovy (diabetes and weight pathways)
The semaglutide family spans obesity-focused and diabetes-focused products. Brand name matters because the indication and dose ladder differ even when the molecule is the same.
Tirzepatide Eli Lilly
FDA-approved
Weekly injection
Zepbound (weight management, obstructive sleep apnea with obesity) • Mounjaro (type 2 diabetes)
Tirzepatide acts on both GIP and GLP-1 pathways, making it dual-acting. Head-to-head data shows among the highest average weight loss of any approved agent. Often discussed alongside GLP-1s even though it is technically different.
Liraglutide Novo Nordisk
FDA-approved
Daily injection
Saxenda (weight management) • Victoza (type 2 diabetes)
An older but still relevant option. Requires daily injection rather than weekly, which creates a different adherence experience. Generally produces less weight loss than newer weekly agents in clinical comparisons.
Orforglipron Eli Lilly
FDA-approved
Daily oral tablet
Foundayo (chronic weight management in adults with obesity or overweight with at least one weight-related condition)
A newer oral GLP-1 that is its own molecule, not semaglutide. It offers a true pill-based path for weight management without any injection requirement.
Simple takeaway: brand names are not just marketing labels. They can signal a different indication, a different dose ladder, and a different regulatory pathway even when the active molecule overlaps.

Dose ranges, from introductory to full maintenance

Most GLP-1 treatment begins with a lower introductory dose and builds gradually as tolerated. Some low doses are official FDA-labeled starting doses. Very low custom “microdoses” marketed online are not part of any FDA-approved labeled regimen.

FDA-approved labeled dose step Often used as introductory titration Custom microdose or compound, not FDA-approved
Wegovy injection Semaglutide • Weekly injection FDA-approved
Introductory
0.25 mg weekly
Then 0.5 mg, 1 mg, 1.7 mg at 4-week steps
Maintenance
1.7 mg or 2.4 mg weekly

The low starting dose is an official ramp-up step, not a maintenance goal for most patients.

Wegovy tablets Semaglutide • Daily oral tablet FDA-approved
Introductory
1.5 mg daily
Then 4 mg, then 9 mg
Maintenance
25 mg daily

Oral semaglutide for weight management uses a distinct dose ladder and should not be assumed equivalent to injectable dosing.

Zepbound Tirzepatide • Weekly injection FDA-approved
Introductory
2.5 mg weekly
Maintenance
5 mg, 10 mg, or 15 mg weekly

The 2.5 mg dose is a starting dose, not a chronic maintenance dose for most weight-management use.

Mounjaro Tirzepatide • Weekly injection FDA-approved
Introductory
2.5 mg weekly
Maintenance
5 mg to 15 mg weekly

Same molecule family as Zepbound, but the brand and FDA indication differ (diabetes vs. weight management).

Ozempic injection Semaglutide • Weekly injection FDA-approved
Introductory
0.25 mg weekly
Maintenance
0.5 mg, 1 mg, or 2 mg weekly

Semaglutide for diabetes and cardiovascular risk reduction. Not the same labeled indication as Wegovy.

Rybelsus Semaglutide • Daily oral tablet FDA-approved
Introductory
3 mg daily
Maintenance
7 mg or 14 mg daily

Oral semaglutide for diabetes. Its dosing should not be borrowed for obesity care without regard to indication.

Saxenda Liraglutide • Daily injection FDA-approved
Introductory
0.6 mg daily
Increased by 0.6 mg weekly
Maintenance
3 mg daily

A daily pen rather than a weekly one. That may appeal to some patients and less so to others.

Foundayo Orforglipron • Daily oral tablet FDA-approved
Introductory
0.8 mg daily
Then 2.5 mg, then 5.5 mg
Maintenance
9 mg to 17.2 mg daily

A true oral GLP-1 for weight management. Its own molecule and dose ladder, distinct from semaglutide oral forms.

Custom “microdose” programs Molecule and form varies Not FDA-approved
Introductory
Below-labeled custom doses
Maintenance
Often individualized and non-standard

May be marketed as gentler or cheaper. Not automatically FDA-approved simply because they resemble a known molecule.

Important distinction: “microdosing” is a real word in the marketplace, but it is not itself an FDA-approved indication or standardized regulatory category. Beginning on a low, labeled starter dose of an FDA-approved product is very different from a custom compounded low-dose pathway sold outside the FDA approval system.

Oral versus injectable options

For some people, the biggest decision is not the molecule but the format. Pills may feel easier and more familiar. Injections may offer a different potency pathway or adherence experience.

Injectable options

Weekly or daily injections

Wegovy, Zepbound, Ozempic, Mounjaro, Saxenda, and Victoza are injectable products. Weekly injections can feel simpler for adherence, while daily injections allow a different rhythm but can feel more demanding over time.

Oral options

Tablet pathways now matter much more

Wegovy tablets, Rybelsus, Ozempic tablets, and Foundayo make pill-based treatment a real category rather than a fringe alternative. This matters for people who dislike needles, travel often, or want a simpler daily routine.

Best fit depends on goals

Convenience is not the only variable

The right choice also depends on indication, cost, insurance coverage, potency expectations, side-effect tolerance, and whether someone values faster escalation, slower titration, or easier day-to-day use.

FDA-approved products versus non-FDA-approved options

This is one of the most important sections on the page. Some products are FDA-approved branded medications with known labeled doses, established manufacturing oversight, and formal prescribing information. Others are not.

FDA-approved

Branded, labeled, regulated

These products have reviewed labeling, approved dose ladders, recognized indications, and standardized manufacturing expectations. That does not make them perfect or risk-free. It does mean the regulatory path is clear.

  • Known brand and manufacturer
  • Known FDA labeling and dose steps
  • Known approved indication
  • Pharmacy distribution through standard channels
Compounded or custom-mixed

Often cheaper, often less standardized

Compounded GLP-1 products are not FDA-approved. Some programs also combine the active chemistry with extra ingredients, fillers, vitamins, or alternate forms of the molecule. These may be marketed aggressively, but they are not the same as an FDA-approved product by brand.

  • Not reviewed by FDA as approved finished products
  • May differ in concentration, excipients, or formulation
  • May be presented under a telehealth brand rather than the actual compounder
  • May be used for custom microdosing pathways that are not on the FDA label
What patients often miss

“Looks similar” is not the same as “is the same”

A website can make a product appear equivalent to a branded GLP-1 even when the product source, approval status, concentration, and oversight are fundamentally different. That distinction matters when the goal is safe, sustainable, and transparent treatment.

Simple language version: if it is compounded, mixed, or custom-dosed outside the labeled branded pathway, it should be understood as non-FDA-approved unless clearly documented otherwise.

Sorting this out on your own is hard. It does not have to be.

A focused visit with Dr. Caplan can clarify which medication is appropriate, what is actually approved, and what a realistic plan looks like for your situation.

Ways to obtain GLP-1 medications

Not all access points are the same. The differences affect medication sourcing, safety, and how much guidance you receive along the way.

Direct manufacturer or pharmacy-based access

Prescriptions filled through standard pharmacies, sometimes with insurance or manufacturer-linked savings programs.

  • Medication sourcing: Usually FDA-approved branded medications
  • Follow-up: Ranges from minimal to moderate depending on the prescribing provider
  • Strength: Clear sourcing and standardized products
  • Tradeoff: Cost and coverage can be unpredictable without guidance

Low-touch telehealth platforms

Some platforms offer quick access and lower-friction onboarding, often using standardized protocols and streamlined follow-up.

  • Medication sourcing: May be FDA-approved or compounded depending on the program
  • Follow-up: Often protocol-driven with variable continuity
  • Strength: Convenience and speed
  • Tradeoff: Less individualized care and limited relationship depth
Relationship-based clinical care

Guided, personalized, physician-led

Ongoing care with a physician who helps guide medication selection, dosing, and long-term planning and stays with you through the full course of treatment.

  • Medication sourcing: Prescriptions filled through standard pharmacies
  • Follow-up: Personalized, adaptive, and higher-touch
  • Strength: Nuanced decision-making, continuity, and real clinical relationship
  • Tradeoff: Visit costs are higher than low-touch options

Compounding-focused programs

Some programs center on compounded GLP-1 products or customized dosing approaches that differ from standard FDA-approved pathways.

  • Medication sourcing: Often compounded and not FDA-approved
  • Follow-up: Ranges from minimal to structured
  • Strength: Lower upfront cost and flexibility in some cases
  • Tradeoff: Less standardization, more variability in sourcing and oversight

Monitoring and follow-up

Some people want a simple prescription. Others want real clinical follow-up, especially through the first few months when nausea, constipation, food aversion, fatigue, reflux, dose tolerance, and adherence questions are most likely to surface.

Lower-touch model

Minimal follow-up

This may work for experienced, uncomplicated patients, but it can leave significant value on the table, particularly in the early months.

  • Little real-time troubleshooting when symptoms arise
  • Dose increases may feel automatic rather than thoughtful
  • Less support for side effects, nutrition adaptation, or long-term sustainability
Higher-touch model

Guided early optimization

This is often where better outcomes are shaped, especially early on.

  • Closer check-ins during the first months of treatment
  • Attention to tolerance, appetite, intake, hydration, bowel habits, and practical daily fit
  • Intentional titration rather than reflexive escalation to the next labeled dose
  • More help aiming for durable results rather than short bursts of rapid progress

Early phase: first 1 to 3 months

Often benefits from more frequent contact. This is when people are learning how the medication feels, how quickly to escalate, and whether the current formulation is even the right fit.

Middle phase

Once someone is tolerating treatment, the focus often shifts to dose matching, pace of progress, nutrition quality, hydration, and avoiding overly aggressive titration simply because the next dose exists.

Maintenance phase

Later care may be lighter in frequency, but it still matters. Goals may evolve from initial weight loss to durability, comfort, metabolic improvement, or preventing rebound weight gain.

Duration of treatment

There is no one universally correct treatment length. The right time horizon depends on response, goals, tolerability, affordability, comorbidities, and personal preference.

Shorter-term use

Some people use treatment for a defined window of months to create momentum, improve metabolic markers, or bridge toward new habits and a different weight set point.

Longer-term maintenance

Others stay on therapy for years or indefinitely, particularly when the medication is functioning more like chronic disease management than a temporary boost. Most clinical evidence suggests weight returns when the medication is stopped.

Flexible or stop-start approaches

Some people move in and out of treatment depending on cost, side effects, life demands, preferences, or changing goals. That can be done thoughtfully, but it benefits significantly from physician guidance.

Bottom line: people do not all need the same molecule, the same dose, the same speed, the same format, or the same duration. Good care helps match the plan to the person and stays with them as that plan evolves.
