GLP-1 quick answers
Straight answers to the questions people ask most about GLP-1 medications — cost, which drug works best, eligibility, safety and coverage. Each answer leads with the bottom line, then the context.
Cost
What is the cheapest GLP-1 program in 2026?
The cheapest verified GLP-1 program is Embody, with compounded semaglutide from a flat $69/month and compounded tirzepatide from $119/month. Compounded telehealth is the lowest-cost route overall — branded GLP-1 at the pharmacy lists near $1,000–$1,350/month without insurance.
See the cheapest GLP-1 rankingHow much does GLP-1 cost without insurance?
Without insurance, branded GLP-1 (Wegovy, Zepbound) costs roughly $1,000–$1,350/month, while compounded semaglutide or tirzepatide through telehealth runs about $69–$300/month. Compounded is the same active molecule prepared by a compounding pharmacy, which is why it costs far less.
Estimate your costWhy is compounded GLP-1 so much cheaper than branded?
Compounded GLP-1 is cheaper because it's prepared by a compounding pharmacy rather than sold as a branded, FDA-approved finished product — it skips the branded drug's pricing. The trade-off is that compounded products aren't individually FDA-reviewed, so using a licensed, accredited pharmacy matters.
Compounded vs brandedWhich medication
Which GLP-1 medication is most effective for weight loss?
Tirzepatide (Zepbound) produces the most average weight loss of the FDA-approved options — about 15–21% of body weight in trials — edging semaglutide (Wegovy) at about 15%. A head-to-head trial, SURMOUNT-5, confirmed tirzepatide's average advantage. The investigational drug retatrutide showed even more (~24%) in early trials but is not approved.
Semaglutide vs tirzepatideAre Ozempic and Wegovy the same thing?
Ozempic and Wegovy are the same active molecule — semaglutide — from the same manufacturer. They differ in approved use and dose: Wegovy is approved for weight management (up to 2.4 mg weekly), while Ozempic is approved for type 2 diabetes (up to 2.0 mg weekly).
Ozempic vs WegovyWhat's the difference between Zepbound and Wegovy?
Zepbound is tirzepatide (a dual GIP/GLP-1 agonist) and Wegovy is semaglutide (a GLP-1 agonist). Both are FDA-approved for weight loss; Zepbound produces more average weight loss, while Wegovy has stronger cardiovascular-outcome evidence.
Zepbound vs WegovyWhat is compounded GLP-1?
Compounded GLP-1 is semaglutide or tirzepatide prepared by a compounding pharmacy rather than manufactured as a branded, FDA-approved finished drug. It's the same active molecule, sold through telehealth for far less, and is legal in specific circumstances — but it isn't individually FDA-reviewed for safety, effectiveness or quality.
Compounded GLP-1 guideResults & effectiveness
How much weight can you lose on GLP-1 medications?
In clinical trials, people lost an average of about 15% of body weight on semaglutide (STEP 1) and up to about 21% on tirzepatide (SURMOUNT-1) over roughly 15–17 months, alongside diet and activity changes. Individual results vary with dose, consistency and starting weight.
Results timelineHow fast does GLP-1 start working?
Appetite changes often begin within the first week or two, but meaningful weight loss builds over months as the dose is increased. In trials, most weight loss accrued over the first six to nine months.
Month-by-month timelineWhat happens if you stop taking GLP-1?
Most people regain a large share of lost weight within a year of stopping, because the medication treats the underlying appetite biology, which returns when you stop. GLP-1 therapy is generally treated as long-term rather than a short course.
Maintenance and stoppingEligibility & safety
Do I qualify for GLP-1 weight-loss medication?
You generally qualify if your BMI is 30 or higher, or 27 or higher with a weight-related condition such as type 2 diabetes, high blood pressure, high cholesterol or sleep apnea. A licensed clinician makes the final decision.
Check your eligibilityWhat are the side effects of GLP-1 medications?
The most common side effects are gastrointestinal — nausea, constipation, diarrhea and vomiting — usually worst during dose increases and improving over time. Serious but uncommon risks include pancreatitis and gallbladder problems, and the class carries a boxed warning for thyroid C-cell tumors.
Side effects & how to manage themIs compounded GLP-1 safe?
The active molecule is the same as the branded drug, so the medical risks are the same class of risks. The added variable is quality control: use a state-licensed, ideally LegitScript-certified pharmacy with a real prescriber, and avoid anything sold as a 'research chemical' or without a prescription. The FDA has warned about unapproved and improperly compounded GLP-1 products.
Run a provider safety checkWho should not take GLP-1 medications?
GLP-1 medications should be avoided by anyone with a personal or family history of medullary thyroid carcinoma or MEN 2, and used with caution in people with a history of pancreatitis. They are not recommended during pregnancy. Always review your history with a clinician.

How do I get GLP-1 medication online?
You get GLP-1 online by completing a medical intake with a licensed telehealth program; a clinician reviews it and, if appropriate, prescribes the medication, which a pharmacy ships to you. Legitimate programs require a real prescriber and use a licensed pharmacy — verify credentials before paying.
How to get GLP-1 safelyCan I get GLP-1 as a pill instead of an injection?
Yes, oral GLP-1 options exist — such as Rybelsus (oral semaglutide) — but the most effective GLP-1 treatments are still weekly injections. Most telehealth programs focus on injectable compounded semaglutide and tirzepatide.
Browse medicationsDoes insurance cover GLP-1 for weight loss?
Coverage is inconsistent: many plans cover GLP-1 drugs for type 2 diabetes but exclude them for weight loss, and prior authorization is common even when obesity is covered. Check your plan's formulary for the specific brand and indication.
Cost & insurance guideDoes Medicare cover GLP-1 for weight loss?
Standard Medicare Part D does not cover GLP-1 drugs for weight loss (a federal exclusion), but it covers them for type 2 diabetes and cardiovascular risk. A temporary Medicare GLP-1 Bridge program (July 2026–December 2027) offers Wegovy, Zepbound or Foundayo for a $50 copay to eligible members.
Medicare GLP-1 coverageDoes Medicaid cover GLP-1 for weight loss?
It depends on your state. Only about 11–13 state Medicaid programs cover GLP-1s specifically for obesity in 2026, and that list has been shrinking. GLP-1s for type 2 diabetes are covered much more widely. Check your state's current status.
