Analysis

Clinical trials show 14.9-20.7% body weight loss with semaglutide depending on dose. Standard Wegovy (2.4mg): 14.9-17% over 68 weeks. Wegovy HD (7.2mg, FDA-approved March 2026): 20.7% over 72 weeks. Month-by-month breakdown from the STEP trials.

Updated July 16, 2026: Oral Wegovy received European Commission approval July 15, 2026. EU milestone; Foundayo (orforglipron) remains US-only. CVS Caremark removed Foundayo's new-to-market block June 1 (~25-30M commercial lives can now be covered); Medicare GLP-1 Bridge covers both pills at $50/mo from July 1. Oral Wegovy produces 16.6% weight loss vs Foundayo's 12.4%; Foundayo starts at $149/mo self-pay with no fasting requirement.

Updated July 2026: Tirzepatide produces 20.2% weight loss vs semaglutide's 13.7% in the SURMOUNT-5 head-to-head trial (NEJM 2024): a 47% greater relative reduction confirmed by 2026 systematic meta-analyses. Tirzepatide activates GLP-1 + GIP dual receptors; semaglutide activates GLP-1 only. Full cost and side-effect comparison.

Updated July 10, 2026: Added biologic classification lawsuit context (Lilly v. FDA, Case 1:24-cv-01503). Obesity (TRIUMPH-1): 28.3% weight loss at 80 weeks, 30.3% at 104 weeks, 65.3% achieved BMI <30. T2D (TRANSCEND-T2D-1): A1C −2.0%, weight −16.8%. NDA expected Q4 2026. Court ruling: FDA's bright-line classification of retatrutide as a drug (not biologic) vacated. Outcome determines whether compounding can legally exist post-approval.

Updated July 2026: SURMOUNT-5 head-to-head trial (NEJM): Zepbound 20.2% vs Wegovy 13.7% weight loss at 72 weeks. Wegovy HD (7.2mg, FDA-approved March 2026) closes the gap at 20.7%. Wegovy self-pay (subscription): $249/mo (12-month) to $329/mo (3-month) via NovoCare, launched March 31: now cheaper than Zepbound's $299/mo starter vial for 12-month committers. Zepbound self-pay: $299-$449/mo (LillyDirect). Both $25/mo with commercial insurance + savings card.

How much do GLP-1 medications cost in 2026? Wegovy, Zepbound, Ozempic, Mounjaro & Foundayo range from $25 to $1,350/month. With insurance + savings card: $25/mo. Without insurance: $146/mo compounded sema (Yucca Health), $149/mo Foundayo pill, $299 to 449/mo brand injectable (LillyDirect, NovoCare). Medicare: $50/mo, live as of July 2026. Prices verified July 2026 across 48 providers.

Verified April 2026: Ozempic and Wegovy are both semaglutide from Novo Nordisk. Ozempic ($1,028/mo list) is approved for type 2 diabetes at max 2mg. Wegovy ($1,349/mo list) is approved for weight loss at max 2.4mg (or 7.2mg HD). Both drop to $349/mo self-pay via NovoCare.

Mounjaro (tirzepatide) and Ozempic (semaglutide) are both FDA-approved only for type 2 diabetes, neither is approved for weight loss (that's their sister brands, Zepbound and Wegovy). In the first head-to-head trial, SURMOUNT-5, tirzepatide beat semaglutide for weight loss (−20.2% vs −13.7% over 72 weeks), and in SURPASS-2 tirzepatide cut A1C more. But Ozempic's semaglutide has the SELECT cardiovascular outcome data Mounjaro doesn't. Here's the data-driven breakdown, plus the cheaper cash-pay paths if your insurance says no.

CagriSema (cagrilintide + semaglutide) lost 22.7% average body weight in adults with obesity (REDEFINE 1) and 13.7% in adults with type 2 diabetes (REDEFINE 2) over 68 weeks. Novo Nordisk filed its US application on December 18, 2025; an FDA decision is expected later in 2026 with no public PDUFA date. It is not FDA-approved and not legally available as of June 2026, here is the honest data, how it stacks up against drugs you can get today, and why every site selling 'CagriSema' right now is a red flag.

IvyRx offers compounded semaglutide from $175/month and tirzepatide from $275/month with a rare flat-rate model, your price never increases as your dose goes up. We reviewed their pricing, clinical oversight, and transparency. Key finding: the flat-rate pricing is genuinely valuable, but IvyRx doesn't publicly disclose a named medical director or their compounding pharmacy partners, which are meaningful gaps for patients who want to verify clinical quality.

Updated May 2026: 5 next-gen obesity drugs in Phase 3. Retatrutide (Lilly) 28.7% weight loss. CagriSema (Novo): REDEFINE-1 22.7% (obesity), REDEFINE-2 15.7% (T2D), PDUFA expected October 2026. MariTide (Amgen, monthly), survodutide, Foundayo approved April 2026. FDA approvals 2026-2028.

Verified April 2026: Zepbound and Mounjaro are the exact same drug (tirzepatide) at the same doses. Mounjaro was FDA-approved May 2022 for Type 2 diabetes. Zepbound was FDA-approved November 2023 for chronic weight management and December 2024 for obstructive sleep apnea. List price is ~$1,087/mo for both; with commercial insurance + savings cards both drop to $25/mo (max $1,950/yr). The real differences: which one your insurance covers, what the FDA label allows, and Zepbound's LillyDirect self-pay vials at $299-$449/mo, a program Mounjaro does not offer.

Verified April 2026: Brand-name Wegovy is $349/mo via NovoCare, Zepbound starts at $299/mo via LillyDirect. Compounded semaglutide is banned since Feb 2025; compounded tirzepatide remains legal at $149-299/mo under narrow medical-necessity rules. Full legal + safety comparison.

Verified April 2026: Oral Wegovy (25mg daily pill) produces 16.6% weight loss per the OASIS trial vs 14.9% for injectable Wegovy (2.4mg weekly) per STEP-1. Pill costs $1,349/mo list vs $349/mo self-pay for the injection through NovoCare. Full head-to-head comparison.

Verified April 2026: Tirzepatide costs $149/mo via Gala (compounded microdose), $299/mo via LillyDirect (brand Zepbound 2.5mg vial), $449/mo for LillyDirect 5mg+ vials, $25/mo with Zepbound savings card, or $1,086/mo retail list price. Full price breakdown with 47 verified providers.

Verified April 2026: Tirzepatide compounding enforcement began March 2025 after FDA removed it from the shortage list. Narrow medical-necessity exemptions still allow legal compounded tirzepatide at $149-300/mo (vs $1,086/mo retail Zepbound). Complete legal framework, safety, and verified pricing.

GLP-1 patches sold online don't contain semaglutide or tirzepatide, they're herbal supplements. Here's what the science says and what actually works.
