Weight Loss Comparison
Choose Based on Your Priorities
No Needles
Foundayo is a daily pill — ideal if you're needle-phobic or prefer oral medication. No injection site rotation, no sharps disposal.
Proven Track Record
Wegovy has been FDA-approved since 2021 with extensive real-world data, cardiovascular outcome data (SELECT), and established insurance coverage.
Convenience
Foundayo: daily pill, any time, with food. Wegovy: weekly injection but only once per week. Choose based on your preference for daily vs weekly.
Cardiovascular Benefits
Wegovy's SELECT trial showed 20% MACE reduction in obesity + CVD. Foundayo does not yet have cardiovascular outcome data.
Storage & Travel
Foundayo stores at room temperature — easy for travel. Wegovy requires refrigeration until first use and has cold chain logistics.
Cost & Access
Wegovy is widely available but expensive (~$1,300-1,400/mo uninsured). Foundayo may be more affordable as a small molecule, but pricing TBD.
Which Should You Choose?
Foundayo (orforglipron) and Wegovy (semaglutide) are both GLP-1 receptor agonists, but they represent fundamentally different approaches to weight loss medication. Foundayo is a non-peptide oral pill taken daily without restrictions. Wegovy is a peptide-based weekly injection with FDA approval and extensive clinical evidence.
If you prioritize convenience and hate needles, Foundayo offers a major lifestyle advantage — a pill you take with breakfast (or any time). If you prioritize proven long-term data, cardiovascular risk reduction, and insurance coverage, Wegovy has a multi-year head start with the FDA approval and SELECT cardiovascular trial data.
For many patients, the choice may come down to timing. Wegovy is available now. Foundayo is pending FDA approval. If you're starting GLP-1 therapy today, Wegovy is the established option. If you can wait, Foundayo's oral convenience could be worth it.
Whichever you choose, track your protocol in Shotlee to build clean data for dose optimization and outcomes comparison.
Important Context for This Comparison
This comparison uses data from separate clinical trials (ATTAIN for Foundayo, STEP for Wegovy). Cross-trial comparisons are informative but imperfect — differences in patient populations, trial design, follow-up duration, and endpoint definitions mean numbers from separate trials are not directly interchangeable.
A direct head-to-head trial between Foundayo and Wegovy would provide the most definitive comparison. Until such data is available, this comparison provides useful context based on the best available evidence from each drug's respective trials.
Tracking your personal response data in Shotlee is particularly valuable when considering a switch. By documenting your outcomes on your current protocol — efficacy, side effects, adherence, and quality of life — you create an objective baseline for comparison if you transition to the alternative.
Foundayo vs Wegovy: Frequently Asked Questions
Neither is universally better. Foundayo offers oral convenience (daily pill, no fasting). Wegovy has FDA approval, proven cardiovascular benefits, and years of real-world data. Your choice depends on needle tolerance, insurance coverage, and personal preference.
Phase 2 data shows ~14.7% weight loss for Foundayo at 36 weeks, comparable to Wegovy's 14.9% at 68 weeks in STEP-1. Phase 3 ATTAIN-1 shows up to 27.3 lbs loss. Direct head-to-head trials would be needed for definitive comparison.
Switching should be done under medical supervision. Your prescriber can advise on transition protocols including timing and starting dose. Track both in Shotlee for comparison data.
No. Foundayo is an oral pill taken once daily. Wegovy is a subcutaneous injection given once weekly. This is the key differentiator for many patients.
Yes. Shotlee supports tracking any GLP-1 medication including Foundayo, Wegovy, Ozempic, Mounjaro, and more. You can compare your results across different protocols.
