In 2026, GLP-1 medications come in three formats: weekly injectable, daily oral pill (with fasting requirements), and daily oral pill (no fasting). Each has distinct trade-offs in efficacy, convenience, and cost. Here's how they compare.
The Three Formats
| Format | Examples | Weight Loss | Self-Pay Cost | Key Trade-off |
|---|---|---|---|---|
| Weekly injectable | Wegovy, Zepbound, compounded sema/tirz | 15–21% | $99–$1,349/mo | Highest efficacy, requires injection |
| Daily oral (fasting) | Oral Wegovy (semaglutide 25mg) | ~15% | ~$1,350/mo | Same efficacy as injectable, strict fasting rules |
| Daily oral (no fasting) | Foundayo (orforglipron) | 11–12% | $149–$399/mo | Most convenient, lower efficacy |
Injectable: Still the Efficacy Gold Standard
Weekly injectable GLP-1s remain the most effective format for weight loss. Semaglutide 2.4mg (Wegovy) delivered approximately 15% body weight reduction in clinical trials. Tirzepatide (Zepbound), which targets both GLP-1 and GIP receptors, showed 20–21% weight loss at the highest dose.
Compounded versions of these injectable medications are available through telehealth providers at significantly lower prices — typically $99 to $279 per month depending on the provider and dose. The active ingredient is the same; the difference is that compounded medications are prepared by licensed compounding pharmacies rather than the original manufacturer, and they are not FDA-approved as finished products.

Oral Semaglutide: Same Drug, Pill Form
The FDA approved oral semaglutide 25mg for weight loss in early 2026. It delivers comparable efficacy to the injectable version — approximately 15% weight loss — but requires strict fasting protocols. You must take it on an empty stomach, with no more than 4 ounces of plain water, and wait at least 30 minutes before eating, drinking, or taking other medications.
For patients who wanted semaglutide's full efficacy without an injection, this was a breakthrough. But the fasting requirement creates real adherence challenges in daily life.
Foundayo: Maximum Convenience, Lower Efficacy
Foundayo (orforglipron) is the first oral GLP-1 with no food or water restrictions. Take it any time of day, with or without food. Clinical trials showed 11–12% weight loss over 72 weeks — meaningful, but lower than injectable alternatives.
At $149/month self-pay for the starting dose (potentially $25/month with commercial insurance), it's also the most accessible brand-name option for insured patients.
