Comparing options

You know what they are. Which one?

There are only a few molecules — the rest is branding, dosing, and what your insurance will pay for. Below: every medication side by side, the five things worth comparing, and the head-to-heads written out in full.

Weight-loss figures are averages from each drug's pivotal trial and only appear where a weight-loss trial exists — the diabetes brands are shown as "—" rather than borrowing their molecule's number. List prices are cash prices before insurance, discounts, or savings cards, and they change often.

How to actually compare them

Five axes, in the order most people should weigh them.

Efficacy

Molecule beats brand here. Tirzepatide averaged the highest total body-weight loss in trials, semaglutide sits in the middle, and the older liraglutide and dulaglutide drugs are meaningfully behind. Compare trial averages, not the best result you saw on Reddit — and remember averages hide a wide spread in both directions.

Injection cadence

Most GLP-1s are a once-weekly injection. Saxenda and Victoza are daily, and Rybelsus is a daily pill with fussy timing rules (empty stomach, small sip of water, wait before eating). If you know you'll resent a daily routine, that alone rules options out.

What your insurance covers

This changes the math more than anything else on this list. Plans routinely cover a diabetes indication while excluding the same molecule prescribed for weight loss, and coverage rules shift year to year. Check your specific plan before you fall in love with a specific drug.

Brand vs compounded

Brand-name drugs are FDA-approved products with a published label and a manufacturer behind them. Compounded versions are mixed by a pharmacy, cost much less, and are not FDA-approved — the pharmacy, not the FDA, is your quality control. That tradeoff is a personal call, and it deserves a real look rather than a price comparison.

Side-effect profile

The class shares a gastrointestinal profile — nausea, constipation, diarrhea — concentrated in the weeks after each dose increase. Stronger drugs tend to bring stronger side effects, and how fast your titration schedule climbs matters as much as which drug you take.

Comparison reading

Comparing providers, not drugs

Which telehealth service you use decides your price and your medication menu as much as the prescription does.
