The honest guide to peptides for weight loss
We explain how GLP-1 medications like semaglutide and tirzepatide actually work, and independently compare the online providers that prescribe them — so you start with confidence, not confusion.
“Peptides for weight loss” almost always means GLP-1 medications — semaglutide and tirzepatide — prescribed and shipped through online telehealth providers. They work by curbing appetite and steadying blood sugar, under a clinician’s supervision.
The fastest way to start is to compare providers, not molecules. See our full ranked list of the best GLP-1 providers.
Weight-loss treatment got confusing fast
Two years ago, almost nobody had heard of GLP-1; now there are dozens of brands competing for your attention. Semaglutide, tirzepatide, “compounded” versions, peptides, patches — the names blur together, and every site claims to be the cheapest and the best.
That noise is exactly the problem. It’s hard to tell a legitimate, clinician-backed provider from a slick landing page. We test and compare programs on the things that actually matter — access, price, and support — so you can make a confident decision instead of a hopeful guess.
