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 score every provider against a published five-criterion rubric: BBB accreditation, certification, whether the price stays flat as the dose escalates, price transparency, and track record. A criterion we can’t verify scores zero, not the benefit of the doubt, and the full breakdown is printed on each review page, so you can make a confident decision instead of a hopeful guess.

These providers prescribe tirzepatide and semaglutide, which are FDA-approved. We may earn a commission, and it never changes your price.
