Who each one suits
Good fit if you want sermorelin at a stated $199/month with no membership fee.
The catch: You can see what the first month costs, not what the second one does, until you have handed over your medical history. The $99 injection price is a first-month offer ("While Supplies Last"); the $249 or $299 a month that follows on its month-to-month plan appears only at checkout, after the intake.
Good fit if you want a needle-free option — Willow sells both semaglutide and tirzepatide as daily under-the-tongue tablets.
The catch: The price on each product page is the lowest dose's price. Tirzepatide shows "$399/mo" with no "from" and no dose note, and the FAQ says only that costs "vary by dosage." Willow's own help-center price list fills it in: $399 through 6.375 mg, then $499, $524 and $549 at the higher doses — up to $150 a month more than the figure on the page. Semaglutide's $299 becomes $399 at 7 mg. The prices are published, but a reader has to leave the product page to find them.
Where each one will treat you
SkinnyRx
Not published. The intake's shipping form accepts any of the 50 states plus DC, but a Louisiana address reaches a results page reading "No products available in your state"; a Colorado address gets the full menu. No other exclusion is published.
Willow
Two lists that differ by one state. Willow's FAQ lists 36: Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, Washington, Wisconsin and Wyoming. Its help center gives the same list without Wyoming and adds Puerto Rico. If you live in Wyoming, confirm before you pay.
