Arc-1 vs OnlyRx
The verdict
OnlyRx takes it — 60.9/100 to 56.3/100.
OnlyRx grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. OnlyRx is a cash-pay GLP-1 telehealth platform offering compounded semaglutide and tirzepatide in both injection and oral disintegrating tablet (ODT) forms — an uncommon needle-free option.
We may earn a commission if you start care through some of these links, at no extra cost to you. It never moves the WeighScore, which is the weighted average of the six factors shown for every provider, and what we write about a provider is the same either way. See our disclosure.
