The verdict

1st Optimal takes it — 61.6/100 to 60.2/100, but only just.

1st Optimal grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. 1st Optimal is a Michigan-based telehealth and functional-medicine platform offering GLP-1 weight loss medications, including semaglutide and tirzepatide, as once-weekly injections or daily oral tablets. Defy Medical is close behind and may still be the better fit — see the factor split below.

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.
