1st Optimal vs Invyncible
The verdict
1st Optimal takes it — 61.6/100 to 61/100, 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. Invyncible is close behind and may still be the better fit — see the factor split below.
