Arc-1 vs Shape Vantage
The verdict
Arc-1 takes it — 56.3/100 to 43/100.
Arc-1 grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. Arc-1 offers compounded semaglutide (from $249.99) and compounded tirzepatide (from $299.99) as per-dose purchases, not monthly subscriptions.
