Arc-1 vs Emerge Weight Loss
The verdict
Arc-1 takes it — 56.3/100 to 55.1/100, but only just.
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. Emerge Weight Loss is close behind and may still be the better fit — see the factor split below.
