LillyDirect Foundayo vs PlexusDx
The verdict
PlexusDx takes it — 67.7/100 to 67.2/100, but only just.
PlexusDx grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. PlexusDx (plexusdx.com) is a US GLP-1 telehealth platform offering compounded weight-loss medications with licensed providers in all 50 states. LillyDirect Foundayo is close behind and may still be the better fit — see the factor split below.
