Ark Health vs Onyx Weight Loss
The verdict
Onyx Weight Loss takes it — 58.8/100 to 56.8/100, but only just.
Onyx Weight Loss grades higher on WeighScore, our editorial score across cost value, dose & formulation, clinical oversight, labs & monitoring, fulfillment and contract terms. Onyx Weight Loss is a nurse-practitioner-led telehealth clinic based in Mooresville, NC, offering GLP-1 and GLP-1/GIP weight-loss medications alongside peptides and HRT across 8 states. Ark Health is close behind and may still be the better fit — see the factor split below.
