ARK never bills treatment and takes no share of what a clinic charges you — you pay the clinic or vendor directly. Prices shown are their own published prices, labelled with how they were verified.
What they do
Expanded Wharton's-jelly MSC protocols across spine, orthopaedic, neurological, autoimmune and anti-ageing indications.
The evidence behind the primary service
MSC stem cells (systemic / IV) — grade D, carried unchanged from the ARK Protocol Library. A clinic's score cannot exceed 20 of 100 on service evidence, so no clinic can rank well on an unproven therapy.
There is no positive randomised efficacy trial for systemic MSC infusion in the wellness indications it is sold for. The FTC has permanently banned operators for claiming less than the industry routinely claims.
The systemic-infusion evidence base is one 30-person safety trial in frail 75-year-olds from 2017, with a non-monotonic dose response, never replicated.
