Is Four Sigmatic legit?
Short answer: yes, Four Sigmatic is a real store, and our score is 3.4 out of 5. The main caveat: reports of subscriptions and charges without clear consent.
It sells mushroom coffee, creamers, elixirs and protein through its own website, us.foursigmatic.com. Independent reviews are still scarce, so judge it mainly on its policies. Returns: Contact Four Sigmatic before returning anything; items returned without contacting it first may not be refunded.
Our take: legitimate, but read the downsides below before you buy.
