Legit is a loaded word. A better question is what you can verify before paying.
The page publishes tiered pricing, names its ingredients, avoids hormone or device claims, states results vary and includes an FDA disclaimer. It even lists nine green flags and five real gaps. Those are the habits of a page written to be read critically.
The green-flag tally is self-assessed on the brand's own site, so treat it as a claim, not an audit. Made in USA, Registered Facility and GMP-Certified are brand statements; facility registration is not FDA approval. The legal operating entity is unconfirmed, and similarly named products exist. Read the refund policy, confirm the exact domain and keep your order email.
