A polished website, telehealth questionnaire, or celebrity endorsement does not prove that an online prescription source is legitimate.
The most obvious red flag
A site offering prescription ED medicine without a valid prescription or meaningful clinical review is unsafe. So is a seller willing to ship controlled or prescription products from an unidentified source.
Use the current prescription label and clinician instructions as the controlling information. Online prices, formulas, and policies change, and a marketing page cannot account for an individual medical history. A responsible decision weighs evidence, contraindications, total cost, and the availability of follow-up care.
License and location
A legitimate service should identify the prescribing entity and dispensing pharmacy. Verify pharmacy licensing through the relevant state board and check whether the address and phone number are real.

Too-good-to-be-true claims
Guaranteed erections, no side effects, permanent cures, instant approval, and claims that a compounded product is FDA approved are warning signs.

Counterfeit and tainted products
FDA repeatedly warns about sexual-enhancement products containing hidden drug ingredients. Supplements sold as natural alternatives can be especially risky when they contain undeclared PDE5 inhibitors.
