Read this first
We are a competitor of the companies reviewed on this page. That is a conflict of interest and you should read everything here with it in mind. What we can offer against it: every factual claim is drawn from the company's own published material and linked, every clinical criticism applies equally to us where it applies, and no assessment on this page is for sale — the one company we carry advertising for, CoreAge Rx, is graded at our lowest tier in its own review, and those placements are labelled wherever they appear.
The benchmark nobody advertises, because there is no subscription attached to it. An FDA-approved molecule, from a regular pharmacy, usually for less than the compounded alternatives.
What the company states
- FDA status
- FDA-approved
- Active ingredient
- Single agent, standard dose
- Requires
- A prescription from any licensed prescriber
- Subscription
- None
Our assessment
Sildenafil and tadalafil have been generic for years. They are the exact molecules studied in the trials that made PDE5 inhibitors first-line therapy, manufactured to FDA-approved standards, and dispensed at doses a prescriber can titrate deliberately.
This matters as a reference point. Much of the direct-to-consumer market is selling compounded reformulations of these same two molecules at a monthly subscription price, and the marketing rarely mentions that the approved version exists and is frequently cheaper.
The catch is that it requires a prescriber, and the whole appeal of the online model is not having to talk to one. That is a real convenience, and it is also precisely where the clinical value sits.
Reasonable for
- Almost every man starting treatment for erectile dysfunction
- Men who want a dose their prescriber can adjust methodically
- Men who would rather not be on a recurring plan
Not for
- Men who have had a genuine maximum-dose trial without benefit — that finding points to second-line therapy, not a different tablet

If you want the other thing
A diagnosis, rather than a subscription.
If you have already been assessed and just need a refill, this may serve you well. If nobody has taken your blood pressure in years, that is the appointment to make.
