Sildenafil and tadalafil are both available as FDA-approved generics, which changes this category completely from the GLP-1 one. Generics are bioequivalence-tested and substitutable, and they are cheap — often under $2 a dose. Compounded 'custom' formulations cost more and carry none of that testing.
Why this category is not like GLP-1s
The central fact is that approved generics exist. Sildenafil and tadalafil both came off patent, multiple manufacturers make them, and a pharmacist can substitute one for another because each has demonstrated bioequivalence to the reference product.
That is precisely what compounded GLP-1s cannot do, and it collapses the affordability argument that drives the compounded market in weight management. Here, the approved product is the cheap option.
What the market actually charges
Telehealth platforms in this category typically bundle a consultation, the medication and shipping into a monthly or per-dose price. The medication component is generic and inexpensive; the price you pay is largely a service and convenience charge.
That is a legitimate business model. It becomes a problem when the pricing is presented as though the medication is the cost, or when a compounded “proprietary” formulation is priced as though its novelty confers benefit.
Compounded ED formulations, examined
Several platforms market compounded combinations — sildenafil with tadalafil, dissolvable or troche formats, or additions such as oxytocin or apomorphine. The marketing case is customisation and faster onset.
Three things are worth knowing. None of these combinations has been through premarket review. Combining two PDE5 inhibitors with different half-lives is not a straightforwardly additive proposition and has not been tested for safety in that form. And they cost more than generics that have been tested.
The FDA has issued warning letters in this category as it has in the GLP-1 one, and the pattern of allegation is similar: claims implying a compounded preparation is equivalent to, or better than, an approved product.
The clinical point that gets skipped
Erectile dysfunction is frequently the first presenting sign of cardiovascular disease. The vascular endothelium in the penis is smaller-calibre than the coronary arteries, so it tends to show dysfunction earlier.
A consultation that prescribes a PDE5 inhibitor without asking about cardiovascular risk factors, blood pressure, diabetes or nitrate use is treating a symptom and skipping a screening opportunity. Nitrate co-administration in particular is a genuine contraindication with serious consequences, not a formality.
That is the question worth asking of any platform in this category: what did the intake actually assess?
How to compare providers here
- Is the medication an approved generic or a compounded formulation? If compounded, ask why.
- What is the cost per dose, not per month — usage is intermittent and monthly framing obscures it.
- Is a membership required to receive medication?
- What did the intake ask about cardiovascular risk and nitrates?
- Can you get the same generic through a retail pharmacy discount programme for less?
The last question is the one that resolves most of this category, and it is rarely posed.

Questions readers actually ask
Is generic sildenafil as good as Viagra?
Generics demonstrate bioequivalence to the reference product and are approved on that basis, which is why a pharmacist may substitute them.
Are compounded ED medications better?
They have not been through premarket review, are not bioequivalence-tested, and generally cost more than approved generics.
Why does ED need a cardiovascular check?
Erectile dysfunction is frequently an early sign of vascular disease, and nitrate co-administration with PDE5 inhibitors is a serious contraindication.
