Sildenafil rapid dissolve tablet
Prescription-gated and properly labelled — but 115mg is above sildenafil’s ceiling.

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 we take no affiliate commission or referral fee from anyone named here — including from the retail pharmacies whose generics we rate most highly.
A compounded sublingual sildenafil that will not be sold to you without a prescription, and that publishes its contraindications in full. Good practice, with one strength that sits above the approved ceiling.

Our assessment
Judged as a compounding pharmacy rather than a direct-to-consumer brand, this is largely how it should be done. A prescription is required, so a clinician has made the decision. The compounding disclosure is stated in the company’s own plain words. And the safety information published here is the most complete of anything reviewed on this page — nitrates and riociguat both named, the cardiac and ophthalmic contraindications listed, and priapism identified as an emergency.
Set that against the direct-to-consumer compounded products further down this page, several of which publish multiplier claims and no contraindications at all. Same regulatory category, entirely different conduct.
The strengths are where we would raise a hand. 17, 36, 60 and 80mg are unusual numbers but all sit under sildenafil’s approved 100mg ceiling, and a prescriber choosing a non-standard dose for a particular patient is exactly what compounding is for. 115mg is different — it is above the maximum approved single dose, and a prescriber ordering it should be able to say why, because the evidence that made sildenafil first-line therapy stops at 100.
The onset claim of 15 to 30 minutes also deserves the same scrutiny we have applied elsewhere. The best randomised evidence comparing a dissolving sildenafil against ordinary tablets found a difference of about seven minutes that did not reach statistical significance, with onset in both arms closer to fifty minutes. We have written that up separately; it is worth reading before choosing a format on speed.
Reasonable for
- Men whose prescriber has specified a compounded sublingual at a particular strength
- Men who need a dose or a format no manufactured product provides
- Men who want a compounded product from a pharmacy that publishes its risks properly
Not for
- Anyone taking nitrates or riociguat
- Men without a prescription — this pharmacy will not supply one
- Men considering the 115mg strength without a prescriber who can justify exceeding the approved maximum
- Men choosing a dissolving format because they expect it to be dramatically faster
