The honest comparison
Viagra was built
in 1998.
You weren't.
Sildenafil — the compound in Viagra® — is a good drug doing one job. Here's exactly where it stops, and what a 4-compound formula does differently.

To be fair to the little blue pill —
it changed everything in 1998, and if it still works perfectly for you, keep taking it. This page isn't for you.
It's for the man for whom it's become a planning exercise: take it early, skip the second glass of wine, hope tonight's a night it decides to work. Sildenafil does one thing — blood flow — and if your situation involves anything else, more sildenafil was never going to fix it.
"It takes too long"
A swallowed pill has to survive your stomach and liver first. VAST is sublingual — absorbed under the tongue, straight into the bloodstream.
"It stopped working"
Tolerance to a single compound is common. Four compounds at lower individual doses attack the problem from four directions instead of one climbing dose.
"It works, but something's missing"
Sildenafil can't touch desire — it was never designed to. VAST includes Apomorphine, which acts on arousal at the neurological level.

They decide whether the 4-compound formula is appropriate — including how to step off what you're on.

Ships discreetly. Your current prescription stays valid while you decide — nothing is burned by asking.
What men switching actually ask
Why did Viagra stop working for me?
Usually some mix of tolerance, age-related changes, and a psychological component the drug can't reach. It's common, and it isn't a dead end — it's a sign the single-compound approach has done what it can.
Is VAST just stronger Viagra?
No — it contains a lower dose of sildenafil than a typical Viagra prescription, plus three other compounds doing jobs sildenafil can't: faster onset, a multi-day window, and desire.
Can I take VAST if Viagra gave me side effects?
That's a clinician question, and it's exactly what the review is for — tell them what you experienced and they'll determine whether the formula and doses are appropriate for you.
What does it cost next to Viagra?
$114/month if prescribed, consultation and shipping included. Brand-name Viagra typically runs [$X] per tablet; generic sildenafil is cheaper but is the single compound this page is about.
