The 4-in-1 on-demand dose
PERSTETTETRA
A drop under the tongue, about 15 minutes before. Only when you want it.
Never a daily pill
A typical pill carries one active ingredient.
Tetra carries four.
One drop. On demand.
Inside the drop
Four actives, running a relay
01 · Rapid onset
Vardenafil
On from ~10 min · peak ~40 min
The sprinter. First to switch on, covering you while the slower actives ramp.
02 · Peak blood flow
Sildenafil
On from ~20 min · peak ~75 min
The workhorse. Carries peak blood flow through the middle hours.
03 · Drive
Apomorphine
On from ~10 min · peak ~35 min
Works in the brain, not the bloodstream. Primes the arousal signal so your body answers faster.
04 · Duration
Tadalafil
On from ~45 min · holds up to 36 hours
The marathon. Takes the handoff and keeps the window open.
The engineering
One dose, assembled
Formula
Vardenafil, sildenafil, tadalafil, apomorphine. Compounded to order.
Onset
Take it about 10 to 15 minutes before. Sublingual, so it skips digestion.
Window
One dose can stay effective up to 36 hours. Still working the next morning.
Care
A licensed clinician reviews your history and signs off before anything ships.
Delivery
Plain packaging. Nothing on the outside says what is inside.
Sublingual speed
Ready in minutes
Tetra is a fast absorbing liquid you place under your tongue. It reaches your bloodstream through the tissue there, skipping the stomach and liver entirely, so it goes to work far sooner than a pill you swallow.
- No more waiting an hour or longer
- Can be working in as little as 15 minutes
- Quiet, total control of the moment
No food rules
Dinner and performance
A heavy meal can blunt or even block a standard swallowed pill. Because Tetra absorbs under the tongue, dinner and dessert stay on the menu. You never have to choose between a great meal and a great night.
- Food will not block absorption
- No empty stomach rules to follow
- Real spontaneity, back on the table
The 36 hour window
Ready when you are
With tadalafil in the blend, one dose does more than cover the moment. It can keep you responsive for up to 36 hours, so the window stays open instead of slamming shut.
- No more clock watching before the moment
- Coverage that can last all weekend
- Ready for a second round, or a third
