Sublingual speed
TETRA is a rapid dissolve tablet you place under your tongue, where the thin tissue allows the active ingredients to bypass your digestive system and enter your bloodstream directly.

No food rules
A heavy meal can blunt or even block a standard swallowed pill. Because TETRA skips the digestive system entirely, dinner and dessert stay on the menu. You never have to choose between a great meal and a great night.

The 36 hour window
With tadalafil in the blend, one dose of TETRA 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.

FAQ
Straight answers about Perstet TETRA, how it works, and what to expect.
Yes. It covers everything. You get the consultation, priority rush shipping, and the full 4-in-1 tablet pack. Because Perstet TETRA combines Vardenafil, Tadalafil, Sildenafil, and Apomorphine, you are effectively getting 4 treatments for the price of 1 (saving approx. 54% vs. retail buying them separately).
Potency and Speed. Competitors typically sell single ingredients in slow-acting pills. TETRA is a sublingual 4-in-1 rapid dissolve tablet (RDT). We combine the peak strength of Sildenafil, the rapid flow of Vardenafil, the 36-hour duration of Tadalafil, and the mental drive of Apomorphine into one fast-melting matrix. It absorbs directly through the tissues under your tongue, bypassing your digestive tract to hit your system faster. You get the combined power of all 4 active medications at once, lasting for up to 36 hours.
Unmatched physical reinforcement. Other custom platforms often dilute their formulas by swapping out heavy performance ingredients for gentle bonding hormones like Oxytocin. TETRA is the only platform that stacks all three major, clinically proven blood-flow inhibitors (Sildenafil + Tadalafil + Vardenafil) alongside Apomorphine. We don't skip the heavy hitters.
Because TETRA is formulated as a Rapid Dissolve Tablet (RDT), it should never be swallowed like a standard pill. Instead, place one tablet completely under your tongue (sublingually) or tucked flat between your upper gum and cheek (buccally). Let it dissolve entirely in your saliva. Avoid chewing, crushing, or swallowing the tablet, and try not to drink liquids for a few minutes while it dissolves. Do not take another TETRA tablet for 36 hours.
Bypassing the stomach allows the active ingredients to absorb directly through the sensitive blood vessels in your mouth. While standard pills take 30 to 60 minutes to process through your liver, TETRA begins absorbing immediately, with most users noticing the initial onset of effects in as little as 15 to 30 minutes.
No. You have full control. The medication simply "primes" your system. You stay ready for a 36-hour window, but the reaction only triggers when you are aroused. No awkward situations or loss of control. Just performance exactly when you need it.
Then you pay $0. We operate on a "Results or Refund" basis. If our US-licensed clinicians determine this specific compound isn't safe for you, the transaction is voided instantly. No hidden fees. No risk.
Apomorphine is a dopamine receptor agonist used off-label to trigger the brain signals that initiate an erection. It activates dopamine receptors in the hypothalamus, including the paraventricular nucleus, helping send the initial erectile signal through the spinal pathways. Unlike PDE5 inhibitors, which primarily support blood flow, apomorphine acts on the neural arousal pathway. It is typically administered sublingually and has been studied at 2 mg to 3 mg doses taken before sexual activity, with onset reported in roughly 15 to 30 minutes. References:
