The 4-in-1 Breakthrough

Minutes to Start.
Hours to Spare.

Pills are slow. Our rapid-absorb liquid goes under your tongue and hits your system in as little as 10 minutes. One solution — four powerful ingredients.

1

PT-141

Ignites Desire

Acts centrally via the nervous system to heighten desire and arousal — bridging the gap between mind and body, independent of blood flow.

2

L-Citrulline

Rapid Flow

A potent nitric-oxide amplifier that primes circulation for a faster, fuller physical response.

3

Sildenafil

Peak Strength

The active ingredient in Viagra® — maximum rigidity when it counts, amplified by L-Citrulline's dual-strike effect.

4

Tadalafil

Lasts 36 Hours

The longest-lasting blood-flow agent available. Stays active up to 36 hours — so you never have to "time" intimacy again.

Four Actives. One Dose.

Engineered for
Every Stage.

Most treatments solve one problem. TETRA's four actives work in sequence — desire, strength, then staying power.

The Evidence

Four Actives.
Decades of Data.

We don't have testimonials to show you yet — TETRA is new. What we can show you is the clinical record behind every molecule in the formula, and exactly who is accountable for your prescription.

Sildenafil

FDA-approved 1998

The active ingredient in Viagra®. Among the most extensively studied PDE5 inhibitors in modern medicine, with more than two decades of published clinical use.

Tadalafil

FDA-approved 2003

The active ingredient in Cialis®. Characterized by the longest duration of action among approved PDE5 inhibitors — up to 36 hours per its approved labeling.

PT-141

Melanocortin pathway

Bremelanotide acts on melanocortin receptors in the central nervous system — a mechanism entirely distinct from blood-flow agents. Prescribed off-label in this formulation.

L-Citrulline

Nitric-oxide precursor

An amino acid the body converts to L-arginine, the direct substrate for nitric-oxide synthesis. Widely available and well characterized in the nutrition literature.

US-licensed clinician reviews every case
State-licensed pharmacy compounds and dispenses
No prescription without clinical approval

Compounded medications are not FDA-approved as combination products. Individual results vary. TETRA is available only where a licensed clinician determines it is appropriate.

US-licensed physician telehealth consultation
Doctor-Led Care

Real Medicine.
Real Oversight.

TETRA isn't a supplement — it's a prescription formula built on four clinically studied compounds, prescribed by US-licensed physicians when appropriate for you.

  • Sildenafil & tadalafil: FDA-approved actives with decades of clinical use
  • Compounded at US state-licensed partner pharmacies
  • Licensed provider review on every order — no exceptions
  • Ongoing support and dosage adjustments included

Confidence Is
The Real Result.

The point was never the prescription. It's showing up as yourself again — present, relaxed, and not thinking about it.
