Quad — Sexual Health — Men

The formula

What each ingredient does

Sildenafil 40mg

A PDE5 inhibitor that supports blood flow by blocking the PDE5 enzyme, one of the most commonly prescribed ED ingredients in use.

Tadalafil 4mg

A second PDE5 inhibitor, included here at a low dose. Within the class, tadalafil is known for its long duration window.

Vardenafil 7.5mg

A third PDE5 inhibitor, known in the class for its selectivity for the PDE5 enzyme. It works through the same blood-flow pathway as sildenafil and tadalafil.

Apomorphine 2mg

Acts on dopamine receptors in the central nervous system involved in sexual-response signaling, adding a central pathway alongside the three blood-flow ingredients.

Possible side effects of PDE5 inhibitors may include headache, flushing, nasal congestion, dizziness, indigestion, back pain, vision changes, low blood pressure, and rare but serious events such as priapism or sudden vision/hearing loss. Apomorphine may cause nausea, dizziness, sleepiness, low blood pressure, or fainting in some patients. Do not use with nitrates. Tell your provider about all heart medications and blood-pressure medications before use. Tell your provider about all medical conditions and medications during your assessment.
