Quad X is a 4-in-1 prescription sexual enhancement tablet. Each tablet combines sildenafil 40 mg, tadalafil 4 mg, vardenafil 7.5 mg and apomorphine 2 mg to support blood flow and arousal for firmer, more reliable erections.
Viagra®, Cialis® and Levitra® each contain a single active ingredient: sildenafil, tadalafil or vardenafil. Quad X combines lower doses of all three PDE5 inhibitors with apomorphine, which acts on arousal pathways in the brain, so one tablet offers fast onset and longer-lasting support.
Sildenafil (the active ingredient in Viagra®) works fast, usually within 30 to 60 minutes, and lasts about 4 to 6 hours. Tadalafil (Cialis®) takes a little longer to start but lasts much longer. Vardenafil (Levitra®) works in a similar time frame to sildenafil. Instead of choosing one, Quad X combines all three with apomorphine for fast onset and longer-lasting support.
Don't combine separate erection pills on your own, because doubling up can lower blood pressure too much. Quad X combines lower doses of sildenafil, tadalafil and vardenafil in one tablet that a licensed provider prescribes only after reviewing your health history and medications.
Losing an erection midway is common and can be caused by stress, performance anxiety, alcohol, poor blood flow, low testosterone or some medications. Quad X supports both blood flow and arousal to help you keep an erection, and your provider can also look for underlying causes.
Most men take Quad X about 30 to 60 minutes before sexual activity. Sildenafil and vardenafil act quickly, while tadalafil helps extend the window of support. Sexual stimulation is still needed for an erection.
Effects from sildenafil and vardenafil typically last 4 to 6 hours, and tadalafil can extend support for longer. How long it lasts varies from person to person. Take no more than one tablet in 24 hours.
Apomorphine for men works in the brain on dopamine pathways involved in sexual arousal. It complements PDE5 inhibitors such as sildenafil, tadalafil and vardenafil, which work on blood flow, so Quad X supports both arousal and erection quality.
Never take Quad X with nitrates (such as nitroglycerin) or riociguat, because the combination can cause a dangerous drop in blood pressure. It may not be right if you have heart disease, very low or uncontrolled blood pressure, take alpha-blockers, or have serious liver or kidney problems. A licensed provider reviews your health history before prescribing.
Possible side effects include headache, flushing, nasal congestion, indigestion, dizziness and nausea. Seek medical help right away for chest pain, sudden vision or hearing loss, fainting, or an erection lasting more than 4 hours.
No single option is strongest for everyone. Sildenafil and vardenafil act quickly, while tadalafil lasts longer, and men respond differently to each. That's why Quad X combines sildenafil 40mg, tadalafil 4mg and vardenafil 7.5mg with apomorphine in one tablet, so you don't have to guess which one works best for you.
No. Quad Mix and Trimix are injections given directly into the penis. Quad X is an oral tablet that you take by mouth, with no needles.
No. Quad X is a prescription medication and isn't sold over the counter. You can get it online without an in-person visit: complete a short assessment, and a licensed provider decides whether it's right for you.
Yes. Complete a short online assessment, and a U.S.-licensed provider reviews your symptoms, health history and medications. If Quad X is right for you, it ships discreetly to your door. Quad X is $79 with no membership or hidden fees, and if you're not approved, you're not charged.
