The short answer
A compounded dissolving tablet that pairs tadalafil, the long-window erection medicine, with a low dose of oxytocin, the hormone people associate with closeness. Three strengths, from a low daily-style dose to a full as-needed dose. Oxytocin’s use here is off-label with limited evidence. Prepared by a licensed compounding pharmacy and not FDA-approved.
- Tadalafil opens a window of up to 36 hours. That is an opportunity to respond to stimulation, not an erection lasting 36 hours.
- Trot is a low, daily-style dose; Canter and Gallop are as-needed strengths. Daily and as-needed regimens have different instructions. Follow your clinician’s plan, never both.
- Oxytocin here is off-label and compounded. The evidence for sexual-health benefit is limited and mixed; tadalafil does the heavy lifting.
- Never combine with nitrates (including nitroglycerin), poppers, riociguat, cocaine, or another erection medicine.
The long window.
Tadalafil is the erection medicine with the longest reach: as-needed doses can support erectile response for up to 36 hours, and a low daily dose keeps a steady level so nothing has to be planned. Either way, arousal is still required and your size does not change. The Long Rider puts tadalafil in a tablet that dissolves in your mouth.1
About the oxytocin.
Oxytocin is a hormone the body releases around touch, orgasm and bonding, which is why people talk about it for connection. The research on giving it for sexual health is small and mixed: one randomized trial found effects on some aspects of sexual experience without improving desire or erectile function. Its use in this tablet is off-label, and we do not promise a chemistry effect. If the tadalafil is doing its job and the oxytocin is doing nothing, you will still have had a good night.2
Trot, Canter, Gallop.
Three strengths of tadalafil, each with 100 IU of oxytocin. Trot is 5 mg, the tadalafil dose that is often taken once daily. Canter is 10 mg and Gallop is 20 mg, the as-needed strengths. Your clinician chooses the strength and the rhythm with you and can change either at the week-two check-in. Never take the daily and the as-needed regimens together, and never add another erection medicine.1
Possible side effects
From the tadalafil: headache, indigestion, flushing, stuffy nose, back pain and muscle aches; heavy alcohol adds dizziness and low blood pressure. From low-dose oral oxytocin the data are thin; headache and nausea have been reported with oxytocin by other routes, and the fluid-balance and cardiovascular risks known from oxytocin injection cannot be directly measured for a compounded tablet. An erection lasting four hours is an emergency.3
Compounded and off-label. Here is what that means.
This tablet is prepared for you by a licensed compounding pharmacy on a clinician’s prescription. It is not FDA-approved, and the FDA has not reviewed the combination for safety, effectiveness or quality. Tadalafil on its own is available as FDA-approved tablets from a retail pharmacy; this is not one of those products. The approved oxytocin product is an injection with obstetric uses; oxytocin for men’s sexual health is off-label.4
Give your clinician the whole picture.
Cardiovascular health, blood pressure, kidney or liver problems, and every medicine, supplement and recreational drug. Nitrates, poppers and riociguat rule out tadalafil entirely. Cocaine and other stimulants must never be combined with it. Blood-pressure, prostate, antiviral and antifungal medicines need extra review.1
