What It Is

Know which part of the formula carries the evidence.

Sildenafil and tadalafil are PDE5 inhibitors with decades of clinical use behind the drug class. They support penile blood flow in response to sexual stimulation. Their timing profiles differ, but they work through the same core vascular pathway.

Oxytocin is different. It is a hormone and neuropeptide involved in social and reproductive biology, and some prescribers include it in compounded sexual-health formulations. Here, it gives your clinician a separate connection and experience layer to evaluate alongside the vascular components.

The PDE5 components bring established vascular pharmacology, while oxytocin brings a distinct social and reproductive signal. Your clinician decides whether those ingredients belong together in your individual prescription.

The vascular components and the exploratory component do different jobs. Sildenafil and tadalafil carry the established blood-flow evidence; oxytocin gives the clinician a separate connection and experience question to evaluate.

Who It's For

For the patient who wants the whole formula explained honestly.

01

The Step-Up Case

Standard single-agent therapy has already given your clinician useful information. You want the next decision based on that history rather than a generic escalation ladder.

02

The Evidence Reader

You want to know which ingredients are supported by established clinical pharmacology and which are more exploratory. You want that difference stated plainly.

03

The Individualized Patient

A compounded combination only interests you if a clinician can explain why this specific formulation belongs in your case.

Candidacy at these strengths is determined by a licensed provider from your full intake and your documented response, every time. This is not a formulation to escalate to on your own.

This might not be the right fit if:
  • Any use of nitrate medications, including nitroglycerin and isosorbide; combining PDE5 inhibitors with nitrates can cause a dangerous drop in blood pressure
  • Recent heart attack or stroke, or cardiac status your provider considers unstable
  • Severe hypotension, or uncontrolled high blood pressure
  • Alpha-blocker therapy requires particular provider caution at these strengths
  • Use of riociguat, or a prior serious reaction to sildenafil or tadalafil

Your intake screens for all contraindications. Every candidate is evaluated by a licensed clinician before any prescription is issued. No prescription is issued without clearance.

The Evidence

What the research shows

Two double-blind studies · 532 men · 24 weeks

On sildenafil alone, 69 percent of intercourse attempts succeeded versus 22 percent on placebo.

69% vs 22%
intercourse attempts that succeeded on sildenafil versus placebo
The detail

The sildenafil evidence is registration-grade and it is single-agent. In two sequential double-blind studies, 532 men were randomized to sildenafil 25, 50 or 100 mg or placebo over 24 weeks and 329 different men entered a 12-week flexible dose-escalation study; in the last four weeks of the dose-escalation study, 69 percent of intercourse attempts succeeded on sildenafil versus 22 percent on placebo, with 5.9 versus 1.5 successful attempts per month.1

Integrated analysis · five RCTs · 1112 men · 12 weeks

Tadalafil alone improved erectile function scores by 7.9 points.

7.9 points
mean gain in the erectile-function domain on tadalafil 20 mg
The detail

The tadalafil evidence is the same shape. In an integrated analysis of five randomized, double-blind, placebo-controlled 12-week trials in 1112 men of mean age 59, tadalafil 20 mg produced a mean 7.9 point improvement in the International Index of Erectile Function erectile-function domain, 75 percent of intercourse attempts were completed successfully on Sexual Encounter Profile question 3, and 81 percent reported improved erections versus 35 percent on placebo.2

Network meta-analysis · 82 RCTs · 47,626 patients

Sildenafil 50 mg ranked most efficacious, and no trial combined two PDE5 inhibitors.

82 trials · 47,626 patients
randomized evidence comparing PDE5 inhibitors, all single-agent
The detail

At class level the record is large and it is still single-agent. A network meta-analysis of 82 randomized trials covering 47,626 patients compared PDE5 inhibitors against placebo and against one another, finding sildenafil 50 mg most efficacious with the highest overall adverse-event rate and tadalafil 10 mg intermediate in efficacy with the lowest. No trial in that analysis combined two of them.3

2021 review · animal and human studies

Oxytocin’s sexual effects are animal findings; human studies did not confirm them.

The detail

The oxytocin evidence that exists is mostly preclinical, and the review literature says so. A 2021 review traces a laboratory-animal literature dating to the 1980s in which central oxytocin facilitates erection and sexual behaviour in male and female animals, and then reports that the human studies, conducted mainly with intranasal oxytocin, do not appear to confirm that facilitatory role in either men or women.4

What it does not show

Applicability

No trial has tested this three-ingredient tablet as sold.

The detail

No trial has tested this three-ingredient tablet as sold. There is no published randomized trial of sildenafil, tadalafil and oxytocin given together for erectile dysfunction. The approved labeling for both PDE5 ingredients states that combinations with other PDE5 inhibitors or with other treatments for erectile dysfunction have not been studied and that such combinations are not recommended. The single-agent results above belong to the single agents and do not carry over.56

Two crossover studies · intranasal oxytocin

Intranasal oxytocin did not change sexual drive, arousal or erection in men.

24 international units
intranasal oxytocin dose that did not alter sexual behaviour
The detail

The human oxytocin studies in men did not show the thing the ingredient is usually sold for. In a double-blind, placebo-controlled crossover experiment in 10 healthy men, 24 international units of intranasal oxytocin raised plasma oxytocin and epinephrine but did not alter appetitive, consummatory or refractory sexual behaviour on the scale used. In 29 heterosexual couples, 58 participants, the same intranasal dose did not alter sexual drive, arousal, penile erection or lubrication; the effects that did appear were on orgasm intensity, contentment after intercourse and partner interaction, with small to moderate effect sizes.78

22-week RCT · crossover · 30 women

The longest oxytocin trial was negative: placebo scored higher than oxytocin.

26% vs 31%
Female Sexual Function Index rise on oxytocin versus placebo
The detail

The longest randomized oxytocin trial in sexual dysfunction was negative. In a 22-week randomized, double-blind, placebo-controlled crossover trial in 30 premenopausal and postmenopausal women with sexual dysfunction, intranasal oxytocin 32 international units taken before intercourse raised Female Sexual Function Index scores by 26 percent while placebo raised them by 31 percent, with no significant treatment, sequence or interaction effect.9

Route

Every human study used intranasal oxytocin; no trial tested an oral dose.

The detail

The route studied is not the route sold. Every human sexual-function study cited here used intranasal oxytocin, and the FDA-approved oxytocin products are sterile injections given by intravenous infusion or intramuscular injection for obstetric indications, not for sexual function. No controlled trial establishes what an orally disintegrating oxytocin dose does. The tablet itself is compounded to an individual prescription, is not an FDA-approved drug product, and has not been through a trial programme of its own.78910

Important Safety Information

Serious risks

  • Approved labeling for sildenafil and tadalafil also documents an erection lasting more than four hours
  • Sudden decrease or loss of vision in one or both eyes
  • Sudden decrease or loss of hearing
  • Each of these needs urgent medical attention.
  • Both molecules lower blood pressure through the same pathway, and taking them together concentrates that effect
  • Antidiuretic activity with water retention and dangerously low blood sodium at high or prolonged exposure

Commonly reported

  • Headache
  • Flushing
  • Indigestion
  • Nasal congestion
  • Back pain
  • Muscle aches

Because it is an oral dissolving tablet

  • Safety data for an oral dissolving route at these doses are limited

The PDE5 ingredients carry most of what people report, and all of those effects appear in approved labeling. Your provider reviews nitrates, riociguat, alpha-blockers, other blood-pressure medication and cardiovascular history before prescribing. Oxytocin is the least settled part of the formulation for this purpose: FDA-approved oxytocin products are injections used under obstetric supervision, and their labeling documents an antidiuretic effect. The three-ingredient tablet itself is compounded to your individual prescription by a licensed 503A pharmacy and is not an FDA-approved drug product. A licensed clinician decides whether each component earns its place at the start, and keeps deciding at follow-up.
