Why Sublingual?
Fast Onset
Bypasses the digestive tract and liver. Compounds absorb directly into the bloodstream through the highly vascular oral mucosa.
Higher Bioavailability
First-pass metabolism in the liver degrades a significant portion of orally swallowed medications. Sublingual delivery avoids this loss entirely.
More Predictable
Without food and digestion variables affecting absorption, sublingual dosing produces more consistent, reliable effects every time.

Each vial contains 2mL — two doses per vial.
Frequently Asked Questions
Why combine four compounds instead of one?
Each compound works through a distinct mechanism. Apomorphine targets the brain’s dopamine system for desire. Sildenafil acts fast. Tadalafil lasts longest. Vardenafil adds high tissue selectivity. Together, they provide complete coverage that no single compound can achieve alone.
What is sublingual delivery and why does it matter?
Sublingual means under the tongue. The oral mucosa is highly vascular, allowing compounds to absorb directly into the bloodstream — bypassing the liver’s first-pass metabolism. This results in faster onset, higher bioavailability, and more predictable effects compared to swallowed tablets.
How do I take it?
Place 1mL under your tongue approximately 30 minutes before intimacy. Hold it there for 60–90 seconds before swallowing. Each vial contains 2mL (two doses). Avoid eating a large meal immediately before dosing.
Is it safe to combine all four compounds?
Yes. When compounded at these precise ratios by a licensed pharmacy and prescribed by a physician after reviewing your health profile, the combination is well-tolerated. Our physicians evaluate contraindications including nitrate medications before prescribing.
