A four-compound stack: Tadalafil 20mg + Sildenafil 70mg + Apomorphine 4mg — vascular and central-arousal support in one dose.
Tadalafil delivers 17-hour PDE5 coverage; sildenafil layers in fast onset.
Two PDE5 inhibitors together broaden and amplify vascular response.
Apomorphine activates central dopamine receptors — arousal signaling, not just mechanics.
Vascular + central pathways covered in a single dose.
