The complete male performance protocol. Prescription-grade PDE5 inhibition paired with nitric oxide precursors, essential minerals for testosterone support, and adaptogenic stress reduction.
arq Edge is the performance optimization pack that combines pharmaceutical PDE5 inhibition (Sildenafil 50mg) with nitric oxide enhancement (L-Citrulline 3g), testosterone support (Zinc 30mg), and stress resilience (Ashwagandha KSM-66 600mg). It's built on your bloodwork and hormone levels, addressing vascular, hormonal, and psychological dimensions of male performance in a single 30-minute-onset protocol.
arq Edge combines pharmaceutical PDE5 inhibition with targeted nutritional support for vascular and hormonal optimization. Each component addresses a distinct mechanism—from immediate vasodilation to sustained nitric oxide production and stress resilience.
| Component | Dosage | What It Targets | Monitoring |
|---|---|---|---|
| Sildenafil | 50mg | Vascular dilation, immediate blood flow | Efficacy, side effects |
| L-Citrulline | 3g | Nitric oxide production, sustained vascular support | Synergy with Sildenafil |
| Zinc Picolinate | 30mg | Testosterone synthesis, male sexual function | Serum zinc, testosterone levels |
| Ashwagandha KSM-66 | 600mg | Cortisol reduction, performance anxiety, confidence | Cortisol rhythm, subjective experience |
L-Citrulline enhances nitric oxide production, amplifying Sildenafil's vascular effects beyond the initial 30-minute window. Zinc supports testosterone synthesis and male sexual function—deficiency alone causes dysfunction. Ashwagandha KSM-66 reduces cortisol and performance anxiety, addressing the #1 psychological cause of ED. Together, this stack addresses vascular, hormonal, and psychological dimensions of performance.
This stack combines a wakefulness promoter, a vasodilator for tissue perfusion, and an adaptogen. Timing is critical to avoid unwanted sympathomimetic stacking.
| Modafinil | Tmax 2–4h, t½ 12–15h, ~80% bioavail |
| Sildenafil | Tmax 0.5–2h, t½ 3–5h, ~40% bioavail, CYP3A4 |
| L-Citrulline | Tmax 1h, t½ 1h (converts to arginine), high bioavail |
| Ashwagandha KSM-66 | Tmax 2–3h, t½ 6–12h, bioavail variable |
| Key note | Sildenafil is optional/as-needed; don't dose daily without Rx |
arq Edge stacks cognition with physical endurance and vascular function. Sildenafil is situational (not daily unless medically appropriate), while Modafinil and Ashwagandha form the base layer.
Each component has robust safety and efficacy data. The combination creates synergy through complementary mechanisms (CNS + vascular + endocrine).
Both modafinil and sildenafil can independently cause headache. Magnesium supplementation (separate from this stack) is recommended if this emerges.
Both modafinil and sildenafil are CYP3A4 substrates. Modafinil may slightly decrease sildenafil bioavailability, but clinically insignificant. The key concern is with external medications.
Book a consultation with a licensed physician to discuss whether arq Edge is appropriate for you.
