The 12-hour clarity protocol. Pharmaceutical-grade wakefulness combined with three targeted nootropic supplements that smooth the cognitive curve, support cholinergic signaling, and protect against overstimulation.
arq Focus is the cognitive performance pack that addresses brain fog, concentration, and mental clarity through a combination of modafinil (pharmaceutical wakefulness), L-Theanine (smooth stimulation), Alpha-GPC (acetylcholine support), and magnesium glycinate (stress modulation). Designed for 12+ hours of sustained focus without crash or overstimulation, optimized through your baseline bloodwork.
arq Focus combines pharmaceutical precision with targeted nutritional support. Each component serves a specific role in the stack, creating a synergistic protocol that extends your clarity window while protecting against overstimulation.
| Component | Dosage | Cognitive Target | Duration |
|---|---|---|---|
| Modafinil | 200mg | Sustained wakefulness, prefrontal focus | 12-15h |
| L-Theanine | 200mg | Smooth stimulation, alpha wave support | 4-6h |
| Alpha-GPC | 600mg | Acetylcholine synthesis, learning | 6-8h |
| Magnesium Glycinate | 300mg | Stress modulation, neural stability | Sustained |
L-Theanine counteracts Modafinil's occasional edge or anxiety by promoting relaxed alertness without sedation. Alpha-GPC feeds the acetylcholine system, amplifying working memory and processing speed when combined with Modafinil's dopaminergic effects. Magnesium Glycinate supports GABA signaling for calm focus and prevents the tension headaches some users report. Together, these four molecules create a smooth, extended clarity protocol that scales from morning focus sessions through afternoon deep work.
Each component has a distinct pharmacokinetic signature. Understanding how they layer over time optimizes the synergistic window and peak cognitive impact.
| Modafinil | Tmax 2–4h, t½ 12–15h, ~80% bioavail |
| L-Theanine | Tmax 0.5–1h, t½ 1.2h, high bioavail |
| Alpha-GPC | Tmax 1–2h, t½ 4–6h, ~88% bioavail |
| Mg Glycinate | Tmax 3–4h, t½ N/A (mineral), ~80% bioavail |
| Peak synergy window | 4–8h post-dosing (all components active) |
| Metabolism | Modafinil: CYP3A4/2C19. Others: minimal hepatic metabolism |
The four-molecule stack requires careful timing to avoid competition for absorption and to maintain the extended focus window without sleep disruption.
While no published trials specifically test this four-component combination, evidence for each component supports the synergistic rationale.
This stack is designed to be self-mitigating. L-Theanine buffers modafinil-induced anxiety; Magnesium reduces headaches. Combined safety profile is excellent.
Modafinil is the primary driver of drug interactions in this stack. L-Theanine, Alpha-GPC, and Magnesium Glycinate have negligible hepatic metabolism.
