Caffeine (Anhydrous) — Purified Methylxanthine (Capsules)

Research-grade caffeine (anhydrous) is a purified methylxanthine widely used in studies of alertness, reaction time, endurance performance, and metabolic activation. It primarily acts as an adenosine receptor antagonist with secondary effects on catecholamines and intracellular signaling (e.g., cAMP).

Identifiers

Synonyms: 1,3,7-Trimethylxanthine; Caffeine (anhydrous)
CAS No.: 58-08-2
Formula / MW: C₈H₁₀N₄O₂ • ~194.19 g·mol⁻¹
Class: Methylxanthine stimulant; adenosine A₁/A_2A antagonist

How It Works (Plain English)

Blocks adenosine receptors → reduces sleep pressure and perceived fatigue; increases cortical alertness.
Leads to higher neuronal firing and modest catecholamine release; downstream ↑ cAMP via phosphodiesterase effects at higher exposures.
In exercise studies, may lower perceived exertion and enhance endurance output (context- and dose-dependent).

Why Researchers Use It

To probe vigilance, reaction time, attention, and psychomotor performance.
To assess endurance and strength-endurance in sport/exercise physiology models.
To study metabolic rate, thermogenesis, and synergy with other actives (e.g., theanine).

Key Study Themes — What’s Typically Observed

Alertness, Reaction Time & Cognitive Throughput

Endpoints: PVT/RT, sustained attention, working memory accuracy.
Typical findings: Faster reaction times and improved vigilance, especially during sleep loss or circadian dips.
Notes: Inter-individual response varies with habitual intake, genotype (e.g., CYP1A2), and time of day.

Exercise & Metabolic Outcomes

Endpoints: Time-to-exhaustion, RPE, fat oxidation, HR/BP.
Typical findings: Small-to-moderate improvements in endurance performance; modest increases in metabolic rate.
Design tip: Standardize caffeine washout and dietary background (esp. habitual coffee use).

Potential Research Applications

Alertness & Shift-Work Models

Night-shift vigilance, sleep-restriction paradigms, driving simulators.

Sports & Exercise Physiology

Endurance time trials, RPE modulation, substrate utilization.

Metabolic & Thermogenic Studies

Resting energy expenditure, catecholamine panels, cAMP pathways.

Synergistic / Comparator Compounds

L-Theanine

Why pair: Classic combo—maintains alertness while smoothing perceived jitteriness.

NALT (N-Acetyl L-Tyrosine)

Why pair: Catecholamine precursor for attention under stress; compare combined vs solo effects.

Alpha-GPC

Why pair/compare: Cholinergic support for focus; contrasts dopaminergic/adenosine mechanisms.

Known Concerns (Context)

Cardio/CNS effects: Can increase heart rate, blood pressure, and anxiety/jitter in sensitive subjects.
Sleep disruption: Long half-life; avoid late testing if sleep metrics are endpoints.
Tolerance & withdrawal: Habituation may blunt effects; sudden cessation can cause headaches/fatigue.
General: For laboratory research use only; not for human consumption or therapeutic use.
