Creatine Monohydrate vs Epicatechin

Mechanism

Creatine is phosphorylated by creatine kinase to phosphocreatine (PCr), which serves as a rapid phosphate donor to regenerate ATP from ADP during high-intensity, short-duration activity (the phosphagen energy system). This extends maximal effort capacity by 10-20%. Beyond energy, creatine enhances satellite cell activation and myonuclear addition, increases intracellular water retention (cell volumization signals anabolism), upregulates IGF-1 locally in muscle, enhances glycogen supercompensation, and crosses the blood-brain barrier where it supports cognitive function under stress (brain PCr buffer). It also acts as a direct antioxidant, scavenging reactive oxygen species.

Standard Dosing

5g daily (no loading necessary, but loading is faster)

Timing

Post-workout with carbohydrates and protein for optimal uptake (insulin-mediated GLUT4/creatine transporter co-localization). On rest days, any time with a meal. Dissolve in warm water for solubility.

Cycle Duration

ongoing (no cycling necessary — the 'cycling creatine' myth has been debunked)

Side Effects

• Weight gain (1-3 kg from water retention — intracellular, not bloat)
• GI discomfort at high doses
• Muscle cramping (anecdotal, not confirmed in controlled trials)
• Elevated serum creatinine (expected, benign — not indicative of renal damage)

Contraindications

• Pre-existing renal disease (creatinine levels will rise, which is expected and does not indicate kidney damage in healthy individuals)
• Rare: renal tubular disorders

Mechanism

Cacao-derived flavanol that inhibits myostatin and increases follistatin, shifting the balance toward muscle growth. Also stimulates mitochondrial biogenesis and nitric oxide production. Improves grip strength and muscle recovery without being anabolic in the traditional sense.

Contraindications

• None established
