Creatine Monohydrate vs Hydrolyzed Cluster Dextrin

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

Best Stacking Partners

Mechanism

Low-osmolality cyclic glucose polymer that supports gastric emptying and intra-session carbohydrate delivery with less GI burden than many simpler carbs.

Contraindications

• Use cautiously in clients with poor glucose control
