How the figure above is derived, and when not to act on it.
Why Load Creatine?
Creatine monohydrate is a compound found naturally in muscle cells that helps produce energy during heavy lifting or high-intensity exercise. A loading phase saturates your muscle creatine stores significantly faster (1 week vs 4 weeks).The Science: Phosphocreatine (PCr)
Your body uses ATP for energy. During explosive movements (1-10 seconds), ATP runs out. Creatine donates a phosphate group to turn ADP *back* into ATP. * More Creatine = More Reps = More Volume = More Growth.The Loading Protocol (First 5-7 Days)
Take 0.3 grams per kg of body weight (or ~0.14g per lb). Start big to fill the tank. * Example (180 lbs / 82kg): ~25g Total Daily. * Split It Up: Take 4 doses of ~6g to avoid stomach upset.Loading vs. Maintenance
| Phase | Dosage | Duration | Purpose |
|---|---|---|---|
| Loading** | **20-25g / day | 5-7 Days | Saturate muscles fast |
| Maintenance** | **3-5g / day | Indefinite | Keep levels topped off |
| No-Load** | **3-5g / day | 30 Days | Slow saturation (no bloat) |
The Maintenance Phase (Week 2 Onwards)
Once saturated, you only need to replace what you degrade daily. * Standard Dose: 3-5g per day. * High Responders: Larger athletes (>220lbs) may need 5-8g.Hydration is Non-Negotiable
Creatine pulls water *into* the muscle cell (cell volumization). This is good (anabolic signal), but it requires water. * Drink 3-4 Liters of water daily during loading. * Cramping? You aren't "holding water," you are dehydrated. Drink more.Frequently Asked Questions
Q: Will I get bloated? A: "Bloat" is usually subcutaneous water (under the skin). Quality Creatine Monohydrate causes *intracellular* water retention (inside the muscle), making you look fuller and harder, not puffy.Q: Does creatine cause hair loss? A: One study in 2009 suggested a link to DHT. No study has ever replicated this. It is considered a myth by the ISSN.
Q: When should I take it? A: Post-workout with carbs is technically best for absorption (insulin spike), but consistency matters more than timing. Just take it daily.

Sports Science Articles- Creatine Supplementation: The Complete Evidence ReviewCreatine monohydrate is the most studied supplement in sports science. This is the full evidence base: loading protocols, the 20–30% vegetarian deficit, brain phosphocreatine, sarcopenia in over-55s, female-specific dosing, and why every "improved" formulation has failed head-to-head.16 min read
- The 60-Second Rest Period Is the Most Reflexively Applied Recommendation in Resistance Training. The PCr Resynthesis Data Suggests It's Wrong for Most Goals.Phosphocreatine (PCr) resynthesis reaches only 75% at 90 seconds post-set — the threshold for full replenishment is 3–5 minutes. Schoenfeld 2016 demonstrated that longer rest periods (3 min) produce significantly greater strength and hypertrophy gains than shorter rest (1 min) at equal volume.5 min read
