For the best value, Optimum Nutrition Micronized Creatine ($21/120 servings) is hard to beat. If you want premium Creapure-sourced creatine, Momentous Creatine is the pick.

Dosing for Strength Athletes
The research is clear: 5g per day, every day. No cycling needed.
- Loading phase (optional): 20g/day split into 4 doses for 5-7 days, then 5g/day maintenance
- No-load approach: 5g/day from day one. Takes 3-4 weeks to fully saturate.
- Timing: Post-workout with protein is slightly better, but consistency matters more than timing.
FAQ
Is expensive creatine better than cheap creatine?
Not necessarily. All creatine monohydrate works the same way. The premium is for third-party testing (NSF) and sourcing (Creapure). If you're not a tested athlete, Optimum Nutrition works identically.
Do I need to cycle creatine?
No. 5g/day continuously is safe and effective. 30+ years of research shows no adverse effects from long-term use in healthy adults.
Does creatine cause water retention?
Creatine draws water into muscle cells, increasing weight by 1-3 lbs initially. This is intracellular water (inside the muscle), not bloating.
Is creatine safe for long-term use?
Yes. The ISSN position stand (Kreider et al., 2017) confirms creatine monohydrate is safe long-term with no adverse effects on kidney or liver function in healthy individuals.
