Did you know that some people respond to creatine, while others notice minimal effects from the elevated dose of creatine the body receives when supplementing. Creatine is one of the most Science backed supplements in the world, but trial it and gauge the effects on your body. If you notice minimal effects it could be possible that your body is not a genetic responder, therefore DO NOT insist on increasing the dose or take it for any longer than 4 weeks at a time in an attempt to make it work. Instead consider alternative supplements such as L-Arginine, a pre-workout containing L-Arginine and Beta-Alanine, or even Coenzyme Q10 (CoQ10).
