Does anyone use Runners Advantage Creatine Serum to help with endurance? If so, does it work? I'm currently training for my first marathon and my goal is to qualify for Boston. If this stuff is of any benefit in my efforts I may be interested in trying it. I've seen this stuff advertised every month for several years in Triathlete and Runners World.
I'm 46 and have only been running for just over 2 years. I've done about 15 sprint and Oly tris and if my marathon goes well I will move up to longer events. The run is my weakness and I'm currently training with a coach to help improve this.
