Question: how long does it take to gain weight on creatine?
Answer: The average weight gain for adults in the first week of Creatine loading is about 1.5-3.5 pounds, though that weight gain may be due to the water retention. An athlete that is on Creatine for up to 3 months will gain up to 6.5 pounds of lean mass more than an athlete that is not training with Creatine.
