I take 45 minutes before training 2 capsules, although I as 50ig years, experienced bodybuilders could take twice as much (who has never taken creatine). On days I do not take Krealkalin, although it should be taken for optimal results also traingsfreien days in the morning on an empty stomach. I've had enough, the additional power by taking 2 capsules on training days, which does not go unnoticed, and after several days increases the strength, the muscles grow. No problems with digestion. I love the sport with Krealkalin Nitro Pro even more fun and you can see positive results quickly. Can recommend with a clear conscience this preparation.
