No need to load up. Loading only gets you to muscle saturation quicker but is not required. In fact, some people with so much creatine in a day have stomach issues where they are fine if they skip the loading phase. 5g in a single dose per day is more than enough unless you are over 400lbs. Best taken post workout with your workout shake. That’s typical. Although it’s all about muscle saturation so you can take it any time. It’s not a pre-workout boosting supplement so timing isn’t as critical. Saturation is. It’s best taken with warm water, hot tea or your whey protein shake. As long as it’s properly mixed you should reap the benefits.
