Something that I find interesting is that our bodies can really only synthesize (on average) about 9 grams of creatine (from creatine monohydrate) a day. So, being a man of research and experience, I suggest you try a dosage of 10 grams for a loading phase. People do this anywhere from 1-2 weeks but I wouldn't load for more than two weeks because then you may just be wasting your creatine.
The science of creatine is that in our muscle tissues, we have ATP which stands for adenasine tri phosphate. This is the quick-grab energy that our body uses up in about 15 seconds of intense training whether it be sprinting, squatting or bench pressing. In each ATP molecule there are three creatine phosphate molecules attached. When you perform intense exercise, the creatine phosphate molecules explode (probably not the best word) and give off energy. But our bodies only produce so much creatine phosphate each day (the average person synthesis 1g daily- not counting the creatine obtained from beef and other animals products). When supplementing with creatine, whether it be monohydrate, ethyl esther, hydrocloride or any other, we are intaking these supplements in order to help build up the available store of creatine phosphate in our muscle tissues (so that when they "explode" and give off energy, they can be replaced in order to give off more energy again and again). When our bodies are fully saturated (whether you loaded or not), we have reached our maximum capacity (with the certain supplement and brand of creatine) to store creatine phosphate molecules in our muscle tissues.
Now, studies have shown (with creatine monohydrate- the most researched supplement) that when you consume creatine in any form over a period of time, your body stops synthesizing creatine phosphate on its own. It's like steroids in the way that because you are generating so much testosterone from the synthetic drug, the testes shrink because they no longer need to produce their own testosterone. However (going back to creatine), even when people have used it for years at a time and then go off it, when the body stops receiving it, it begins to produce creatine phosphate again on its own.
I suggest from both experience in research to cycle creatine. It's always a good idea because when the body stops producing something, you begin to rely on it. We all like to be independent people, don't we?!
