Very true. But, some people produce less creatine than their muscles can absorb, so adding it in to top off the muscles. But again, your right, if your muscles are absorbing as much creatine as they can, its just going to become waste. Thats why people know if creatine supplelmentation is needed in the first week of use. But, you cannot make the same argument for steroids. I mean, yes, your body produces a certain test level, and more test could potentially help you. And yes, some people are blessed with high test levels already. But, the difference is, you can naturally increase creatine levels through your diet. Test injections aren't part of your diet (haha). I do, however, beleive in naturally increasing test, through adequate sleep (~8hrs of sleep), doing compund lifts (Squat, Deadlifts, Power Cleans, Bench, Military Press, Barbell Curls) and somepeople feel through diet you can even tell the body to produce more test (Although I'm not familiar with the subject).
On the subject of sleep, here are some facts that I ran across on sleep. Decide for yourself if there true or not:
- Sleep is the BEST time for muscles to recover and grow. ~8hrs will permit adequate time to rebuild most muscle tissue.
- During sleep, the body experiences peak test and GH (growth hormones) in the body.
- Sleep timing could also make a possible difference (not sure of the source offhand). Every hour after midnight count as one hour of sleep. Everyhour before midnight, acts as 2 hrs of sleep for the body. For Ex: Sleeping from 12 midnight to 8AM is one hour longer than sleeping from 11PM to 6AM. But the body will experience the same recovery (although the latter was shorter), since one of those hours of sleep was an hour before midnight. [I think its limited to like 9-10PM to see these effects, and I'm not 100% sure and backing of this little tid bit, but I remember reading it in a few articles.]
- Not enough sleep one night? Power nap. Its shown that short, 20 minute naps have the same effect on the bady as one full hour of sleep at night (In a sense you can CATCH UP, not use this as a means of sleep).[Again, I read this tid bit in a few articles, just not sure which. I can find them upon request however.]
