Muscle is muscle: There is a trace amount of creatine and creatinine in muscle meats which contributes slightly to urine creatinine, but most of it comes from the production of creatine in your own muscle. Creatine is used for short term storage of energy as creatine phosphate and some leaks out of your muscles every day. After a loading dose of 25 g per day for a week, 5 g creatine per day helps muscles work.
