No, your reception is fine. What you're experiencing is sound attenuation, the loss of energy from sound waves. Basically, attenuation is a damping of sound, an interruption that diminishes the volume and quality of the sound wave.
No, this is not necessary. A mere 3 grams of creatine per day for 28 days results in the same muscle content of creatine as that of a six day load program. Thus, if you wanted to get off creatine, it would take about a month to reach normal muscle stores.
Creatine is normally found in meat and fish. Creatine is also naturally made in the human body in the kidney and liver. Creatine is mainly stored in muscles, but about 1.5-2% of the body's creatine is converted to creatinine daily.
