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.
If kidney function begins to decline, BUN and creatinine rise. A normal creatinine depends on muscle mass and age. In general, a normal creatine is 0.5 to 1.2 milligrams per deciliter (mg/dL). A normal BUN is 7 to 20 mg/dL.
