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.
A dose of 5g of creatine daily for at least 8-weeks will increase muscle creatine. Traditionally, it was recommended to load creatine (25g daily, in divided doses) to quickly super-saturate your muscles for up to one week. Then, one would follow up the load with a maintenance dose of 5g per day.
