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.
Once muscle creatine stores are saturated, studies indicate that you only need to take 3 to 5 grams of creatine monohydrate per day in order to maintain elevated creatine stores. Most of the creatine is taken up by muscle during the first 2 to 3 days of the loading period.
