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.
The lower sides of creatine dosage recommendations are to take from 2 to 5 grams a day (non-loading or post loading). Higher creatine dosage recommendations call for quantities as high as 20 to 30 grams a day. Ultimately, the ideal creatine dosage for you will have to be found through trial and error.
