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 both synthesized in the body and derived from foods such as milk, red meat, and some fish. Adults need to synthesize and ingest a total of about 2 grams of creatine daily to make up for the urinary loss of creatinine, the breakdown product of creatine.
