What is creatine, and can it help me get bigger?
Creatine monohydrate is an amino acid derivative that is incorporated into muscle as creatine phosphate. By regenerating ATP (fuel for muscle contractions) it can improve anaerobic endurance, strength, power and recovery between bouts (sets) of high intensity exercise. Associated with creatine use is a phenomena referred to as "volumization". This is an increase in cellular water content that helps to maintain an anabolic signal in the muscle cells. Over the long haul, this volumization may lead to greater muscular gains than the increase in strength and power alone.

Is creatine safe? What about its effects on my kidneys?
At the time of this writing, there are no know negative side effects associated with high dose, chronic creatine use. Weight gain was listed as a side effect, but isn't that why you take it?

If I want to increase my muscle size, would androstenedione be a good choice?
Androstenedione is one metabolic conversion away from testosterone in the body and it is hoped and believed that it increases testosterone levels in those using it. If you are a male, over 21 years old that has been working out for many years, have exhausted all other possible means to enhance muscle growth, are not under a doctors care or suffering from a medical condition and are unconcerned about the lack of available data on Androstenedione, then you may wish to use it.

Whey protein builds more muscle quicker than other complete proteins.
This is generally FALSE. The possible exception may be the underfed and over-trained athlete. For well-fed individuals, there is no nutritional advantage to whey protein over other complete proteins, except that one can consume less to meet protein requirements. No dietary protein initiates hypertrophy; appropriate exercise does.

Which amino acid supplement builds muscle quicker? Free-form amino acids or peptide bonded? Which is absorbed faster?
Neither builds muscle quicker. Muscle will build at its genetically predetermined pace as long as proper overall nutrition is combined with appropriate exercise. A combination of free-form and peptide-bonded amino acids is absorbed most quickly. However, there is no advantage to rapid absorption in the healthy population.

Why would someone need a full spectrum amino acid supplement or protein drink?
A full spectrum amino acid supplement provides a low-calorie protein substitute. A dislike for animal or dairy protein sources may create a need for this supplementation if skeletal muscle hypertrophy is the goal. High-energy output combined with restricted calorie intake
