HMB
What is it?
HMB is actually a metabolite of the amino acid L-leucine. L-leucine is one of three amino acids known as the branched chain amino acids or BCAA (isoleucine and valine being the other two).
It has been known for a long time that BCAA play a critical role in the turn over of lean body tissues (muscle) and is muscle sparing (i.e. anti-catabolic) in a variety of muscle wasting states. Of the three BCAA, L-leucine appears to be the most important to preserving hard earned muscle mass and intense exercise and certain disease states have been shown to eat up a great deal of L-leucine. So far so good!

BCAA’s
What is it?
In the world of amino acids, the structural “building blocks” of proteins, there are several classes and types of aminos. For example, we have the essential amino acids, the non-essential amino acids, the conditionally essential amino acids, and the branch chain amino acids (BCAA).
The essential amino acids are deemed as such because the body cannot manufacture them and they must be supplied by the diet. The non-essential amino acids can be made from the essential amino acids, and thus don’t have to be supplied by the diet for survival, though many non-essential amino acids play essential roles in health and metabolism in their own right.
What is it supposed to do?
The conditionally essential amino acids, so named because during certain periods, such as infancy or certain metabolic states, can be considered essential for that period of time. The branch chain amino acids (so named because they branch off another chain of atoms rather than form a straight line as other amino acids do) are leucine, valine and iso-leucine.
The BCAA’s are the amino acids that are primarily used (oxidized) during exercise and make up to one third of the amino acids in muscle tissue. It has been known for a long time that BCAA’s play a critical role in the turn over of lean body tissues (muscle) and is muscle sparing (i.e. anti-catabolic) in a variety of muscles wasting states. Of the three BCAA, L-leucine appears to be the most important to preserve hard earned muscle mass; intense exercise and certain disease states have been shown to eat up a great deal of L-leucine.

GH supplements

GH supplements
What is it?
There is a long list of supplements being sold claiming to either be Human Growth Hormone (HGH or GH) or cause the release of GH. The number of nutrients claiming to be able to increase HGH levels is long. The major products in this category currently being, marketed can be broken down into three major categories however. There is:
• Homeopathic GH claiming to contain actual HGH
• Growth hormone promoting nutrients (e.g., certain amino acids, vitamins, etc.)
• Secretagogues which are short peptides that supposedly cause a release of GH.
What is it supposed to do?
The role of GH in the human body is extensive and rather complicated with many effects still being elucidated. GH is known to play an essential role in the regulation of bodyfat levels, immunity, muscle mass, wound healing, bone mass, and literally thousands of other functions both known and yet unknown. Real human GH is a peptide 191 amino acids long with a molecular weight of approx. 20,000.
It is produced by the anterior pituitary gland, located at the base the brain. The bulk of the effect accomplished by GH is performed by a related hormone (Insulin-like Growth Factor-1 or IGF-1), which is released predominantly by the liver and, to some extent, by other tissues in response to GH levels. However, some recent data suggests GH has effects separate from that of its relation to IGF-1.
It is well established that GH levels steadily decline as we age and is partially responsible for the steady loss of muscle mass, loss of skin elasticity, immune disfunction, and many other physical changes that take place in the aging human body.
GH releasing nutrients claim to release GH and thus have the positive effects associated with GH.
