These are substances,
usually amino acids,
that are broken down in
the liver and converted into human growth hormone.
Advantages:
For short term use (assuming the dose is safe), this can be an effective
means of increasing HGH
levels. They are generally less expensive than the above categories. It may
be the most natural way to go - as long as your body is "up to"
producing more.
Disadvantages:
Most formulas come in too high a dosage. When the formula is stopped
suddenly, a person's GH levels then plummet below initial levels. Also If
your body isn't deficient in precursors then this type will not help you.
Side
Effects:
There are few side effects.
Extra substances the body doesn't use are just flushed out in your daily eliminations.
