Primary Outcome Measures:
  • Quantity of Growth Hormone [ Time Frame: 3 Weeks ] [ Designated as safety issue: No ]
    Measure human growth hormone at times -30, -15, 0, 30, 60, 90, and 120 minutes on two occasions about one week apart. On one occasion, the proprietary amino acid derivative blend will be given orally at time 0 in capsule form, and on the other occasion the capsules will contain no amino acids.

Secondary Outcome Measures:
  • Insulin-like growth factor 1 [ Time Frame: 3 Weeks ] [ Designated as safety issue: No ]
    Measure IGF-1 eight hours following the administration of the capsules containing the proprietary amino acid derivative blend or placebos.

Estimated Enrollment: 16
Study Start Date: October 2011
Estimated Study Completion Date: April 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: amino acid supplement
supplements with the proprietary amino acid derivative blend.
Drug: Amino acid supplement
An orally administered supplement of the proprietary amino acid derivative
Placebo Comparator: Placebo
Drug: Placebo
A non-active orally administered supplement of the proprietary amino acid derivative

Detailed Description:

Oral supplementation with a key combination of derivatives that has been shown to increase human growth hormone in healthy volunteers peaking at 90 minutes and IGF-1 at 8 hours post-administration.
