Further study details as provided by Pennington Biomedical Research Center:

Primary Outcome Measures:
  • Quantity of Growth Hormone [ Time Frame: 3 Weeks ]
    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 ]
    Measure IGF-1 eight hours following the administration of the capsules containing the proprietary amino acid derivative blend or placebos.

Enrollment: 19
Study Start Date: October 2011
Study Completion Date: March 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
