Eligibility Criteria

Age50 Years+
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy male subjects without recent severe diseases
  • Age 50 yrs or older
  • Body mass index at or below 30 kg/m2
  • Insulin-like growth factor-1 level below 200 ng/ml
  • Evidence of a personally signed and dated informed consent document indicating that the subject has been informed of all pertinent aspects of the trial
  • Subjects that are willing and able to comply with scheduled visits, treatment plan, laboratory tests and other study procedures

You may not qualify if:
