Evaluation of Kisspeptin Stimulated Insulin Secretion With Hyperglycemic Clamp

Evaluation of Kisspeptin Stimulated Insulin Secretion With Hyperglycemic Clamp

The goal of this study is to understand how exogenous kisspeptin affects metabolism by evaluating responses to an hyperglycemic clamp

Assignment: Each study subject will serve as their own control. The order of the visits will be randomized.

Delivery of Interventions:

Prior to the study visit, subjects will undergo a review of their medical history and screening laboratories.

During the inpatient study, the subjects will
