A Study of 2 Different Formulations of Insulin Lispro in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
The study involves 4 injections of insulin lispro and its purpose is to: Determine if 2 formulations of insulin lispro are treated by the body in a similar way. Compare how the 2 formulations of insulin lispro affect blood sugar level. Determine the safety of each insulin lispro formulations and any side effects that might be associated with them when given to healthy participants. The study is expected to last up to approximately 9 weeks for each participant.
