A Study of How the Body Absorbs LY3537031

The main purpose of this study is to find out how much LY3537031 gets into the blood stream and how long it takes the body to get rid of it when it is injected just under the skin in different parts of the body, and when it is injected into a vein, in healthy participants. This study will also look at the safety and tolerability of LY3537031.
