The main purpose of this study is to evaluate the safety and tolerability of two different devices that may be used to inject medication just under the skin. Participants will receive placebo; no active drug will be given. The study will last up to five weeks for each participant, including a one-week overnight stay in the study center.

Inclusion Criteria:

• Overtly healthy male or female participants as determined by medical history, laboratory tests, physical examination, 12-lead ECGs, and vital signs.
• Body mass index (BMI) within the range of 18 to 32 kilograms per meter squared (kg/m²)
• Female participants must not be pregnant, and must test negative for pregnancy
• Agree to video recording during each administration event using the autoinjector or bolus injector

• Have tattoos or scars over the abdomen, or other factors (eg, rash, excessive folds of skin) that, in the investigator's opinion, would interfere with injection-site assessments
