You may qualify if…

Healthy adult Caucasian female volunteers, 18-45 years of age, inclusive, at the time of consent.
Body Mass Index (BMI) greater than (>)18.5 and less than or equal to (<=) 30.0 kilograms per square meter (kg/m\^2) (inclusive) at the time of screening.
Body weight greater than or equal to (>=) 45.0 kilograms (kg) at the time of screening.
The participant is considered by the investigator to be in good general health, defined as absence of clinically significant illness or surgery within 4 weeks prior to dosing, and no clinically significant history of neurological, endocrine, cardiovascular, respiratory, hematological, immunological, psychiatric, gastrointestinal, renal, hepatic, or metabolic disease as determined by medical history, clinical laboratory test results vital sign measurements (systolic blood pressure [BP] >=90 millimiters of mercury [mmHg] and <=145 mmHg, diastolic BP >=50 mmHg and <=95 mmHg), 12-lead ECG results, and physical examination findings at screening and check-in (congenital nonhaemolytic hyperbilirubinemia [for example Gilbert's syndrome] and/or abnormal findings without clinical significance are acceptable).
Absence of tattoos, scars, or any skin conditions, including infections or open wounds, or dermatitis at the injection site that could interfere with the evaluation of injection reaction.
All participants of childbearing potential must have a negative pregnancy test at screening and check-in and must agree to use a highly effective method of contraception from screening through study completion and for 30 days after the last dose. Acceptable highly effective methods of contraception include intrauterine device (IUD)/ intrauterine system (IUS), bilateral tubal occlusion, exclusive relationship with a vasectomized partner with documented azoospermia, sexual abstinence (if this is the participant's usual lifestyle) or exclusively engaging in a same-sex relationship. Male partners of female participants should also use a condom. Hormonal methods for contraception (including a hormone-releasing intrauterine system such as Mirena) or double-barrier methods (e.g., male condom with diaphragm or cervical cap) are not permitted.
The participant must be able to comprehend and willing to sign an informed consent form (ICF) and to abide by the study restrictions. Participants must have signed an ICF before any study-related procedure or evaluation is performed.

You may not qualify if…
