Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Healthy males or females aged 18 through 50 years. 2. Male subjects with a weight of ≥50 kg, female subjects with a weight of ≥45 kg, and BMI between 19.0 and 26.0 kg/m² (inclusive). 3. Male subjects and their partners, or female subjects, must agree to use one or more non-pharmacological contraceptive measures during the trial and up to 6 months after the end of the trial (such as complete abstinence, condoms, intrauterine devices, partner sterilization, etc.), and should have no plans for sperm or egg donation. 4. The upper limits for hemoglobin (Hb) and hematocrit (HCT) are 165 g/L and 49%, respectively, for males, and 150 g/L and 45%, respectively, for females. 5. Subjects have a full understanding of the trial's purpose, nature, methods, and potential adverse reactions, voluntarily agree to participate in the trial, and sign the informed consent form. 6. Subjects can communicate effectively with the researchers and can comply with the study protocol as specified. Exclusion Criteria: 1. Family history of early-onset coronary artery disease, including first- or second-degree relatives diagnosed with coronary heart disease or angina before the age of 50; any family history of hematological disorders, such as thrombosis or increased clotting risk, or any family history of deep vein thrombosis, pulmonary embolism, stroke, hemolytic anemia, or hemoglobinopathies; family history of hypertension. Alternatively, the subject has a personal medical history of the aforementioned conditions. 2. Presence of liver or kidney diseases or conditions affecting drug absorption, distribution, metabolism, or excretion, including other medical situations such as surgical procedures, trauma, etc. that may interfere with these processes. 3.

Clear history of drug allergy or specific hypersensitivity reactions (asthma, urticaria, allergic rhinitis, eczematous dermatitis); known allergies to the investigational drug and excipients, or allergies to similar drugs; individuals intolerant to subcutaneous injections or with a history of fainting during needle procedures. 7. Use of erythropoiesis-stimulating agents or treatment with other biologics within the six months prior to screening. 8. Participation in any other drug clinical trial within the 3 months prior to screening or within 5 half-lives of any investigational drug from other clinical trials (selecting the longer time period). 9.
