9. Patients who voluntarily sign an IRB-approved informed consent form before the screening visit, are willing to abide by the restrictions of the study, and complete the prescribed examinations.

Exclusion Criteria:

1. Patients with prostate cancer who receive previous or ongoing endocrine therapy (surgical castration or other endocrine therapy including GnRH receptor agonists, GnRH receptor antagonists, anti-androgens, estrogens, megestrol acetate, etc.), except for patients with prostate cancer undergoing prostatectomy, radiotherapy or cryotherapy who have received neoadjuvant/adjuvant endocrine therapy for no more than 6 months and discontinued the above therapy more than 6 months before screening.
2. Has received prostatic surgery within 4 weeks prior to the Screening Visit, or plan to receive surgical treatment during the trial.
3. Patients with confirmed or suspected hormone-resistant prostate cancer.
4. Has previously received hypophysectomy or adrenalectomy, or who have pituitary lesions.
5. Has received 5-α reductase inhibitors (finasteride, dutasteride, eridasteride, etc.) within 1 month before the first dose.
6. Has previously received goserelin.
7. Has received an investigational drug, an investigational biological product or an investigational medical device, and discontinued within 1 month or 5 half-lives of the corresponding drug before the screening visit, whichever is longer.
8. History of severe asthma, anaphylaxis, or severe urticaria and/or angioedema.
9. History or presence of another malignancy, other than surgically removed squamous/basal cell carcinoma of the skin, within the last 5 years.

15. Alcoholics, drug addicts or drug abusers.
16. Patients of childbearing potential who refuse using effective contraception during the entire trial.
17. Patients with viral hepatitis B who are taking anti-hepatitis B virus (HBV) drugs or need drug treatment (those who need drug treatment must meet the following 2 conditions at the same time: 1. HBV DNA level: HBeAg-positive patients, HBV DNA ≥ 20,000 IU/ml [equivalent to 10^5 copies/mL]; HBeAg-negative patients, HBV DNA ≥ 2,000 IU/ml [equivalent to 10^4 copies/mL]; 2. ALT ≥ 2 x ULN).
18. Patients who are seropositive for hepatitis C virus (HCV) antibody or human immunodeficiency virus (HIV) antibody.
19. Known to be allergic to the active ingredients or any excipients of the investigational drug, or other GnRH analogues.
