🧬 Introduction – What is Susten 100 mg Injection?

Susten 100 mg Injection contains natural micronized progesterone, a crucial hormone used to regulate ovulation, support early pregnancy, and manage hormonal imbalances. Manufactured by Sun Pharmaceutical Industries Ltd, this intramuscular injection is widely prescribed in reproductive medicine and gynecological therapy.

Progesterone plays a vital role in preparing the endometrium for embryo implantation, sustaining early pregnancy, and correcting luteal phase deficiencies. Susten 100 mg is often used during IVF cycles, threatened miscarriage, and hormone replacement therapy (HRT) programs.

Its high-quality formulation ensures consistent hormone levels with minimal side effects, making it a preferred choice in fertility treatments globally.
