Research-based dosing protocols, timing guidance, and reconstitution reference for Buserelin. All information is for educational purposes only.

Quick Answer

Buserelin dosage depends on the indication and route of administration. For prostate cancer and endometriosis, subcutaneous or intranasal routes are common. For IVF, subcutaneous injection is typical. Consult a healthcare professional for precise dosing.

Standard Dosage Range

Research dosing range: Varies significantly by indication and formulation

Educational reference only

These dosage ranges are derived from preclinical research and community protocols. No human clinical dose-ranging trials have established therapeutic doses for most research peptides. Always consult a qualified healthcare provider before starting any peptide protocol.

Dosage by Use Case

Prostate Cancer (Advanced)

500 mcg (SC) 3× daily; or 150 mcg (nasal) 6× dailyAs directed by physician
Duration

Long-term (months to years)

Subcutaneous injection or nasal spray. Monitor testosterone levels. May require antiandrogen co-administration initially to mitigate flare.

Endometriosis

300 mcg (SC) 3× daily; or 150 mcg (nasal) 3-4× dailyAs directed by physician
Duration

3-6 months

Subcutaneous injection or nasal spray. Monitor estradiol levels. Bone density scans may be recommended for longer durations of treatment.

IVF (Long Protocol)

500 mcg (SC) dailyDaily, starting mid-luteal phase
Duration

Until HCG administration

Subcutaneous injection. Used to suppress ovulation and prevent premature LH surge. Dosage and timing are crucial and managed by a fertility specialist.

Timing & Frequency

For prostate cancer and endometriosis, doses are typically spaced evenly throughout the day. For IVF, dosing starts during the mid-luteal phase and continues until HCG administration.

Cycle Guidance

For prostate cancer, buserelin is often used long-term. For endometriosis, cycles are typically limited to 3-6 months. For IVF, the duration is dictated by the IVF protocol.
