Triptorelin is a synthetic GnRH (gonadotropin-releasing hormone) agonist that is 100x more potent than natural GnRH. It is FDA-approved under brand names Trelstar and Triptodur for prostate cancer treatment and central precocious puberty. When administered continuously, it paradoxically suppresses reproductive hormones (LH, FSH, testosterone, estrogen) through receptor desensitization - a process called "chemical castration."
The initial effect of triptorelin is stimulatory (a "flare" of LH/testosterone), followed by profound suppression within 2-4 weeks of continuous administration. This dual-phase pharmacology is clinically exploited: the suppressive phase is used in prostate cancer, endometriosis, and precocious puberty treatment.
Key Research Findings
- •FDA-approved for prostate cancer (Trelstar) and central precocious puberty (Triptodur)
- •100x more potent than natural GnRH at the GnRH receptor
- •Initial stimulatory 'flare' followed by profound LH/FSH suppression with continuous use
- •Reduces testosterone to castrate levels within 2-4 weeks of continuous administration
- •Used in fertility medicine (IVF protocols) to prevent premature ovulation
Research Dosage Protocols
Triptorelin is FDA-approved at doses of 3.75 mg monthly or 11.25 mg quarterly (depot injections) for prostate cancer. Research-grade triptorelin is available as lyophilized powder.

Frequently Asked Questions
What is triptorelin?
Triptorelin is an FDA-approved GnRH agonist 100x more potent than natural GnRH. With continuous use, it paradoxically suppresses reproductive hormones. It is used for prostate cancer, precocious puberty, and IVF.
Does triptorelin increase or decrease testosterone?
Both. A single dose causes an initial LH/testosterone spike ('flare'). Continuous administration causes profound suppression within 2-4 weeks through GnRH receptor desensitization.
