Leuprolide- Summary
- Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.
- Leuprolide is a synthetic GnRH superagonist that, with continuous administration, paradoxically suppresses LH and FSH through receptor desensitization — the opposite effect of pulsatile GnRH. Used medically for prostate cancer, endometriosis, and precocious puberty. In men's health, short-duration use for PCT and testosterone suppression rebound.

- Key Benefits
- Potent appetite suppression via triple monoamine reuptake inhibition
- Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
- Increases basal metabolic rate and energy expenditure
- Reduces fat mass preferentially over lean mass
- Potential cognitive benefit via dopaminergic and noradrenergic enhancement
- Longer half-life than sibutramine allows once-daily dosing
- Medical: reduces testosterone in prostate cancer
- Medical: suppresses estrogen in endometriosis and uterine fibroids
- Medical: delays precocious puberty
