Enclomiphene- Summary
- Spermidine is a naturally occurring polyamine found in all living cells, with exceptionally high concentrations in wheat germ, aged cheese, and human sperm. It is the most studied autophagy-inducing dietary compound, shown to extend lifespan across multiple species and reduce cardiovascular and cognitive aging.
- Enclomiphene is the trans-isomer of clomiphene citrate, a selective estrogen receptor modulator (SERM) that stimulates endogenous testosterone production by blocking estrogen negative feedback on the hypothalamus and pituitary. Unlike TRT, it restores testosterone while preserving or increasing sperm production and testicular volume.
- Half-Life
- ~30–60 minutes, but gut bacteria produce it continuously; supplementation raises tissue levels over weeks
- 5-7 days (long half-life; accumulates)

- Typical Dose
- 1–5 mg
- 12.5-25 mg per day
- Frequency
- Once daily
- Once daily or every other day
- Key Benefits
- Induces autophagy — cellular self-cleaning
- Extends lifespan in yeast, flies, worms, and mice
- Reduces cardiovascular aging and arterial stiffness
- Reduces all-cause mortality (human epidemiological data)
- Neuroprotective: reduces amyloid and tau pathology
- Promotes hair growth (anagen phase activation)
- Reduces age-related immune decline
- Improves memory in aging models
- Restores testosterone to normal range without exogenous androgen administration
- Preserves or increases sperm production and fertility
- Maintains testicular volume (unlike TRT which causes testicular atrophy)
- LH and FSH levels rise, indicating intact HPG axis function
- Option for hypogonadal men desiring fertility
- Oral administration (no injection required)
- Side Effects
- Generally very well tolerated
- Rare: mild GI discomfort at high doses
- May temporarily reduce some gut bacteria species
- Rare: headache at initiation
- Visual disturbances (rare but class-related SERM effect)
- Mood changes or irritability
- Hot flashes
- Elevated estradiol in some users
