Clomiphene vs Enclomiphene: side-by-side comparison

SERM

Clomid · Clomiphene Citrate · Serophene

A first-generation SERM that is a mixture of two isomers: 62% enclomiphene (trans, antagonist) and 38% zuclomiphene (cis, agonist). Works primarily at the hypothalamus to block estrogen negative feedback, increasing GnRH pulsatility and subsequent LH/FSH release. Produces a stronger initial LH/FSH spike than tamoxifen but with more side effects, particularly vision issues.

VS
SERM

Androxal · EnCyzix

A SERM that boosts natural testosterone without suppressing fertility. The trans-isomer of clomiphene, it stimulates LH and FSH production more effectively with fewer side effects than Clomid.

Shared goals carry both dots; a goal with one dot belongs to that side alone.

ClomipheneEnclomiphene
PCTHealth

Run for

Post Cycle Therapy (PCT)Stimulates natural testosterone production after steroid cycles. Produces stronger initial LH/FSH spike than tamoxifen.
Male Hypogonadism TreatmentAlternative to TRT that maintains fertility. About 88% of hypogonadal men maintain eugonadal testosterone on long-term clomiphene (studies of >3 years).
Fertility RestorationRestores spermatogenesis in men with steroid-induced azoospermia. Meta-analysis shows a mean sperm-concentration increase of ~8.4 million/mL during treatment.
Testosterone BoostingMeta-analysis shows clomiphene increases total testosterone by approximately 274 ng/dL vs placebo.

Documented upside

  • Stronger initial LH/FSH spike than tamoxifen
  • Preserves and restores fertility (unlike TRT)
  • Maintains intratesticular testosterone for spermatogenesis
  • Well-established use since 1960s
  • Can be used long-term for hypogonadism

Run for

PCTStimulates natural testosterone recovery after suppressive compounds.
Natural Testosterone BoostCan be used standalone to boost testosterone in hypogonadal men while preserving fertility.
Fertility PreservationUnlike TRT, maintains or improves sperm production.

Documented upside

  • Stimulates natural testosterone production
  • Preserves/improves fertility
  • Fewer side effects than Clomid
  • Effective for PCT
  • Can raise testosterone significantly

Clomiphene

Clomiphene IS a PCT drug. Standard protocol: 50/50/25/25 (mg/day for 4 weeks). Can be combined with Nolvadex for enhanced recovery. Start 3-5 days after last oral steroid, or 2-3 weeks after last long-ester injection.

Enclomiphene

This IS a PCT compound. No additional PCT needed after use.

Read-out

How they separate

  1. 01

    Enhancement

    They land at almost the same point on the natty scale (2/10 vs 2/10): a similar distance beyond natural.

  2. 02

    Side-effect bill

    Clomiphene's documented side-effect severity is heavier (2.5/5 vs 2/5). The body-load fingerprint above shows where that weight actually lands.

  3. 03

    Body load

    The widest gap at typical protocols is blood thickness (Enclomiphene 3.5/10 vs 0/10), then mood & sleep (Clomiphene 4.4/10 vs 2.2/10).

  4. 04

    Coming off

    Neither requires PCT: both leave the natural testosterone axis running.

  5. 05

    Logistics

    typical runs are 4-6 weeks vs 4-8 weeks.

  6. 06

    Tested athletes

    Both are WADA-prohibited: neither belongs anywhere near tested competition.
