Enclomiphene

Trans-isomer of Clomiphene. Stimulates LH/FSH for HPTA recovery without the estrogenic side effects of zuclomiphene (the cis-isomer).

Overview

SERM

Trans-isomer of Clomiphene. Stimulates LH/FSH for HPTA recovery without the estrogenic side effects of zuclomiphene (the cis-isomer).

Effects on Markers

Stimulates LH/FSH (HPTA recovery), raises endogenous testosterone, significantly fewer estrogen-related side effects than Clomiphene (no vision disturbances, less mood impact), does not significantly worsen lipids

Compound Guide

Mechanism: Pure estrogen antagonist at the hypothalamus/pituitary. Unlike Clomiphene (Clomid) which is a 60:40 mix of enclomiphene:zuclomiphene, enclomiphene alone provides SERM activity without zuclomiphene's estrogenic agonist effects.

Dosage:

  • HPTA restart / PCT: 12.5-25mg/day for 4-8 weeks
  • Ongoing HPTA support: 6.25-12.5mg/day (some use low-dose long-term)
  • Fertility support: 12.5-25mg/day until sperm parameters recover

Administration:

  • Oral capsule/tablet, once daily in the morning
  • Can be run longer than traditional PCT SERMs due to cleaner side effect profile

Key Notes:

  • Preferred over Clomiphene (Clomid) by many — same LH/FSH stimulation without zuclomiphene's estrogenic sides
  • No vision disturbances (a known Clomid side effect from zuclomiphene)
  • Raises LH, FSH, and testosterone effectively — good PCT option alongside Tamoxifen
  • Some users run low-dose enclomiphene as a "testosterone optimisation" alternative to TRT
  • Available as a compounded medication in many countries (not widely available as a branded pharmaceutical yet)
  • Monitor: LH, FSH, total/free testosterone, E2 during PCT
