Enclomiphene (Enclomiphene Citrate)

Category: Hormone Replacement. Status: Investigational drug.

A selective estrogen receptor modulator (SERM) and the trans-isomer of clomiphene. Widely prescribed by telemedicine clinics as a testosterone optimization therapy that maintains fertility, unlike exogenous testosterone.

How it works

Blocks estrogen receptors in the hypothalamus, reducing negative feedback and increasing GnRH pulsatility, which stimulates LH and FSH release for endogenous testosterone production.

Key facts

  • Molecular weight: 598.09 Da
  • Half-life: 10-14 hours
  • Bioavailability: ~50% oral
  • Storage: Room temperature, protect from moisture.

Dosing overview

  • Typical dose: 12.5-25 mg
  • Frequency: Daily
  • Duration: Ongoing or cycled 8-12 weeks
  • Route: Oral capsule

Protocol notes

  • Most start at 12.5 mg daily and adjust based on follow-up bloodwork (testosterone, LH, FSH, estradiol).
  • 25 mg daily is a common maintenance dose; higher is rarely needed and raises side-effect risk.
  • Used either continuously for testosterone optimization or as a post-cycle/restart protocol for 8-12 weeks.

Reported benefits

  • Increased endogenous testosterone
  • Preserved fertility
  • Improved libido
  • Enhanced energy and mood
  • No testicular atrophy

Possible side effects

  • Headache
  • Mood changes
  • Visual disturbances (rare)
  • Hot flashes
  • Acne

Research

  • Enclomiphene for male hypogonadism (2022): Increased testosterone to eugonadal levels in 86% of men while maintaining sperm counts above baseline.
  • Enclomiphene vs TRT comparison study (2021): Achieved comparable testosterone levels to TRT with preserved gonadotropin levels and spermatogenesis.

Community reviews of Enclomiphene

Rated 4.6 out of 5 from 8 community reviews by ResearchSafe members.

  • cold_chain_carl rated it 5/5 - Worth adding to the protocol: Enclomiphene has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
  • research_marcus rated it 5/5 - Genuinely effective after 2 weeks: Been using Enclomiphene for about 2 weeks and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • wellness_wade rated it 5/5 - Noticed clear benefits within weeks: Added Enclomiphene to my protocol about 1 month ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
  • n_of_one rated it 5/5 - Consistent improvement over 3 weeks: Added Enclomiphene to my protocol about 3 weeks ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
  • fasted_frank rated it 4/5 - Solid compound with real results: Been using Enclomiphene for about 6 weeks and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
  • frugal_chemist rated it 5/5 - Better than my old clomid experiment: 5 stars. I ran enclomiphene for about 3 weeks while still teaching yoga and doing my usual training here in the Philippines, and for me it felt cleaner than the clomid I tried before. My drive came back faster, mornings felt less flat, and I was less cranky with people, which matters when you are coaching classes back to back, ma'am/sir. Could be just my own experience, but I preferred this by a mile.
