Enclomiphene vs TRT: Which to Consider First Quick Answer Enclomiphene is generally worth trying first for most men, especially if you're younger or care about fertility preservation. Why Consider Enclomiphene First How it works: Stimulates your body to produce its own testosterone naturally (preserves the HPG axis) Key advantages: Maintains fertility and testicular size Reversible - your system isn't suppressed Lower long-term commitment Fewer side effects for many men Good brands/sources: Prescribed through clinics like Marek Health, Defy Medical, or Maximus (their "King" protocol) When TRT Makes More Sense Primary hypogonadism (testes aren't responding) You've tried enclomiphene without adequate response Older age with very low baseline testosterone Don't have fertility concerns Reputable TRT providers: Defy Medical, Marek Health, Fountain TRT, Evolve Telemed Important Considerations Get proper labs first (total T, free T, LH, FSH, estradiol) Work with an actual men's health specialist, not a "T mill" Enclomiphene works best when the issue is secondary hypogonadism Would you like help understanding which labs to get first?
