According to researchers, “In older men, enclomiphene could be used as monotherapy, particularly if the risks of [Testosterone Replacement Therapy] are deemed too high for specific patients.”
​
They are fundamentally different approaches—even if fertility is not a concern, most older men prefer not to experience the testicular shrinkage associated with TRT or the discontinuation syndrome if they stop taking it, even temporarily.
​
With enclomiphene there is no dependence since it stimulates your own natural testosterone production, so you will not feel down if you miss a day or need to take a break/travel.
