As others have said no it is not required. That being said I think you would enjoy better results with something like Inhibit-E from SNS or Eclipse from Apex Alchemy. With so many environmental estrogens and phytoestrogens in the food supply, I am of the opinion that many males would benefit from moderate estrogen manipulation. A low to moderate dose of either of the aforementioned products would be perfect for optimizing E levels.
Test boosters, the good ones, suffer from miss marketing IMO. I use them for the increased sense of well-being, increased libido and performance as well as the increased motivation/mood/confidence that many refer to, and I hate this term, an alpha feeling. Of course, the boost in test is still within normal ranges but when you have zero test to begin with, my last three labs were 18ng/dl total 6.1pg/ml free------147ng/dl total---------13ng/dl total you notice even a small increase in a big way. For me feeling is the most important measure of TRT success. I feel as good on M-Test, Alpha Gainz 4-andro(1ML/day), Iconic Formulations DHEA(.5-1.0ML/day) and a natural estrogen product such as the above or letrone/rebirth as I do on 10mg/day Test Cyp with .25mg Adex twice a week and HCG 200iu twice a week.
TLDR: M-Test is not testosterone cypionate in pill form and would be better marketed as a Male Optimizer and quality of life product(as wood all test boosters.) Temper your expectations and you will not be disappointed.
