While tremendously beneficial to the cutting phase and often considered essential to competitive bodybuilders during contest prep, Trenbolone Acetate is also a phenomenal off-season bulking steroid . When we refer to this hormonal compound as versatile, that is truly an accurate statement. There are very few anabolic steroids that can promote mass like Trenbolone Acetate. More importantly, the effects of Trenbolone Acetate in this regard are not only strong but are far cleaner than most traditional bulking steroids. This hormone will not and cannot promote water retention, meaning each and every pound of weight gained due to use will be lean muscle mass. Of equal importance will be this steroid’s ability to help the individual control fat gain during a period of growth. To achieve true growth, this will require total caloric intake to be slightly above maintenance levels. How far above will vary from one man to the next, and while many often take it too far, this phase will still require a slight surplus. Unfortunately, this necessary surplus will promote body fat gains but due to the metabolic factors that surround Trenbolone Acetate they will be minimized. This is not a license to eat like there’s no end in sight, you can still gain a lot of fat if you continually gorge but you should be able to make better use of your total caloric intake. Those who supplement with Trenbolone Acetate during off-season periods of growth should gain less body fat than they would have without it.
Unfortunately, the same study that tells us that MENT is 10x as anabolic as testosterone, and 4x as androgenic, also tells us that MENT is 12x as suppressive to serum gonadatropins as testosterone. For this reason, it is very appealing to scientists who have studied it for use as a male contraceptive – and ended up calling it “ The Optimal Androgen for Male Contraception ” (Ann Med. 1993 Apr;25(2):199-205.). In addition, and partly owing to its inability to be 5a-reduced, MENT is converted (via the aromatase enzyme) to a very potent form of estrogen – which can cause gynecomastia (enlarged breast tissue in males), and several other nasty side effects.
