Although we say Tren A is excellent for cutting, it is also a very good off-season bulking steroid, and few anabolic steroids have a stronger build muscle ability than Tren A. What's more, the muscle obtained through Tren A was far cleaner than most traditional weight-gaining steroids. Because it does not cause water retention, all the muscle weight gained through it is lean muscle.
Just as importantly, it also helps control fat gain during the weight gain phase. During the weight gain phase, users consume more total calories than they burn in order to achieve muscle mass gain. This caloric surplus, for the most part, translates into fat gain. But the increase in fat was minimized if the anabolic steroid users used during their weight gain was Tren A. This doesn't mean that you can binge on food without fear. If you don't pay attention to your diet at all, you can still gain a lot of fat. Those who supplemented themselves with Tren A during the off-season were likely to gain even less body fat.
Using Tren A can also greatly increase the endurance of your muscles so that they don't tire out as quickly. That's what many anabolic steroids can do, but Trenbolone might be a little more powerful. Through it, muscle endurance and overall recovery speed will improve. This is just as important, because strength gains and quick recovery are the main reasons you're able to last longer in the gym, and it's key to making real progress.
Tren A can improve nutritional efficiency, which may be why they offer it to cattle. Food is the basis of muscle building, however, the body can only use the nutrients it ingests to a certain extent and most of them are wasted. Therefore, the utilization rate of food intake also plays a large role in muscle mass gain. The total amount of food consumed by Tren A for bulking remained the same, but the body made better use of the nutrients to achieve better muscle mass gain.
