Even though you will be supplementing with testosterone as your natural production will have been suppressed your testicles will atrophy with Trenbolone use. This atrophy occurs due to the fact of no testosterone being made and it will cause the testicles to lose some of their fullness. This is however a very temporary effect as the testicles will return to their normal size once use has been discontinued. Once use of all anabolic steroids ends your body will begin producing its own testosterone again and as it does your testicles will regain their normal level of fullness.
