The average Trenbolone Acetate dose varies based on your cycle and stack. During an off-season bulking cycle, most bodybuilders find that 50mg every other day is comfortable and effective. Some men tolerate up to 100mg every other day with no issues, and they find that this does offers the best results for them. During a cutting cycle, people tend to push the envelope a little more with Tren and utilize doses even higher than 100mg every other day, but not everyone can tolerate these as the risk of side effects increases. No one should ever use more than 200mg every other day, even if they seem to tolerate it well.
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.
As a bulking agent, the effects of Masteron will prove to be rather weak. It is possible the hormone could provide gains in mass similar to Primobolan (which wouldn't be that strong either) if the total dose was sufficiently high. However, the relative gain in size will be moderate with many anabolic steroids being far more suited for this period of steroidal supplementation. Masteron does not aromatize and is not estrogenic; in fact, it shows anti-estrogenic traits in the body and binds to aromatase instead of other substrates. This is why it has been effective in the treatment of breast cancer.
