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.
