Oral dianabol may also be effective as it can clear away quickly from the body. Also, during the whole cycle, efforts should be made to keep the levels of estrogen down. This can be done with the help of compounds like formestane and arimidex . Taking non-aromatizable steroids like winstrol and trenbolone is also a good way to keep estrogen levels under control.
