Masteron acts like DHT, as it is a derivative. Masteron is most efficient during a cutting cycle. However, for the effects to be truly appreciated the individual will need to be extremely lean. Drostanolone does not cause water retention and has a moderate diuretic effect similarly to stanozolol; this allows improving muscles density, relief and definition. A Masteron cycle can reduce body fat by 5-7%. Drostanolone is recommended for track and field athletes and bodybuilders who want to stay within their particular weight class.
