For instance, most progestin based steroids such as nandrolone, trenbolone and dienedione (TREN) are unnatural and lack the ability to convert to DHT. Other popular unnatural steroids such as methyldrostanolone (Superdrol), methylepitiostanol (Epistane) also lack the ability to convert to DHT. Guess what? All these steroids are known to be associated with libido and gyno issues.
Users will typically revert to a steroidal anti-estrogen to lower estrogen in an attempt to stop the gyno or raise the libido. However, this can worsen the situation by further suppressing DHT since steroidial anti-estrogens (6-oxo, ATD and formestane) cant convert to DHT and actually lower DHT levels by blocking other hormones from converting to DHT (by hogging the 5a-reductase enzyme).
