Product Brief

Functionally, this oral product acts as an aromatase inhibitor initially introduced for the advance treatment of hormonally-responsive breast cancers for the post menopausal women. It has been found that certain types of breast cancers grow faster with the intervention of estrogen. This anti-estrogen product helps in decreasing estrogen in the body. This product does not cause water retention and this is another reason why Letroplex is popular with the community of strength sports persons during the post cycle period. Moreover, after a cycle of an anabolic product is complete there is a possibility of estrogen conversion. This product effectively prevents this process so the muscle building process is not hampered.
