600-EŽ contains a powerful anti-androgen which is formulated to shut down the receptors responsible for hair growth activity (the pathway through the T-5 alpha-reductase receptor).
By blocking testosterone from instructing cellular proliferation and mitosis during a critical developmental stage, the entire growth phase (anagen) can be prevented.

This formula has shown substantial efficacy on secondary and post-secondary hair growth types (hair which emerges from the body following puberty between the ages of 18 and 38 years). Unlike other anti-androgens, cimetidine has not shown adverse reactions in female subjects or fetal impairment (such as what has been reported with the use of finasteride*). No erectile dysfunction or sexual performance implications have been associated with use.

PSORET 600-EŽ offers a highly localized (site specific) treatment. It may be used to treat hair growth on shoulders but not impact the chest area.
A 100 ml kit will be adequate to treat the average man's chest and abdomen (or the average woman's legs) for 30 days. Recommended dosage is to apply a thin layer (do not massage or rub into the skin) and allow to dry. Apply twice daily for the first 14 days, then once daily thereafter.
