Our Program


 Our research proves that for optimal efficacy and outcome, DHEA must be taken as a nutritional support at precise, individually tailored doses.



DHEA is a steroidal pro-hormone, naturally produced from cholesterol. DHEA synthesized in the brain functions as a neurosteroid.

Effect of DHEA on drug abuse


Research has shown that a program which includes DHEA administration as a component is beneficial in the treatment of addiction.
