The two new dedicated products, Preven and Plan B, are not yet widely available. Plan B is, as of mid-October, newly available for purchase in pharmacies via physician prescription, having previously been distributed only in Title 10 clinics, Planned Parenthood clinics, state and county health departments and university campus health centers. Preven has been available through pharmacies for over a year, but still is not readily available in many locations. Both dedicated products should become more accessible in all locations according to physician demand.
Biomarkers are an important part of clinical drug development; they enable the development of safer drugs with quicker approvals. Steroids are of great interest as biomarkers for various diseases and have been used in clinical and preclinical studies of endocrine disorders. Urinary steroid profiling, can be used to measure a normal biologic process or the response of the body to therapy.

According to Hunter's 2004 testimony before a federal grand jury, Jones's use of banned drugs began well before Sydney.  Hunter told the investigators that Jones first obtained EPO (Erythropoietin) from Graham, who Hunter said had a Mexican connection for the drug. Later, Hunter said, Graham met Conte, who began providing the coach with BALCO "nutritional supplements", which were actually an experimental class of "designer" steroids said to be undetectable by any drug screening procedures available at the time. Graham then distributed the performance enhancers to Jones and other Sprint Capitol athletes. Still later, Hunter told federal agents, Jones began receiving drugs directly from Conte.
