Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Particpants will be randomly allocated to one of four treatment groups.
Group 1 will receive daily subcutaneous (s/c) injections of saline (placebo) for 4 days.
Group 2 will receive daily s/c injections of superactive GnRH analog (Lucrin 1mg) for 4 days.
Group 3 will receive daily s/c injections of Lucrin 1mg for 4 days and concurrent administration of 100mg injectable testosterone (T) esters to supress endogenous leutenising hormone (LH) and T production.
Group 4 will receive daily s/c injections of Lucrin 1mg for 4 days and concurrent administration of nandrolone decanoate 100mg to supress endogenous LH and T production.
Blood and urine samples will be collected from all particpants at intervals from 0 for up to 14 days.
Intervention code [1] 4321 0
Treatment: Drugs
Comparator / control treatment
Group 1 (placebo group) will receive s/c saline injection in place of s/c Lucrin.
All particpants will provide baseline blood and urine samples to measure against post treatment samples.
Control group
Placebo

Outcomes
Primary outcome [1] 5705 0
To determine the hormonal effects of a supercative GnRH analog on the hormonal markers used in sports doping ie serum and urine LH and testosterone, and on the urinary testosterone/epitestosterone (T/E) ratio.
Timepoint [1] 5705 0
Samples of blood and urine will be collected at baseline and daily for up to 14 days.
Secondary outcome [1] 241620 0
To develop a detection test for this GnRH analog to be used in sports doping laboratories.
Timepoint [1] 241620 0
GnRH analog detection test will be developed following the collection of all study samples.
