Are you illiterate or just trolling. Either way -- again.
The detectability level for this study of clostebol was 0,1ng/ml, and they did 3 experiments:
1: female applied CLOSTEBOL cream 3 times over a day to a male; urine samples were collected for 11 days on the male (peak around 30ng/ml, lowest at 11 days 0,8ng/ml) and 6 days on the female (peak around 20ng/ml, lowest at 6 days 0,4ng/ml). Unknown how long the detectability window is because they didn't collect samples anymore, but they suggest it can extend significantly above the tested window.
2: male applied CLOSTEBOL cream to himself once, another volunteer came into contact for a few seconds with the area where the cream was applied, 1h after the application. Male was tested for 6 days (peak 8ng/ml, lowest at 6 days 1,3ng/ml), 2nd volunteer for 2 days (peak 4ng/ml, lowest 0,5ng/ml).
3: female applied herself with CLOSTEBOL cream once, then waited 30 minutes without washing her hands, and shook hands for a few seconds with 7 volunteers. The volunteers were tested only once, 4-5 hours after the contact, and 6 out of 7 tested positive, with values between 0,5ng/ml and 0,1ng/ml.
As for the kynetics, the levels tend to have an early peak, and once they reach 1-2ng/ml it goes very slowly down (on experiment 1, the male volunteer went from 30 to 2ng in 5 days, and from 2ng to 0,8ng in the next 6 days).
Sinner's levels of CLOSTEBOL were 0,086ng/ml and 0,076ng/ml, for reference.
