1 hit in the morning 1 at lunch finish the rest off at night pack a new one mabey take 1 or 2 off it before i went to sleep but again it was almost a everyday thing i have been clean now for 29 days and will have a test at 36 days the cut off will be 50ng what are my chances of being clean for that test ?
i have been working out some the past 2 weeks mabey 3 nights out of the week and i upped my intake of water everyday Have i got a shot ? i last tested myself with a home test at 27days With my second Void and failed
