I recently have been putting up post asking question about getting tested for steroids due to a local competition I am doing. I have not used anything in 8-9months but my last cycle included Decca. I know from research Decca is detectable for 18months. I took a Hair test a few days ago and my results are Negative. I am guessing from my results Deca does not stay detectable for 18months unless I would have failed. I didn't use any cleansers, hope this helps some people out there
