A urine test will detect steroids in a urine sample for up to 28 days. The detection window will vary depending on various factors, like the quantity of steroids consumed and the metabolism of the person tested.

The time it takes for steroids to altogether leave your system ranges from a few days to several months, depending on the steroid type, dosage, and individual metabolism.

Every athlete knows that his/her urine will be tested for drug 1 use when they enter an important competition. To avoid detection of steroids in their urine, athletes will stop using the drugs well before the competition. Yet, in many cases, steroids can still be detected long after the athlete stops using them (even weeks later!).
