I have not been able to find definitive info on how long Clenbuterol actually stays in your system. I have seen claims of 2-4 days and 4-6 days up to months. I used liquid clen for about a month (not every day, a couple days off and on) and I now have a legit steroid test that can detect clen to a 2ng/ml. The test was 15 days after my last consumption of clen. I eat healthy and drink lots of water and exercise daily. Can anyone help me and let me know what im facing? Definite fail or is it out of my system? I appreciate any help that anyone can offer.
