Andarine is one of the most commonly used doping substance between selective androgen receptor modulators (SARMs). The purpose of our study is to characterize qualitatively and quantitatively andarine capsules purchased legally via the Internet through a rapid and precise UHPLC method and the uniformity of mass, content and dissolution assays were determined following the methodology of the European Pharmacopoeia 8th Ed. Regarding the uniformity of mass, the capsules are within the permissible limits, but regarding the active substance content, an average of 4.99 mg of andarine/capsule was obtained (with an RSD of 5.41%) from the 25 mg/capsule declared by the manufacturer.
