    TLDR The document concludes that better biomarkers are needed to detect long-term oral testosterone use in athletes.
    The document from July 2006 discusses the use of anabolic-androgenic steroids, specifically testosterone, in sports and the methods employed by anti-doping laboratories to detect them in urine. Anabolic steroids, which are banned substances in sports, can be difficult to differentiate from natural testosterone using gas chromatography-mass spectrometry. The paper outlines indirect detection methods, such as the testosterone/epitestosterone glucuronide ratio, and direct methods like carbon isotope ratio determination. The World Anti-Doping Agency provided guidelines in August 2004 for reporting abnormal urinary steroid profiles indicative of testosterone or its precursors' administration. The technology for detecting testosterone is effective for intramuscularly administered testosterone, but oral administration requires urine samples to be collected shortly after intake due to rapid pharmacokinetics. The paper concludes that there is a need for specific biomarkers to detect long-term oral testosterone administration.

      in Minoxidil  5 upvotes 7 months ago
      The user started using trenbolone and minoxidil simultaneously and experienced increased hair shedding, unsure which is causing it. Replies suggest both drugs could cause hair loss, with one advising to stop trenbolone to protect hair and another indicating minoxidil is unlikely the cause due to the timing.

      A user shared a 15-year experience using minoxidil and finasteride for hair loss, stating that despite never missing a dose, their hairline continued to recede slowly. Other users suggested that the hair loss might be exacerbated by the use of steroids and recommended considering other treatments like dutasteride and RU58841.

      The conversation discusses hair loss treatments, focusing on the use of topical minoxidil, microneedling, finasteride, and dutasteride, while debating the role of testosterone and DHT in hair loss. It also touches on the potential liver health impacts of these treatments and the genetic sensitivity of hair follicles to androgens.
