    Product Description

    Levonorgestrel-d6 is intended for use as an internal standard for the quantification of levonorgestrel (Item No. 10006318) by GC- or LC-MS. Levonorgestrel is a synthetic progestin and the biologically active component of norgestrel (Item No. 10006319).1 In vivo, levonorgestrel (60 μg/day) suppresses estrus and pregnancy in female cats.2 Post-coital insertion of subdermal levonorgestrel (5 mg pellet) implants prevents uterine implantation of embryos in mice.3 Formulations containing levonorgestrel have been used as contraceptives.

    WARNING This product is not for human or veterinary use.
