Pregnenolone is a steroid hormone that is naturally produced in the body and is used to make other hormones such as estrogen and testosterone. However, during the manufacturing process or storage, pregnenolone may become contaminated with impurities or byproducts. These impurities can affect the purity and potency of the pregnenolone product and may cause adverse effects or reactions in the user. Therefore, it is important to ensure that pregnenolone products are tested and certified for purity and quality to minimize the risk of impurities.
