17β-Nandrolone-d3

17β-Nandrolone-d3 is a synthetic anabolic steroid that belongs to the class of 19-nortestosterone derivatives. It is a deuterated form of the naturally occurring hormone nandrolone, which is produced in the body by the adrenal glands and gonads. This compound is commonly used by athletes and bodybuilders to increase muscle mass, strength, and endurance. It is also used medically to treat osteoporosis, anemia, and wasting syndrome in patients with HIV/AIDS. The mechanism of action of 17β-Nandrolone-d3 is similar to that of other anabolic steroids. It binds to androgen receptors in muscle cells, which stimulates protein synthesis and muscle growth. It also increases the production of red blood cells, which enhances oxygen delivery to the muscles, improving endurance and reducing fatigue. In terms of chemical information, 17β-Nandrolone-d3 has a molecular formula of C18H26D3O2, and a molecular weight of 286.45 g/mol. It has a half-life of approximately 6-8 days, which means it stays active in the body for a relatively long period of time. This compound is often administered via injection, typically in a dosage range of 200-400mg per week for men and 50-100mg per week for women. Like other anabolic steroids, 17β-Nandrolone-d3 can cause side effects such as acne, hair loss, and increased body hair growth. It can also suppress natural testosterone production, leading to testicular atrophy and decreased libido. Therefore, it is important to use this compound under medical supervision and to adhere to recommended dosages and cycle lengths.
