Ansomone is a brand of human growth hormone used to treat growth hormone deficiency in children and adults, but is also used off-label for bodybuilding and anti-aging. It is produced with recombinant DNA technology, and benefits include increasing growth in children and improving bone density and muscle mass in adults. Non-medical use of Ansomone is controversial and can lead to negative side effects such as joint pain, swelling, and certain types of cancer. Its use should only be under the guidance of a healthcare professional.
