Anabolic steroid implants are allowed for veterinary use. But if someone diverts this for use in humans, it will be deemed as a distribution of a Schedule III drug leading to prosecution. The law on trenbolone differs in other countries. For instance, in Canada it is a Schedule IV drug. In Canada, all anabolic steroids are classified as Schedule IV drugs. In the UK, anabolic steroids are classified as Class C substances. Their possession can lead to a 2 year jail term, while their production and supply can lead to a 14 year jail term. But many countries do not have strict laws. In some places, you can even buy it over the counter.
In normal tissue, DIM (300nM) can activate the ATM genetic repair pathway in response to irradiation damage in a manner dependent on BRCA1 (one of its targets  ) without increasing survival of breast cancer cells (MDA-MB-231  ); there are known alterations in this pathway in some breast cancers where BRCA1 is reduced while ATM itself seems to be hyperactive, and oral supplementation of 300mg DIM has been noted to increase BRCA1 mRNA levels after 4-6 weeks supplementation (measured in white blood cells) in women who had a low activity mutation.
