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.
Triclocarban bioaccumulation is possible in a number of organisms. Earthworms are known to store this chemical in their bodies and, because of their ecological role as a food source, they have the potential to move triclocarban up the food chain.  Microbial species found in soils also bioaccumulate triclocarban. However, the health of these microbes has not been found to be affected by the presence of the chemical.  Triclocarban is rapidly accumulated in both algae and adult caged snails.  Moreover, triclocarban is more likely than triclosan to bioaccumulate in aquatic organisms. 
Antiandrogens like spironolactone are male-specific teratogens which can feminize male fetuses due to their antiandrogen effects (see below ).    For this reason, it is recommended that antiandrogens only be used to treat women who are of reproductive age in conjunction with adequate contraception.    Oral contraceptives, which contain an estrogen and a progestin , are typically used for this purpose.  Moreover, oral contraceptives themselves are functional antiandrogens and are independently effective in the treatment of androgen-dependent skin and hair conditions, and hence can significantly augment the effectiveness of antiandrogens in the treatment of such conditions.
