Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.

The side effects of Boldenone Undecylenate are very mild and are visible only when taken in high doses and for a very long period. Among these symptoms we may encounter nausea, leukopenia, symptoms resembling a peptic ulcer, acne, oily skin, hair loss, diarrhea, hypertension, prolonged blood clotting time, increase in libido. Women find Boldenone Undecylenate quite comfortable; virilization symptoms are usually insignificant when taken at low doses. However for more sensible female athletes there are some side effects as: menstrual irregularities, post-menopausal bleeding, increased sex drive, swelling of the breasts, hoarseness or deepening of the voice, and enlargement of the clitoris.

As its production and use increased, public response was mixed. At the same time that DDT was hailed as part of the "world of tomorrow," concerns were expressed about its potential to kill harmless and beneficial insects (particularly pollinators ), birds, fish, and eventually humans. The issue of toxicity was complicated, partly because DDT's effects varied from species to species, and partly because consecutive exposures could accumulate, causing damage comparable to large doses. A number of states attempted to regulate DDT. [6] [12] In the 1950s the federal government began tightening regulations governing its use. [19] These events received little attention. Women like Dorothy Colson and Mamie Ella Plyler of Claxton, Georgia gathered evidence about DDT's effects and wrote to the Georgia Department of Public Health, the National Health Council in New York City, and other organizations.

Boldenone undecylenate (BOL) is an anabolic androgenic steroid used in livestock to improve growth and food conversion. This study investigated the actions of BOL on structure and functions of rabbit liver as well as the effects of its withdrawal. Eighteen mature male New Zealand rabbits were divided into 2 groups: Control group (n=6) were injected with mL corn oil/kg body weight (BW), while BOL group (n=12) received 3 intramuscular injections, 2 wk apart, of BOL ( mg/kg BW). Animals were scarified 1 d after last injection except for 6 rabbits from BOL group that served as the BOL-withdrawal group (4 wk after the 3rd injection). Intramuscular injection of BOL increased ( P <) malondialdehyde (MDA) level, but markedly lowered activities of superoxide dismutase (SOD) and catalase (CAT) and reduced glutathione (GSH) concentration compared to both control and BOL-withdrawal groups. Treatment with BOL significantly ( P <) increased serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) compared to the control group. BOL injection caused different histopathological alterations and apoptosis in liver, but these changes were less evident in the BOL-withdrawal group. Expression of p53 and tumour necrosis factor-α (TNF-α) genes was up regulated in BOL compared to control group, while the expressions of p53 and TNF-α were down regulated in BOL-withdrawal group in comparison with BOL group. In conclusion, BOL injection induced structural and functional changes in the liver of rabbits, increasing oxidative stress and mediators of apoptosis such as ROS, p53 and TNF-α. All these parameters returned to near the control values after withdrawal.
