The preservative benzyl alcohol has been associated with serious adverse events, including the "gasping syndrome", and death in pediatric patients. Although normal therapeutic doses of this product ordinarily deliver amounts of benzyl alcohol that are substantially lower than those reported in association with the "gasping syndrome", the minimum amount of benzyl alcohol at which toxicity may occur is not known. The risk of benzyl alcohol toxicity depends on the quantity administered and the liver and kidneys’ capacity to detoxify the chemical. Premature and low-birth weight infants may be more likely to develop toxicity.
An effective dosage of Sustanon ranges from 250mg a week to 1000mg per week. Although Sustanon remains active in the body for approximately three weeks, injections are taken at least every 10 days. Sustanon stacks extremely well with potent orals like Anadrol and Anabol , but it might work better with Trenbolone or Winstrol if the athlete is seeking to maintain a harder, more defined look to his physique. Many individuals like to use a combination of Nolvadex & Proviron , while others use an anti-aromatase like Arimidex , Femara, or Aromasin, to help control estrogen related effects. The main side effects of Sustanon are: headache, depression, aggression, anxiety, sleep disorders, numbness, acne, aggressiveness, sexual overstimulation, oily skin, accelerated hair loss, and reduced production of the body's own hormones, nausea, cholestatic jaundice and possible liver damage.
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.
