Sustanon 250 by Organon Karachi - Legit Testosterone Blend Sustanon 250 is an injectable anabolic steroid which represents a blend composed of testosterone propionate (30 mg); testosterone phenylpropionate (60 mg); testosterone isocaproate (60mg); and testosterone decanoate (100 mg). Sustanon is a strong anabolic with pronounced androgenic activity. It is mainly used as a bulking drug, providing good gains in strength and muscle mass. The compound promotes water retention and also has the property to aromatize quite easily. It suppresses natural testosterone production rather quickly and has an active life of approximately 15-21 days. 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.
