From this mixture of four different testosterones we receive a steady dose of testosterone at different times keeping the level of active testosterone in the body stable. There are many varying opinions as to if a blend of testosterones such as that of Sustanon is needed and as is with so many things in the anabolic steroid world this is very user dependent. Make no mistake, 250mg of Sustanon versus 250mg of testosterone-enanthate is either way 250mg of testosterone and you can keep your levels of flowing testosterone exactly the same regardless of the type of testosterones you use, however, to do so will depend on your injection frequency.
