In bodybuilding, Nandrolone undecanoate is often used for mass build-up, as it has a strong anabolic and moderate androgenic effect. Due to the severe impairment of the body’s testosterone production, it is frequently injected with testosterone. Compared to nandrolone decanoate, the price and the need for frequent injections is a crucial drawback. For beginners and women the number of necessary injections is still within the scope. Professional Bodybuilders dont use Nandrolone Undecanoate, since noone wants to make several injections in one day.
Nandrolone undecanoate is one of the steroids that is also used by women.
Acne, headache, increased blood pressure, nasal bleeding, prolonged blood clotting, increased sebaceous gland production, sexual overstimulation (initially), sexual inactivity (later), inhibition of spermatogenesis, gynecomastia, severe suppression of self-hormone production, water storage, “Deca Dick”
Important: Gynaecomastia, suppression of self-hormone production and increased water retention is triggered more by progesterone than by estrogen. This effect, which originates from nandrolone decanoate, can therefore hardly be counteracted with anti-estrogens
Nandrolone undecanoate can still be detected up to 1.5 years after discontinuation.
