There are very few side-effects. Blood clotting time is increased so that some people may experience bloody noses when they are dehydrated. Deca (nandrolone decanoate) is generally considered by athletes and sports medicine physicians to be the safest and most effective injectable anabolic steroid. Nandrolone decanoate is mildly androgenic and is becoming increasingly popular with women bodybuilders. Although side effects similar to those of other steroids have been reported, the effects are relatively uncommon when compared to other forms of steroids. Nandrolone does not effect the immune system, unlike testosterone! It will not damage connective tissue, . elbows, knees (Big problem amongst heavy steroid users). It does not aromatize easily and gives the body a lean hard look.
The most common daily dose of Anapolon is 100mg, but even at that dosage side-effects like water-retention, elevated blood pressure, acne, hair loss, blood clotting changes, gynocomastia, liver toxicity and mood swings are very often reported. Using aromatase inhibitors to control estrogen aromatization will be ineffective as this drug does not directly convert into estrogen. It was suggested that oxymetholone can activate the estrogen receptor, similar to, but more profoundly than the estrogenic androgen methandriol. Supplements like Milk Thistle can be taken to help keep liver enzyme levels between safe ranges.
