Deca, as this compound is commonly called – due to the decanoate ester attached, is a very effective compound with many benefits to muscle building and few side effects. Nandrolone is not known to cause many estrogen related side-effects although, as is the case with most AAS, this varies substantially from user to user. In general, nandrolone has a low rate of aromatization and does not convert to DHT. Combined, these facts make nandrolone a good choice for anyone concerned about androgen related sides like oily skin, male pattern baldness and enlarged prostate. Nandrolone also seems to exhibit a very positive effect on nitrogen balance, bone mineral and collegen synthesis and is a very good stimulator of appetite. Nandrolone enjoys a very positive reputation for helping to alleviate joint pain.
