Deca-Durabolin or nandrolone is arguably the second most well-known injectable steroid after testosterone. This anabolic compound is considered to be one of the best drugs for maintaining lean muscle mass and stimulating appetite.

Nandrolone Decanoate is an injectable form of Nandrolone.The decanoate ester provides a slow release of nandrolone from the injection site, lasting up to three weeks. Nandrolone is very similar to testosterone in structure, although it lacks a carbon atom at the 19th position (hence its other name, 19nortestosterone). Like testosterone, nandrolone exhibits relatively strong anabolic properties. However, unlike testosterone, its tissue-forming activity is accompanied by poor androgenic properties. Much of this has to do with reducing nandrolone to a weaker steroid, dihydronandrolone, in the same androgen-sensitive target tissues that potentiate the action of testosterone (by converting it to DHT). The mild properties of nandrolone decanoate have made it one of the most popular injectable steroids in the world, highly favored by athletes for its ability to promote significant strength and lean muscle mass gains without androgenic or estrogenic side effects. Nandrolone decanoate causes a sharp increase in the release of nandrolone 24 to 48 hours after deep intramuscular injection, which steadily decreases to its baseline about two weeks later. The mean depot-release half-life of nandrolone decanoate is 8 days.

Side effects

Nandrolone has a low tendency to convert estrogen, estimated to be only about 200% of that seen with testosterone. This is because while the liver can convert nandrolone to estradiol, other more active steroid aromatization sites such as nandrolone adipose tissue is much less open to this process. However, high estrogen levels can still be noticed with a higher dose and can cause side effects like increased water retention, body fat gain, and gynecomastia. An anti-estrogen such as clomiphene citrate or tamoxifen citrate may be needed to prevent estrogenic side effects if they occur. Many 19-nor anabolic steroids have shown some affinity for the progesterone receptor as well. The side effects associated with progesterone are similar to those of estrogen.

Dosage and administration

The usual dosage for physical or performance enhancing purposes is the range of 200 to 600 mg per week, taken in cycles 8 to 12 weeks in length. This level is enough for most users to notice measurable gains in lean muscle mass and strength.
