Facts: Deca-Durabolin is the brand name for an injectable steroid originally produced by Organon in 1962. It contains the active hormone Nandrolone with the Decanoate ester. The Nandrolone hormone is highly anabolic and produces very few side effects when used in reasonable doses; the Decanoate ester is a fatty acid which slows its release into the body over several weeks.
Nandrolone is technically a derivative of testosterone but it is created by removing the carbon atom at the 19th position of the steran nucleus, which creates a completely different family of steroids (the 19nor-testosterone family). It is one of the most versatile steroids on the market today, and can be used successfully in both bulking and cutting cycles, while in the clinical setting it has been used effectively to treat muscle wasting associated with HIV and AIDS.
Deca-Durabolin doesn’t produce many estrogenic side effects due to its low rate of aromatization (metabolic conversion to estrogen via the aromatase enzyme). Its ability to improve collagen synthesis and bone mineral content (1) is highly prized by bodybuilders and athletes who may have nagging injuries or joint pains.
But it’s not just Deca’s healing attributes which have made it such a popular steroid; bodybuilders and athletes have found Deca-Durabolin to be one of the best all-around steroids for gaining lean mass, and we see this played out in various clinical studies also (2)(3)(4). Muscle gained with this product is very solid with minimal bloat, as long as dosages are kept reasonable.
Because Deca-Durabolin is so popular, I thought that it’s important to note that it is considered a very long acting steroid, but the research is very inconsistent regarding just how long lasting it is. In healthy, normal, men one study found an average half-life of 8 days (but the range was from 5 to 17 days) at a dose of 50 mg (5), while another study found an average half-life of 5.9 days at a dose of 200 mg (6), another found an average of 7.7 days at a dose of 100 mg (7), and a final study I looked at showed an average of 7.1, 11.7, and 11.8 days depending heavily on the dose being either 50 mg, 100mg, or 150 mg, respectively (8).
In a practical sense, people will still shoot Deca once a week, but I thought it was important to show that typical half-life charts don’t factor in every single dose or dose response.
And, to further complicate things, the milligram per milliliter concentration and location of injection site heavily determines the actual blood plasma concentration achieved by a single shot of Nandrolone Decanoate (9): gluteal shots of Nandrolone Decanoate give you higher blood plasma levels of the parent hormone, and more highly concentrated preperations (mg/ml) also give you a higher overall blood level – and will probably provide better results, all things being equal.
Practical Use: Deca-Durabolin is easily the most versatile anabolic steroid on the market today (testosterone just misses that mark by virtue of the fact that women need to avoid it). It can be used in cutting cycles as well as bulking cycles, depending on the other compounds (and diet) one chooses.
Deca Duaraoblin Side Effects: Deca is one of the most mild steroids on the market in terms of side effects. Men who are very prone to hair loss will sometimes experience this with Deca-Durabolin, and gynecomastia is possible with higher doses. The most common side effect experienced with Deca-Durabolin is sexual dysfunction, although most users simply stack it with testosterone and avoid this entirely.
Used By: Because it’s so versatile, Deca-Durabolin is used by athletes, bodybuilders, and powerlifters alike. Women have found it to be mild enough to use at low doses, and many champion physiques of both genders have been built with its use. The only people who would be well advised to avoid Deca are drug tested athletes, as Nandrolone metabolites are detectable in urine for up to 18 months after the last injection.
Deca Durabolin Dosage: For men, an average dose of Deca-Durabolin is in the range of 200-600 milligrams. In women, 50 milligrams is a much more reasonable dose, although I have seen women go up to 100 milligrams without experiencing intolerable side effects.
Deca Duraboline Cycle: Deca-Durabolin works well with virtually every steroid. A good cutting cycle could include Deca, Winstrol, and testosterone – while a good bulking cycle could include Deca, Testosterone, and Anadrol.
