Deca-Durabolin is the brand and trade name of the anabolic steroid nandrolone. Specifically, Deca-Durabolin is the trade name for nandrolone decanoate, a variation of the nandrolone decanoate ester.
“Deca” is the unofficial name for the drug in the bodybuilding world, one of the top three anabolic steroids and the second most popular and widely used anabolic steroid in existence. The first is none other than Dianabol (Methandrostenolone), the third is Winstrol (Stanozolol). There’s a good reason why Deca-Durabolin is so popular among bodybuilders and athletes, and is even held in high regard by the medical establishment.
Nandrolone Decanoate is one of the earliest developments in the field of anabolic steroids, introduced to the scientific community in 1960 and launched on the prescription drug market a few years later in 1962 as Deca-Durabolin. The drug was developed by Organon.
At the same time, few people know that as early as 1957 nandrolone existed as a variant of the fast-acting ester – nandrolone phenylpropionate – which gained great popularity. However, due to its short half-life (requiring at least daily injections), its use was limited. As a result, nandrolone was reinvented as Deca-Durabolin with a decanoate ester attached to it. For this reason, Nandrolone Decanoate has a longer half-life of around 15 days, while Nandrolone Phenylpropionate has a half-life of around 4 days.
Over time, the drug has been widely used as a medicine by medical institutions, and has also gained popularity among athletes due to its supposedly “mild” nature. There is some truth to this, but there are myths and misconceptions which we will discuss below.
The anabolic rating of testosterone is 100 while that of deca is 125, which means that deca is slightly stronger than testosterone. However, Deca has a low androgenic rating of 37, which is beneficial for people who are hypersensitive to androgenic side effects. Additionally, nandrolone has very little estrogenic activity and binds very poorly to the aromatase enzyme responsible for converting androgens to estrogen. Only about 20% of nandrolone converts to estrogen compared to testosterone, and that’s because Deca is a progestogen (like all 19-nortestosterone compounds).
Deca is classified as a 19-nortestosterone compound due to the lack of carbon at position 19 (which testosterone has), which makes it a progestogen. This can introduce potential side effects and issues that are unique to 19-nortestosterone compounds and unseen by most other anabolic steroids.
As mentioned earlier, Deca is often referred to as a very “mild” anabolic steroid compared to other compounds when it comes to side effects. Unfortunately, this is a mix of fact and fiction that needs to be taken into account, and most claims that “deca is a mild steroid” come from a time when little was known. on these drugs. Deca-Durabolin is obviously a mild and harsh anabolic steroid that has both properties.
The good news is that Deca-Durabolin has very low estrogen aromatization, which makes estrogenic side effects less of a problem compared to other anabolic steroids. However, users should understand that estrogenic side effects will not disappear completely but will become more manageable. Manifestations of side effects include bloating, fluid retention, increased blood pressure due to fluid retention, and gynecomastia.
All problems related to progesterone and prolactin can manifest as puffy nipples, gynecomastia, bloating, etc. Anti-estrogens and aromatase inhibitors are known to be effective in combating these side effects. For example Arimidex which is the brand name of Anastrozole or Clomid which is also known as Clostilbegit. Cabergoline and bromocriptine are also very effective in lowering high prolactin levels and are often the first line of treatment for this.
Nandrolone is not a C17-alpha-alkylated (C17-aa) oral anabolic steroid and therefore has no effect on the liver. Deca shows a low level of androgenic effects that still need to be monitored and considered. Androgenic side effects may include increased acne, oily skin, increased body and facial hair growth, increased risk of male pattern baldness, and increased risk of benign prostatic hyperplasia.
Nandrolone suppresses endogenous testosterone. When used alone, 100mg of nandrolone can cause a complete shutdown of the natural anabolic hormone, so it’s very important to use nandrolone in combination with testosterone enanthate or testosterone cypionate or, corny , with testosterone blends. This ensures that there is no risk of cutting off and suppressing endogenous testosterone supply. After completing the course, a PCT (recovery after a course of steroids) is mandatory. However, remember that it takes time to restore the body to its natural state. If you do not fully understand the basic principles of taking anabolic steroids, you can cause enormous damage to the body, which may be irreversible.
As far as the liver is concerned, nandrolone is not hepatotoxic.
Cycle and application
Of course bodybuilders and other athletes use Deca-Durabolin to increase volume, mass and strength. This is partly due to its positive and beneficial effects on connective tissue and bone tissue, which provide a faster healing rate and additional injury prevention with the use of more weight and more intense physical activity.
Since Deca-Durabolin is a long-acting ester variant of nandrolone (with a half-life of 15 days), Deca-Durabolin cycles should be at least 12 weeks long. Here it is often combined with long ester analogues such as Testosterone Cypionate. Due to its long-lasting nature, most users won’t feel it “turn on,” at least not for the first few weeks of the cycle. And in this period, many people associate additional drugs with the Deca-Durabolin cycle for overclocking. This is usually any oral anabolic steroid such as Dianabol, Winstrol, Anadrol, Turinabol etc. However, to increase volume and strength most people gravitate towards drugs that are normally suitable for these purposes such as Anadrol (oxymetholone) or Dianabol (methandrostenolone) , during the first 4-6 weeks. These compounds are used for their bulking properties, which lend themselves very well to Deca-Durabolin and Testosterone.
The typical cycle combination is often discussed here – testosterone/deca/dianabol. Simply put, this is the most popular loop stack of all time. This combination was originally invented and popularized by the bodybuilders of the golden era of the 1960’s and 1970’s. Recommended for all levels of users (beginners, intermediate and professionals) as it is versatile to offer a quality boost to any user, regardless of experience.
