Nandrolone Wikipedia
Nandrolone, also known chemically as 19-nortestosterone (19-NT), is an androgen and anabolic steroid (AAS) similarly to testosterone (T). It is used as a medication by intramuscular or subcutaneous injection in the form of longer-acting esters like nandrolone decanoate (ND; Deca-Durabolin) http://explicitclick.com/2024/12/igf1-lr3-1mg-peptide-sciences-7/ and nandrolone phenylpropionate (NPP; Durabolin), which are converted into nandrolone in the body. This is analogous to longer-acting testosterone esters like testosterone enanthate (TE) and testosterone undecanoate (TU) and their conversion in the body into testosterone. Nandrolone is used in medicine for a variety of indications that benefit from anabolic effects in tissues like muscle, bone, and kidneys.

In this context, nandrolone acts as an androgen receptor agonist that is not converted endogenously to DHT (15). As such, it provides negative feedback to the HPG axis to suppresses testosterone levels, further decreasing the available testosterone and DHT, compounding its negative effects on erectile function. Recent studies in animal models have identified a potential role for nandrolone in joint pain, particularly post rotator cuff tears (31,32). In one such study by Gerber et al. (31), 20 New Zealand white rabbits had their supraspinatus tendon released with musculotendinous retraction and observed over 6 weeks. Rabbits were organized into groups treated with placebo as well as local and systemic administration of nandrolone (31). Nandrolone, given in the phase after tendon release, was found to inhibit fatty infiltration of the supraspinatus muscle and reduced functional impairment of the rotator cuff (31).
In addition, androgens oppose the effects of estrogens in the breasts, and may inhibit breast development even with low-level exposure or physiological levels in females (Dimitrakakis et al., 2003; Peters et al., 2011; Sas et al., 2014; Barbieri, 2017). Certain clinical effects and adverse reactions demonstrate the androgenic properties of this class of drugs. Complete dissociation of anabolic and androgenic effects has not been achieved. The actions of anabolic steroids are therefore similar to those of male sex hormones with the possibility of causing serious disturbances of growth and sexual development if given to young children. Anabolic steroids suppress the gonadotropic functions of the pituitary and may exert a direct effect upon the testis.

- Its consumption can trigger a series of adverse side effects in the body, both acute and chronic 18.
- It is imperative that you know and understand the law of where you live before you make a purchase of Nandrolone or any anabolic steroid.
- It is essential to follow a healthcare provider’s instructions regarding dosage and frequency.
- From there, there are have been a number of different kinds of Nandrolone that have floated around, but Deca Durabolin is king as far as popular brands go.
Similar skin characteristics were highlighted in another case report by Tripathi and colleagues, of a 55-year-old woman 82. Self-injection of ND in external genitalia was reported as the cause of a paraffinoma and an above skin ulceration by Balighia and colleagues, in a 56-year-old man 83. They also cause biochemical modifications of prostatic secretion and seminal liquid. Most of these degenerative changes are partially reversible after treatment suspension 33,55,56. But studies show that overuse or misuse of nandrolone or any other anabolic steroid could be bad or dangerous for your health.
Misuse usually starts with a purpose — most often to help athletes build muscle or improve performance. Because of the serious health risks, most sports organizations have banned anabolic steroids like nandrolone. The vocal tissue, consisting of the vocal cords and the larynx, are part muscle, and 5α-reductase is expressed minimally or not at all in this tissue (Bhagavan, 2002; Kicman, 2008).
Nandrolone aromatizes at a rate of 20% that of testosterone, but when it comes to aromatization, we’re talking about the conversion of testosterone into estrogen. This will only happen when testosterone interacts with the enzyme known as a aromatase. When these conversions tend to happen, estrogen levels occasionally get elevated, which will result in unfavourable effects like gyncomastia and the retention of liquid in the body. With greater levels of liquid in the body, this means that your blood pressure can really go up to a high level. When you’re also dealing with lower levels of aromatase activity, you also have to realize that Nandrolone can serve as a progestin, which means that it will strongly bind to the progresterone receptor (PgR).
Similar findings have been made for derivatives of nandrolone like normethandrone and norethandrolone (Feldman et al., 1960; Roche, Towns, & Wettenhall, 1963; Kirschvink et al., 1963; Prunty et al., 1958). A little-known fact about testosterone is that it has weak affinity for the progesterone receptor (PR) and is a weak progestogen (Wiki; Bardin & Janne, 1986). The primary cardiovascular side effects of Nandrolone surround cholesterol, especially the reduction of HDL cholesterol (good cholesterol). Data has shown that the negative impact on HDL can be greater with Nandrolone than Testosterone. This is not the unfriendliest steroid to cardiovascular health, most oral steroids will have a much stronger negative impact, but we can’t call it the friendliest either.A cardiovascular friendly lifestyle is very important if supplementing with Nandrolone. The individual’s diet should be rich in omega fatty acids and low in simple sugars and saturated fats.
