Nandrolone is one of the best known steroids in the history of bodybuilding. Originally synthesized in 1950s, athletes quickly found there was a good use for this powerful steroid. As far back as the mid 1960’s nandrolone has been used as a great addition to a dianabol and/or testosterone cycle. Since nandrolone works for any athlete looking to increase the amount of steroids he is using, without increasing the side effects, it has been a favorite of many old school bodybuilders. In simple terms, deca allows you to use more steroids, without having more side effects.

Interestingly, trace amounts of nandrolone have been found in the urine of pregnant women after the 6th week; as a result, we know that it is possible for a human body to make base nandrolone.

Chemical Structure

Nandrolone is the base hormone, but it is better known under the trade name Deca Durabolin, which contains Nandrolone Decanoate. This popular preparation takes the nandrolone hormone and adds a decanoate ester chain. This ester chain is attached during the manufacturing process and it serves dual purposes. The main purpose is to make the hormone oil soluble, so it can be put in an amp or multi-dose vial. The second purpose of this ester chain is to slow-release the steroid by keeping deca from interacting with androgen receptors until the ester chain is cleaved off by enzymes in your body. Since nandrolone decanoate cannot attach to an androgen receptor until enzymes in your body have cleaved off the decanoate ester, it causes the steroid to slow-release into your system over many days. For medical use, the ester’s main function is to allow the hormone to be injected only once every 3 weeks. However, bodybuilders may inject deca durabolin weekly or as often as every three days.

What is Deca Durabolion (Nandrolone Decanoate)?

Since the mid 1960’s, Deca Durabolion has become a staple in most testosterone and/or dianabol cycles, the main reason is that Deca adds a lot of strength to a cycle without increasing side effects.

When used in a testosterone and/or dianabol cycle, deca really adds weight to the cycle without much more stress on the system. Deca does not add additional side-effects when used with other steroids, but it should never be used alone. Standalone use of nandrolone comes with its very own set of nasty side-effects, the most infamous of them all is the dreaded “Deca Dick”, where the affected user is unable to get or sustain an erection. This is due to the fact that without the stronger testosterone metabolites like dihydrotestosterone (DHT), the softer and much weaker metabolites from deca will flood your receptors, not leaving room for stronger androgens. Not only are deca’s weaker metabolites an issue when there is an absence of stronger androngens, but nandrolone itself can, and will, attach to progesterone receptors. This causes side effects that only affect the user in the absence of supraphysiological amounts of stronger androgens.

The best way to explain deca durabolin is that it’s basically a progesterone-like hormone that builds muscle mass, strength and, to a lesser degree, helps repair joints. It should not give you any bad side effects when used with stronger androgens that will mask and counteract possible problems from nandrolone. If ever used by itself, the bad side-effects from nandrolone will crush your libido, sexual desire, cause bloating and gynecomastia (bitch tits).

How to inject Deca Durabolin?

Since deca durabolin is formulated using nandrolone decanoate, one of the longest esters in existence, it is very oil soluble, the way all steroids with long esters are. This easy solubility in oils means that manufacturers have to use a lower percentage of solvents to manufacture the products; thus, making for a less irritating shot. Generally, deca injections are done weekly by most bodybuilders.

What are the dosages Dosages? and how to use deca?

By adding 400mg per week of nandrolone to a testosterone cycle or a dianabol cycle, you’ll be able to increase your overall steroid dosage, without increasing the side effects. For example, a bodybuilder taking 500mg Sustanon 250 per week, who felt he needed more power in his cycle, would find himself with more side-effects if he were to just take more of the same testosterone. Since testosterone aromatizes at an increasing rate at higher doses, there would be an exponential increase in the likeliness of gynecomastia and water retention if more testosterone was added weekly. When adding nandrolone decanoate to the same testosterone cycle, you are increasing the total amounts of steroids your body is receiving every week. However, you are not adding anymore viable substrate for undesired enzymatic reactions from aromatase and 5-reductase. In simple terms, you use more steroids without more side effects.

The dosage for men is around 400-600mgs per week but that varies depending on goals. I’ve seen guys use as little as 200mgs per week as a booster, and up to 1500mgs per week as a heavy bulker.

For women, I wouldn’t suggest using deca durabolin because of the side effects that are too variable from female to female.

Can you give me some deca cycles?

Sure, I’ll give you the testosterone, deca durabolin and dbol cycle, but this same cycle can be used without test – assuming you replace with sustanon.

What is the half-life of deca durabolin?

The half-life of deca durabolin is about 6 days, but it takes around 21 days to be excreted from your system. In fact, some athletes have tested positive for the metabolite months after their last injection, so be careful with deca.

Does deca durabolin have side effects?

Nandrolone should only cause adverse side effects when used by itself, or when the amount is too high for the amount of testosterone being used. A good rule of thumb is to use a ratio of 3:2 – testosterone to nandrolone. Therefore, if you were doing 600mg of testosterone per week, your deca durabolin dosage should not exceed 400mg. Again, the main problem with deca is that in the absence of enough testosterone to act as the substrate for dihydrotestosterone (DHT), a vital part of your erection, the body will get flooded with much weaker nandrolone metabolites that will out-compete your body’s own production of DHT. Injecting deca by itself will cause a flooding of receptors meant for DHT, with weaker hormone that will not impart the proper signal to allow for a proper erection. This is called “Deca Dick.”

Side effects when stacking deca durabolin are a little different. As we all know, deca is usually stacked with test and dbol. The problem is that testosterone and dianabol are known to cause major side effects like water retention and the growth of breasts in men (gyno). These effects stem from these steroids being converted to estrogen (from testosterone) and 17á-methylestradiol (from dianabol) by the aromatase enzyme. Other side effects these two steroids display are major hair loss and enlarging of the prostate, mainly due to testosterone’s conversion to dihydrotestosterone via its inevitable interaction with the 5-reductase enzyme. Although nandrolone has some limited interaction width both the aromatase and 5-reductase enzymes, the metabolites resulting from these interactions do not cause the same extreme side effects as test and dbol. Therefore, deca durabolin is basically a synergetic steroid that work well with all other bulking steroids. Allowing you to bulk more without more side-effects.
