In the two decades or so that we’ve utilized AAS, Deca Durabolin has almost been a staple in our bulking cycles.

When we changed from the 3 cycles annually regular to B & C for some time, we chose to use it as a part of their blasts.

In fact, we might be one of the few who have utilized it in reduced doses even during our cuts.

So it seems surprising to us that such a valuable (and gentle ) anabolic steroid is sparingly used nowadays.

For the uninitiated, Deca is one of the oldest Anabolic steroids in the world.

For many years, it was a ‘Russian Dope Machine’ favored and even back home, a great deal of the legends of the 70s and 80s have been believed to be using Deca.

If you end up getting swayed by newer and faster-acting steroids such as Trenbolone, then here’s the low down on one of the finest anabolic steroids which you may ever use.

Chemical Structure

Deca Durabolin is derived from Testosterone by building a simple modification to the carbon atom at the 19th place.

The outcome is Nandrolone, a very versatile hormone using an anabolic rating marginally above testosterone. But having an abysmal rating of just 37.

Nandrolone has been attached to a variety of esters over the years. Some of that was used quite broadly, like Nandrolone Phenylpropionate.

But it’s the slow-acting Decanoate ester, that has remained the most popular of them all.

Frequent Names

Nandrolone Decanoate premiered under the name’Deca Durabolin’ by Organon, way back in 1962.

A whole lot of spin-offs bombarded the market soon after. But surprisingly, it’s the Deca Durabolin brand name that has stuck.

Main Uses

Deca Durabolin gained a reputation among the trios of the ‘golden age’ bulking stacks. Both of the other steroids at the pile have been Dianabol and Testosterone Enanthate.

Dianabol would kick in a week or so. The evaluation would kick in around week 4-5, whereas Deca Durabolin, the slowest of them all would kick by week 10 approximately. In time, when the consumer has dropped most of the glycogen and water obtained on Dianabol.

But calling it a pure bulking steroid is a misconception. It’s a very versatile steroid that can be used in multiple ways.

Below are some of the chief applications of Deca.

Collagen Synthesis

Not quite what you would expect from an anabolic steroid. However, Deca Durabolin has attained legendary status in athletic circles because of its efficacy in improving bone mineral density and fostering collagen synthesis. Any athlete or athlete with joint pains or ligament tears will experience great relief with even low doses of Deca. It’s like being on a mixture of painkillers. Only, it’s not half as toxic as painkillers are. This is only one of the reasons why professional bodybuilders add Deca to each stack, despite it being a ‘wet benefits’ steroid. It eliminates muscle cramps and joint niggles caused by competition prep orals.

Lean Majority

Deca Durabolin is a really powerful anabolic compound. A lot of professionals use it like an off-season bulking compound due to its slow-acting character and because the mass obtained Deca seems to be of better quality than what you’d gain with Dianabol or Anadrol. There’ll be some quantity of water retention. But it is one of the simplest steroids to control. Also, the’rollback’ or loss of muscle following the cycle is minimum provided you continue to eat and lift directly.


Among the therapeutic uses of Deca is improving the quality of life in geriatric care. It reduces fatigue and prevents muscle loss. So, strength advantage is just one of the underrated advantages of Deca Durabolin. What’s noteworthy, is that unlike oral steroids, the strength profits created on Deca are much less dramatic. It will be slow but sustainable.

Nitrogen Retention

Deca is one of the most effective steroids for boosting nitrogen retention. Much more effective than Trenbolone even. We all know the advantages of a positive nitrogen balance, do not we? It’s among the building blocks of Anabolism.

Side Effects

Deca Durabolin is one of the mildest anabolic steroids if you compare the side effects together with the outcome that you can achieve with it.

Having said that, it still is a very powerful steroid and some sides will probably be unavoidable.

  • Estrogenic Side Effects: Deca Durabolin aromatizes very weakly, at only 20% of that of Testosterone. However, it has a strong progestin character which makes side effects such as bloating and gynecomastia, a slender but definite possibility. You must use a SERM, like Nolvadex in place of an AI (Aromatase Inhibitor) whenever possible. AIs can wreck your cholesterol levels, something that might be of concern when you are using Deca.
  • Androgenic: once more, the chance of this happening is slim unless you are exceedingly sensitive to androgenic sides. But if you do experience rapid or acne hair loss or competitive body hair growth, then it is a little difficult to control as 5-alpha reductase inhibitors are ineffective against Deca Durabolin. Women must adhere to low doses to prevent virilization symptoms.
  • Cardiovascular: Deca Durabolin has a negative impact on HDL and in Addition, It increases the level of LDL. On the other hand, the cardiovascular side effects should be familiar using a cholesterol-friendly lifestyle and diet plan. This should be a matter of concern though for bodybuilders that are stacking Deca with a 17C-AA oral steroid.

Dosage And Stacks

Beginners should begin with 250-500mg/week for a 12-16-week cycle.

More sophisticated users can this up to 600mg/week. But that’s the upper limit that we would stick to, even when you’re using Deca as the foundation with a TRT dose of test.

On the flip side, if you are only seeking to use Deca for your curative benefits, then proceed for 100-150mg/week for 12-weeks.

We spoke in brief about the very popular bulking stack of all times, Dianabol, Deca and Test-E.

Other than this, Deca can also be stacked with orals like Masteron and Winstrol to reduce the painful cramps that they cause.

A Tren and Deca cycle is rare. However, we’ve seen an increasing number of athletes experimentation with it lately, with decent results to show for this.
