Deca Durabolin (Nandrolone Decanoate) 300mg/ml – NovoPharm



What is it: Novo-Pharm Deca Durabolin, aka Nandrolone, is an anabolic steroid used for off-season bulking. It’s one of the most potent options on the market, though it has several notable side effects.

Used for: Significant muscle growth, strengthening of the bones and ligaments, alleviating joint pain, endurance improvement. It’s a classic bulker in an injectable form.

How to use: The Deca Durabolin cycle usually lasts 8-10 weeks, with doses of 200 to 600 mg or more per week. It is recommended to stack Deca with injectable testosterone to avoid testosterone suppression.


Novo-Pharm’s Deca Durabolin is an anabolic steroid commonly used for off-season bulking. Compared to Testosterone, it is less androgenic and more anabolic, despite being a Nandrolone-based compound.

Nandrolone, also known as 19-nortestosterone, is an anabolic steroid that can be produced in the human body after intense physical exertion or during pregnancy, although the concentration is generally very low, usually only a few nanograms per milliliter.

Since its introduction in 1962, Deca Durabolin has been widely regarded as one of the most effective and popular steroids in the community. It has become a Golden classic, alongside other popular steroids like Dianabol, Anavar and Testosterone.

The popularity of Novo-Pharm's Deca Durabolin can be attributed to its ability to deliver significant muscle growth, up to 8 kg of muscle mass in one cycle with minimal rebound.

Additionally, it can strengthen bones and ligaments by stimulating collagen synthesis, and alleviate joint pain through increased production of synovial fluid.

Moreover, Deca Durabolin enhances the production of red blood cells, which leads to improved oxygen transportation and greater endurance.

One of the main advantages of Novo-Pharm's Deca Durabolin is its low probability of side effects, as its low androgenic activity makes side effects such as acne, baldness, and body hair growth rare.

However, it is important to note that these side effects are still possible with any steroid, especially if doses exceed the recommended ones.

The Deca Durabolin cycle usually lasts 8-10 weeks, but some athletes on an endless blast and cruise cycle may use it for up to six months by gradually increasing doses, although this is not recommended. To avoid progestin effects and testosterone suppression, it is recommended to stack Deca with injectable testosterone.

To minimize the risk of side effects, it is advised to take Nandrolone in doses of 200 mg or more per week, starting with lower doses. 

The healthy limit is around 600 mg per week. Taking higher doses increases the risk of side effects, making it more beneficial to complete two cycles with breaks at reasonable doses, rather than one in high doses.

Structurally, Nandrolone differs from testosterone by the absence of just one carbon atom at position 19, which makes it more similar to progestins. Another difference is that testosterone in the body gradually converts to a powerful androgen - dihydrotestosterone, responsible for most side effects, through the enzyme 5-alpha reductase.

Deca, on the other hand, is converted by 5-alpha reductase into an extremely weak androgen called dihydronandrolone, which has almost no effect on the body and does not cause side effects. This bonus effect adds to Novo-Pharm's Deca Durabolin's legendary image.
