Deca Durabolin (Nandrolone Decanoate) Steroid Profile                                               

Brand Name: Deca Durabolin

Active Ingredient: Nandrolone Decanoate

Drug Class: Anabolic/Androgenic steroid

Half-Life: 14-16 days

Legal Category: Prescription only medicine (POM)

Deca Durabolin is the second-best known anabolic androgenic steroid UK after testosterone because of its best results. It is popular as “Deca” among athletes and bodybuilders who use it for mass building in the off-season. The Organon Company first manufactured Deca Durabolin in 1962 to treat patients suffering from “muscle wasting” (cachexia).

Deca Durabolin is also known as 19-nortestosterone because, unlike testosterone, it lacks the 19th carbon atom in its structure. It is the only prescribed and FDA-approved anabolic steroid used to effectively treat patients with anaemia and AIDS because of its erythrocytosis and anabolic properties.

Why Is It So Popular Among Bodybuilders?

Many bodybuilders and athletes have been using Deca Durabolin to be in shape for any competitive event and improve their overall performance. Deca Durabolin helps build stamina (to keep training sessions going longer) and muscle recovery. Simply put, Deca Durabolin, when combined with a healthy diet and regular exercise, adds stamina, improvements, and strength to the overall physique [1].

Benefits Of Deca Durabolin:

The following are some known benefits of Deca Durabolin:

1. Faster Muscle Recovery Rates:

Deca Durabolin helps people gain more strength and energy because it regulates cortisol in the body produced due to the stress of weight lifting.

2. Increased Testosterone Levels:

Deca Durabolin boosts your testosterone levels, which in turn increase your stamina and strength. Increased stamina helps bodybuilders train for more extended periods. Deca Durabolin does not cause a sudden increase in testosterone levels. Instead, it results in a steady increase in strength that is more advantageous and sustainable.

3. A Gain in Overall Mass:

Deca Durabolin contains an effective bulking component called nandrolone. It results in an overall increase in mass when used in the right way. For example, many bodybuilders use it during their off-season so that they’re bigger and better during competition [2].

4. Increased Red Blood Cell Production:

When used frequently between workout sessions, Deca Durabolin increases the production of red blood cells and oxygen supply to your muscles and tissues. Increased RBC production helps people work for longer without getting fatigued.

Dosage and Administration:

Deca Durabolin comes in a 200 mg/ml injectable solution. To develop muscle mass, the optimal dose of Deca Durabolin is 200-600 mg per week. Mostly, athletes take 200-400 mg of Deca Durabolin per week .

Side Effects of Deca Durabolin:

When used in excessive amounts, Deca Durabolin has the following side effects:

1. Low Testosterone:

Deca Durabolin is a highly suppressive anabolic steroid that causes low testosterone levels. Many bodybuilders thus have to discontinue the drug and take a PCT involving clomiphene or tamoxifen to increase the production of endogenous testosterone.

2. Estrogen and Progesterone:

Deca Durabolin exhibits only a 20% aromatization rate, meaning that it has low estrogenic properties. However, due to increased progesterone, many people experience estrogen-like side effects like gynecomastia.

3. Deca Dick:

One of the sexual side effects of Deca Durabolin is a decrease in sexual desire and performance that may lead to erectile dysfunction (Deca Dick).

The reason why many men experience Deca Dick is due to its decreased androgenicity. Androgenic steroids are responsible for the production of nitric oxide, which supplies blood flow to the penis. Deca Durabolin interferes with circulation in this regard [3].

4. Cholesterol:

Excessive doses of Deca Durabolin provoke high blood pressure by increasing LDL cholesterol and decreasing HDL cholesterol [4].

    Bought Deca and Tesat E from them 6 weeks ago and they are fantastic-for product quality and communication you have five stars. Only reason for four stars in final rating that there is still no photos on the web. C’mon guys-products are beautiful :)!

    • Peter

      Hi Chris
      Thank you for the feedback. We should be having photos shortly so hopefully, this will give us 5 stars with your next purchase. Please drop us a line how the cycle is going further down the road and what you achieved.
      All the best

    Good legit oils with great service-recommended!

    • Peter

      Hey Mike
      Thank you for your trust. Our aim is quality so you can get the most from the workouts. Lets us know-hows Deca.

  3. Michael

    Was looking for slightly longer cycle-12 weeks one, to gain size. Finished last week with the suggested combo with Prop. Dosing recommended by guys from SPH was really on the spot. Couldn’t believe that if I go with lower doses of Deca the gains can be so good-trust me guys, wanted to go with 600mg/deca as guys on the gym were saying but end up with the recommendation of SPH, simply outstanding lab/guys!

    • Peter

      Hi Michael
      We always say that quality will beat the quantity. If you have good gear that is not being under-dosed you don’t have to go ridiculous high with the amount of the oils. We always try to help our clients the best what we can but the decision is always in their hands. W are grateful for your trust and believe that you will return to us next time. Wish the best results.

    Sceptical about new player in the market. Ordered Dbol, Deca and Test E as a cycle. Dbol kicked in like hell, waiting for Test and Deca to take full swing and most probably will change all my wardrobe

    • Peter

      Hi Jason,
      This is beautiful cycle-Orals generally kick very quickly deca and Test E will spin their wheels soon so be ready for the ride:)
      Hope that cycle will go well
      Thanks a lot for the trust in the brand
