Nandrolone Esters - Dragon Pharma

Buy Deca-Durabolin (Nandrolone) by Dragon Pharma at XSteroids. Nandrolone is a 19-nor anabolic steroid, sold historically under the name Deca-Durabolin, and one of the most popular mass-building injectables in bodybuilding. Dragon Pharma combines the whole nandrolone line on one card: Deca 300, Deca 500, NPP 150 and the Deca 200 / NPP 150 blend, all in 10 ml vials. This guide covers how nandrolone works, doses, cycles, stacking and PCT.

Nandrolone is a synthetic version of testosterone with stronger anabolic and weaker androgenic activity. It is used medically to treat anemia and osteoporosis, and in bodybuilding for quality mass and joint-friendly cycles.

About Nandrolone (Deca-Durabolin) by Dragon Pharma

Nandrolone, also known as 19-nortestosterone, differs from testosterone at a single carbon position, which changes how the body uses it: more tissue-building power and fewer androgenic effects. Medical use includes anemia, where it stimulates red blood cell production, and osteoporosis. It is a controlled substance and is no longer marketed in the United States.

This card offers both nandrolone esters: Decanoate, the long-acting classic available as Deca 300 and Deca 500, and Phenylpropionate (NPP 150), the shorter-acting ester. The Deca 200 / NPP 150 blend combines both esters in one vial.

How Nandrolone Works

Mechanism of Action

Nandrolone binds to the androgen receptor and increases protein synthesis and nitrogen retention, which drives gradual, quality muscle gains that are easier to keep after the cycle than fast water-based gains. It also stimulates red blood cell production, which improves recovery, and supports collagen synthesis, which many users report as joint comfort during heavy training.

Why Bodybuilders Use It

Nandrolone is a staple of bulking cycles for solid, long-lasting mass, and it is often preferred over harsher compounds for its relatively mild side effect profile. Because the decanoate ester is long-acting, Deca is injected once or twice a week, while the shorter NPP ester needs more frequent injections.

Nandrolone Doses and Cycles

Dosage

Beginner protocols commonly run 200 to 300 mg of nandrolone per week, and intermediate or advanced users 400 to 600 mg per week. Weekly doses are usually split into two injections to keep blood levels stable. The Deca 200 / NPP 150 blend delivers 350 mg per ml of combined esters.

Cycle Length

Nandrolone cycles typically last 8 to 12 weeks. Because the decanoate ester stays in the body for weeks, recovery planning matters: natural testosterone is strongly suppressed, and post-cycle therapy is required.

How to Stack Nandrolone

A classic bulking stack combines nandrolone with a Testosterone base, often with an oral kickstart such as Dianabol in the first weeks. Equipoise is another popular mass-building partner for longer cycles.

Nandrolone aromatizes more weakly than testosterone, but estrogenic effects are still possible, so an aromatase inhibitor such as Arimidex should be kept on hand and dosed by blood work. Proviron is a common addition for libido support on 19-nor stacks.

PCT and Recovery After Nandrolone

Nandrolone strongly suppresses natural testosterone, and because the decanoate ester clears slowly, PCT starts later than with short esters. A typical protocol uses HCG where needed and then a SERM such as Nolvadex or Clomid for several weeks. Blood work is the only reliable way to confirm recovery.

Nandrolone Side Effects and Precautions

Nandrolone suppresses natural testosterone production, which can cause low libido if no base is used. It aromatizes less than testosterone, so water retention is usually milder, but estrogenic effects are still possible. As a 19-nor compound it can raise prolactin in some users, especially at high doses or in combination with other 19-nor steroids. HDL cholesterol can drop, and blood pressure should be monitored. Nandrolone is intended for adult men and is not for use by women or minors.

Storage Instructions

Store the vials at room temperature in a cool, dry place, away from direct sunlight and temperature extremes. Do not freeze the oil-based esters. Keep the vials sealed until use and out of the reach of children.
