Deca 300 by Dragon Pharma
What Is Deca 300?
Deca 300 is Dragon Pharma nandrolone decanoate at 300 mg per mL - the classic Deca-Durabolin, one of the most proven mass-building injectables ever made. 3,000 mg per 10 mL vial.
Nandrolone is the steady, patient bulk compound: quality size, better appetite and recovery, and the joint relief that keeps older lifters loyal. The decanoate ester is slow, so levels build over weeks and the effect is long and even - not a compound for instant results, and not one to skip a test base on.
Deca 300 Dosage
Decanoate is a slow ester - two injections a week keep levels steady, and results build over weeks.
| Level | Weekly Dose | Per Injection (2x) |
|---|---|---|
| Moderate | 300 mg | 0.5 mL |
| Classic mass Common | 450-600 mg | 0.75-1.0 mL |
Cycle Length
One 10 mL vial at 450 mg weekly lasts about 6-7 weeks; a full cycle usually needs two vials. Always on a testosterone base.
Deca 300 Stacks
Nandrolone is always stacked on testosterone. Partners from the same Dragon Pharma line:

| Deca 300 + Enanthate 250 or Cypionat 250 | Testosterone base, equal or higher |
| Deca 300 + Dianabol 20 | Oral kickstart for the first 4 weeks |
| Deca 300 + Arimidex | Estrogen control |
Deca 300 Side Effects
Nandrolone sides are documented and manageable when the cycle is designed right.
- Estrogen - nandrolone aromatizes to a weaker estrogen, but water and gyno risk still exist.
- Prolactin - progestin activity at higher doses.
- Libido - deca dick is real; it comes from running deca without enough test or with crashed estrogen.
- Suppression - strong and slow to recover from; full PCT, started about 3 weeks after the last shot.
- Bloodwork - lipids and hematocrit mid-cycle.

What is Deca 300?
Deca 300 is Dragon Pharma nandrolone decanoate at 300 mg per mL - the classic Deca-Durabolin mass builder, 3,000 mg per 10 mL vial.
What does Deca-Durabolin do?
It builds steady, quality mass: better recovery, appetite and size over weeks, plus the joint relief that keeps users loyal. The decanoate ester makes it slow-acting and long-lasting.
Is Deca a testosterone?
No - nandrolone is a separate anabolic steroid. It is more anabolic per unit of androgen than testosterone and does not convert to DHT, but it still requires a testosterone base in the cycle.
How much Deca 300 should I take?
At 300 mg/mL, the classic mass dose is 300-600 mg per week - 0.5-1.0 mL twice a week. Nandrolone should stay equal to or below your testosterone dose.
Does Deca help joints?
Joint relief is the most commonly reported deca effect - collagen synthesis and water retention in connective tissue are the usual explanations. It is a major reason older lifters include it.
How do I avoid deca dick?
Keep testosterone equal to or higher than the deca dose, and do not crash estrogen with too much AI. Deca dick is a design problem - a proper test base prevents it.
When do I start PCT after Deca?
Decanoate clears slowly, so wait about 3 weeks after the last injection, then run SERMs such as clomiphene or tamoxifen until bloodwork shows natural testosterone recovering.
