Nandrolone Decanoate 300

This is nandrolone decanoate, commonly called Deca, a long-acting injectable steroid dosed at 300mg per ml. It is known for steady, quality muscle gain, joint comfort and a mild oestrogen conversion, and is almost always run with testosterone.

As a general guide and not medical advice, users commonly inject 300 to 600mg per week for 12 to 16 weeks, alongside a testosterone base. Because the ester is very long, it takes time to build up and clear. Always confirm dosing with a healthcare professional.

The most commonly reported effects are water retention, a rise in prolactin, and suppression of natural testosterone. Deca is slow to recover from, and libido issues can appear if a testosterone base is not used. Regular bloodwork and a testosterone base are sensible precautions.

Yes. Nandrolone suppresses natural testosterone production, and its long ester means recovery takes longer than with most other compounds. A full PCT is required, usually starting around three weeks after the last injection. This is general information, not a prescription.
