Product overview
Nandroxyl - Nandrolone Decanoate and Phenylpropionate Injection
Nandroxyl delivers nandrolone in two injectable forms in 10 ml multi-dose vials: Decanoate 250 for a slow, long interval and Phenylpropionate 100 for a faster release. Nandrolone is a 19-nor anabolic steroid used for quality mass, strength and joint comfort, and it is usually added to a testosterone base rather than run alone. Buy nandrolone as a long ester, Decanoate 250, or a short one, Phenylpropionate 100, depending on how often an injection fits the schedule.

Variant Comparison
Both vials hold the same hormone; the ester sets the release speed and the injection interval. The table compares concentration, half-life and a typical schedule.
| Formulation | Concentration | Half-Life | Inj. Frequency | Typical Use |
|---|---|---|---|---|
| Nandrolone Decanoate | 250 mg/mL | ~6-12 days | Once weekly | Long cycle |
| Nandrolone Phenylpropionate | 100 mg/mL | ~4.5 days | Every other day | Short block |
The difference is how quickly each ester is absorbed and how often the vial is opened. Decanoate 250 is the slower ester, so one weekly shot holds a steady level through a long block, while Phenylpropionate 100 clears faster and is injected every other day, which suits a shorter phase or a cycle that is tapered near the end. A testosterone base such as Testoxyl is normally added, since nandrolone shuts down natural production on its own, and a non-aromatising injectable such as Boldaxyl 300 keeps a stack lean.
How Nandrolone Works
Nandrolone is a 19-nor anabolic steroid. It binds androgen receptors and supports protein synthesis and nitrogen retention, the mechanism behind gains in lean mass and strength, with a lower androgenic profile than testosterone and a slower conversion to estradiol. It also supports red blood cell production, and the medical form is indicated for the anemia of renal insufficiency. Because it carries progestogenic activity, estrogen and prolactin side effects are watched, and the injections suppress natural testosterone, so a base and a recovery plan belong in the cycle.
Dosage & Administration
Nandrolone is injected into the muscle. Decanoate 250 is commonly run at 250-400 mg once a week and Phenylpropionate 100 at 100-150 mg every other day, for eight to twelve weeks alongside a testosterone base. Rotate sites and use a clean technique. An aromatase inhibitor such as Arimixyl is used if estrogen side effects appear, and because the injections suppress natural production, recovery starts after the last shot with Nolvadex 20 mg daily for four weeks, or Clomid as the alternative. Follow your prescribing physician's instructions.

FAQ
Nandroxyl is an injectable nandrolone line used for quality mass, strength and joint comfort. Medically, nandrolone decanoate is indicated for the anemia of renal insufficiency, where it raises haemoglobin and red cell mass. In training it is added to a testosterone base rather than run alone, because it suppresses natural production on its own.
The ester sets the schedule. Decanoate 250 is commonly run at 250-400 mg once a week, and Phenylpropionate 100 at 100-150 mg every other day, for eight to twelve weeks. Nandrolone is usually paired with a testosterone base, and a clinician sets the actual dose. Inject into the muscle, rotate sites and keep the technique clean.
Decanoate 250 is the slower ester, so one weekly injection keeps a steady level and suits a long block. Phenylpropionate 100 clears faster and is injected every other day, which fits a shorter phase and gives more control near the end of a cycle. Both carry the same hormone; the choice is about frequency and how quickly the level needs to drop.
Nandrolone can reduce testicular function, lower sperm count, cause erectile problems, acne, gynecomastia and fluid retention, and it changes blood lipids. Rarely it has been linked to liver cysts and liver tumours. Because it carries progestogenic activity, breast sensitivity is watched closely, and a testosterone base is used to offset libido and energy problems. Seek urgent care for chest pain or rapid swelling.
Yes. Nandrolone suppresses the body's own testosterone, and the longer Decanoate ester clears slowly, so recovery is started after the last shot. A common protocol is Nolvadex 20 mg daily for four weeks, with Clomid as the alternative, while a blood panel confirms that natural levels return. An aromatase inhibitor is used during the cycle only if estrogen side effects appear.
Alcohol is not a direct interaction for nandrolone itself, but it adds liver strain and raises blood pressure, both of which already concern this class of medicine, and it makes lipid and blood-pressure changes harder to read. Keep intake light while on a cycle and tell your prescriber about every medicine or supplement you take.
