Deca 200 / Npp 150 contains:

Nandrolone Decanoate - 200 mg/ml
Nandrolone Phenylpropionate -150 mg/ml

Deca is a low androgenic steroid with high anabolic effect. It will aromatize in high dosages, but not at the rate of testosterone. Progesterone buildup is one side effect that some have trouble with. Users sensitive to these issues might choose to add Cabaser or Dostinex to their cycle.

Deca can be used for cutting or for bulking. Bodybuilders often stack it with Testosterone for one of the most common and effective bulking cycles. The Deca /Winstrol stack is also very popular. It is believed that Winstrol helps block the progesterone buildup while the Deca heIps with the joint issues that some suffer while on Winstrol. The joint relief and healing that Deca provides is one of the main reasons it has become a very popular steroid with bodybuilders.

Npp is an injectable form of the anabolic steroid Nandrolone. The properties of Npp are strikingly similar to those of Deca Durabolin, which uses the slower acting drug Nandrolone Decanoate. The primary difference between these two preparations is the speed in which Npp is released into the blood. While Nandrolone Decanoate provides a release of nandrolone from the area of injection lasting approximately 3 weeks, Npp is active for only about a week.

Npp is fast acting steroid and therefore makes it possible for the compound to be out of the body much more quickly. This makes Npp a better choice than Deca for tested bodybuilders and athletes. Users typically follow a dosage schedule of every other day when using Npp to keep blood levels elevated and stable.

Npp seems to produce less water retention than its longer acting counterparts, and this would be very consistent with injectable testosterones, where shorter esters provide much less water retention.

Npp is a progestin, like any Nandrolone derivative. However, although it’s a progestin, Npp (regardless of ester) doesn’t produce much of estrogenic side effects. Any side effects from Nandrolone Phenylpropionate would therefore more properly be termed progestenic in nature- as it only converts to estrogen at roughly 20% the rate of testosterone.
