nandrolone phen


Nandrolone Phenylpropionate (NPP) CAS:62-90-8 is an anabolic steroid in the form of an injection. The properties of this drug are very similar to those of DECA nandrolone decanoate which releases more slowly. The main difference between these two formulations is the rate at which Nandrolone is released into the blood. The release time of DECA nandrolone decanoate will last about 3 weeks from the day of injection, while the release time of NPP nandrolone phenylpropionate will be about one week. In clinical use, DECA nandrolone decanoate can be injected once every 2-3 weeks, while NPP nandrolone phenylpropionate is usually administered every few days to once a week. In addition, the difference between the two drugs is not much. Like DECA nandrolone decanoate steroids, NPP nandrolone phenylpropionate is favored by athletes and bodybuilders because of its ability to increase strength and lean muscle without obvious estrogen or androgenic side effects.

The Nandrolone Phenylpropionate (NPP) CAS:62-90-8 first appeared in 1957. It was soon listed as a prescription drug, and the international pharmaceutical giant Organon (now Merck/MSD) entered the market under the trade name Durabolin. NPP nandrolone phenylpropionate was used for lean muscle preservation before and after various operations, osteoporosis, weight loss due to rehabilitation or disease and general weakness. , Burns, severe trauma, ulcers, adjuvant treatment of specific forms of anemia, and cases of growth retardation in children.

Structural characteristics of NPP nandrolone phenylpropionate:

NPP Nandrolone Phenylpropionate is a modified form of the original Nandrolone, in which the carboxylate (phenylpropionate) is attached to the 17-β hydroxyl group. Esterified steroids are less polar than free steroids and will be absorbed more slowly from the injection area, the lipid chain is removed and free (active) Nandrolone is obtained. Esterified steroids are designed to extend the therapeutic window after administration, and the injection frequency is lower compared to free (unesterified) steroids. 24-48 hours after deep intramuscular injection, the release of NPP nandrolone phenylpropionate increased sharply and dropped to close to the baseline level within a week.

Nandrolone Phenylpropionate (NPP) CAS:62-90-8 is a modified form of nandrolone in which the phenylpropionate is linked to the 17-β hydroxyl group. Esterified steroids are less polar than free steroids and are absorbed more slowly from the injection area. the ester is removed and free (active) Nandrolone is obtained. Esterified steroids are designed to extend the window of therapeutic effect after administration. Compared with the injection of free (unesterified) steroids, the frequency of injection of esterified steroids can be less close. Nandrolone phenylpropionate is released within 24-48 hours after deep intramuscular injection and reaches a peak serum level, and drops to near baseline levels within a week.
