19-Nor 250

"19-Nor 250 delivers up to 500% more active pro-hormone substrate for enhanced anabolic activity!"

Product Information
New 19-Nor 250 contains 250 milligrams of the pro-hormone 19-Norandrostenedione per capsule. 19-Norandrostenedione is a potent precursor substrate to the anabolic hormone nortestosterone. Through a natural enzymatic reaction, 19-Norandrostenedione is converted to nortestosterone. Nortestosterone is anabolic hormone that possesses a higher anabolic to androgenic ratio than testosterone - its anabolic properties are greater than its androgenic properties.

This is a very sought after quality for those who are sensitive to elevated androgens. With 19-Nor 250 you can take advantage of the anabolic (muscle building) properties that result from its natural conversion in the body to nortestosterone.

Though not as androgenic as testosterone, it adds a unique dimension to androgen onset muscle growth. You see, nortestosterone binds differently to the muscle cell's androgen receptor. The androgen receptor is a protein molecule on the surface of the muscle cell that allows the binding of an androgen molecule/hormone, sending the hormone's signal inside the muscle cell. It is theorized that the receptor affinity for nortestosterone is very high thus binding the molecule "tighter". This may make nortestosterone more efficient at delivering its "anabolic" signal for a longer period of time. This may equate to more sustained muscle growth.

19-Nor 250 contains 250 milligrams per capsule. Not the 50 or 100 milligrams found in other brands. Our research shows optimal nortestosterone elevation resulting in muscle growth and strength increases comes from 500 to 750 milligrams per day. Taking 50 or 100 milligrams twice daily may just have a minor impact on nortestosterone production and unless combined with other testosterone precursors will have little impact on muscle growth and strength. At 500 milligrams per day the effects are very noticeable.

19-Norandrostenedione is converted easily through an enzyme controlled reaction. Though it's been mistakenly reported that the conversion enzyme may be easily depleted with pro-hormone use, the enzyme used for 19-Norandrostenedione conversion, 17-BHD (17-beta hydroxysteroid dehydrogenase), is quickly replicated. This means 750 milligrams is well within the enzyme conversion threshold. You get full conversion and full anabolic (muscle-building) activity.
