Nandrolone cypionate originates from the well-known steroid, Nandrolone. The key difference is that it is an injectable form of the mentioned steroid. The pattern of the hormone’s release is identical to that of testosterone. The climax or the highest levels were noted 24-48 hours after administration. However, a significant portion of the hormone is still released for another week. The active substance is obviously Nandrolone. The latter has some androgenic and oestrogenic properties.
What should be specifically underscored is the fact that Nandrolone Cypionate is actually a modified version of its precursor. The difference is that, unlike Nandrolone, the injectable version has a carboxylic acid ester attached to the 17-beta hydroxyl group. This reduces the steroid’s polarity which results in the slower absorption by the body.
Having recalled all that above, we now move on to discussing the side effects. Firstly, it is oestrogenic which implies that Dynabol contributes to the conversion of testosterone to oestrogen. This can be simply explained by the fact that the liver cannot convert Nandrolone to estradiol.
Secondly, the anabolic steroid can also prove to be androgenic. The main cause of this effect is related to overdosing. These androgenic properties include acne and facial hair growth.
Besides, these can result in aggravated hair loss in men and virilization in women.
Finally, Nandrolone may lead to cardiovascular problems due to the increase in bad cholesterol levels.
