Nandrolone Phenylpropionate – white or white with creamy tint crystalline powder with characteristic smell. Practically insoluble in water, difficult to dissolve in ethanol, easily soluble in chloroform and acetone. Nandrolone decanoate is a white to yellow crystal. Practically insoluble in water, freely soluble in ethanol, ether, acetone, chloroform, oils. Hypersensitivity, prostate cancer, breast cancer in men, breast carcinoma in women with hypercalcemia (capable of activating osteoclasts and causing bone resorption), pregnancy (having embryotoxicity, fetotoxicity, can cause female fetal musculinization); Acute and chronic liver diseases, including alcoholic lesions; Nephritis, nephrotic syndrome, breastfeeding.
It binds to specific receptor proteins on the surface of target organ cells, forms a receptor-nandrolone complex, providing transport of the latter through the cell shell to the hyaloplasm, from where it diffuses through the nuclear membrane into the cell nucleus and causes activation of regulatory genes. Androgenic properties include stimulation of nucleic acid (DNA, RNA) synthesis, structural proteins, enhancement of tissue respiration and oxidative phosphorylation in skeletal muscles with accumulation of macroergs (ATP, creatine phosphate); Increases muscle mass and reduces the amount of adipose tissue. It accelerates the growth of male genitals and the formation of secondary sexual signs by male type. It promotes calcification of growth zones in bones and cessation of skeleton growth.
