DECA-DURAOLIN (NANDROLONE DECANOATE 300MG/ML) – Steris Laboratories

Steris Laboratories Deca-Durabolin (Nandrolone Decanoate) is considered to be a classic drug for muscle bulk gain. Due to significant retention of water in muscles during the cycle, bulk growth occurs to be significantly faster. Combines well with long esters of testosterone.

With a half-life of around 6-7 days, it has slow release intended for long cycles.

Nandrolone (also noun as 19-nortestosterone or nandrolone deca) is an anabolic steroid, modification of testosterone, which may be produced in very small quantities in the human body after severe or prolonged physical activity.

Synthetic version of nandrolone was developed in 1950. But nandrolone for sale appeared later only in 1962 in the form of decanoate under the trade name Deca-Durabolin (Organon Company). It was prescribed for the treatment of postoperative loss of muscle mass, osteoporosis, breast cancer, malnutrition, burns and certain kinds of anemia.

Due to its chemical structure nandrolone is weakly exposed to aromatase (only 20% of the aromatizing activity of testosterone). However, not estrogenic effects are its main concern: nandrolone has a potent progestogenic activity (20% of progesterone). While binding to progestogenic pituitary receptors nandrolone causes increased production of prolactin, which in effect is very similar to estradiol. To prevent these side effects prolactin inhibitors (cabergoline) shall always be at hand when on nandrolone cycle.
