Nandrolone Decanoate 300
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.
Nandrolone has become a name in sports and bodybuilding due to its ability to promote quantity and quality in bodybuilding. It promotes protein synthesis in the body, which is essential in building body mass and additional strength. As a relatively mild steroid (androgenic activity index: 37% as compared to testosterone), it can be used even by women and those concerned with hair loss because androgenic / virilization effects are less likely to develop.
Nandrolone is known to relieve muscle pain and speed up the regeneration process of the muscles. This drug is usually stacked with other anabolic steroids to achieve long-lasting and fast-acting effects. We highly recommend to always use nandrolone in stack with testosterone, because it instantaneously shutdowns your HPTA (hypothalamic-pituitary-testicular axis), which results in suppressing production of endogenous testosterone that being the primary man sexual hormone shall always present in a man body.
Another on feature of nandrolone is his ability to recover and strengthen bones and ligaments as well as to eliminate joint pain. Hence, if you have bad knees/joints, painful sensations in these areas nandrolone is the perfect compound for you to recover and strengthen them.
CAUTION: Tamoxifen on nandrolone cycles and on PCT (post cycle therapy) can strengthen progestogenic activity of nandrolone, so it should not be used. Clomid or toremifene are recommended for PCT after all 19-nor testosterone modifications.
