Substance: Nandrolone Phenylpropionate
Durabol is a fast-acting form of nandrolone. Nandrolone is chemically related to the male hormone testosterone. Compared to testosterone, it has an enhanced anabolic and a reduced androgenic activity. This has been demonstrated in animal bioassays and explained by receptor binding studies. The low androgenicity of nandrolone is confirmed in clinical use. In the human, nandrolone has been shown to positively influence calcium metabolism and to increase bone mass in osteoporosis. In women with disseminated mammary carcinoma, nandrolone has been reported to produce objective regressions for many months. Furthermore, nandrolone has a nitrogen-saving action. This effect on protein metabolism has been established by metabolic studies and is utilised therapeutically in conditions where a protein deficiency exists such as during chronic debilitating diseases and after major surgery and severe trauma. In these conditions, nandrolone phenylpropionate serves as a supportive adjunct to specific therapies and dietary measures as well as parenteral nutrition, due to it's faster acting nature nandrolone phenylpropionate is preffered in situations where a faster clinical response is required over it's chemical variant nandrolone decaonate.
Nandrolone is one of the few steroids which has been used successfully in AIDS patients to stimulate weight gain (3), and although athletes using NPP in lieu of Deca find it to produce slightly less weight gain, this is probably a result of gaining less water weight. Nandrolone Phenylpropionate, is a more popular drug than Deca for use in cutting cycles recently, due to this fact.
This brings up the fact that although Deca has a very long active life, NPP has a much shorter one, and this means that people are forced to inject at least two times per week, with the more common protocol being every third day. Results are seen much more quickly with NPP as compared with Deca, and it??s quickly becoming a much more popular alternative.
Usual dosage for Nandrolone Phenylpropionate is around 50-100 mg per injection, or a total of 150-300 mg/week with the 1-2 ml injections, which are more pleasant than 2-4 ml injections. Because Durabolin is of higher concentration a smaller injection is used meaning there is less risk of infection and the experience is generally more comfortable.
Due to its highly anabolic nature coupled with low androgenic properties it can be incorporated into a mass cycle, usually stacked with testosterone and a powerful oral like possibly oxymetholone (Anadrol) or methandrostenolone (Dianabol). Durabol can thus be part of a classic bulking cycle.
For a cutting cycle NPP is usually be combined with other short-estered injectable anabolic steroids (testosterone propionate and boldenone acetate come to mind as likely choices) and one of the DHT derived orals such as stanozolol (winstrol) or oxandrolone (Anavar). Durabol is said to produce good mass and strength gains in both cutting and bulking cycle phases. When one is planning a cutting cycle one must take caution if combining the 19-nor-testosterone derivative trenbolone with nandrolone. Trenbolone Acetate, although a powerful drug for lean muscle gains, strength, and fat loss is also a strong progestin with a binding affinity 3x that of nandrolone).
Gains from Durabol are reported to be “clean” with minimal water retention and fat gain. While Deca-durabolin is usually used in “bulking” cycles, Durabol is used in “cutting” cycles although either drug can be used in either regard.
One of the most popular anabolic steroid used in bodybuilding cycles, nandrolone is also (medically) used to treat severe debility or disease states and refractory anemias.
Although many nandrolone lovers claim that it is one of the safest anabolic steroids, if not the safest. It does have side effects that can be bothersome in hypersensitive individuals, such as acne, excitation, insomnia, nausea, diarrhea and bladder irritability.
