Duraxyl 100 by Kalpa Pharmaceuticals
Duraxyl 100 is an injectable steroid, this drug contains Nandrolone Phenylpropionate and is made by Kalpa Pharmaceuticals.
Duraxyl 100 is chemically related to the male hormone. 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, Duraxyl 100 has been shown to positively influence calcium metabolism and to increase bone mass in osteoporosis. In women with disseminated mammary carcinoma, Duraxyl 100 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.
It’s a progestin, like any Nandrolone derivative, and is made by removing the carbon atom at the 19th position of the Steran Nucleus of testosterone. However, although it’s a progestin, Nandrolone (regardless of ester) doesn’t produce much of what we could properly call estrogenic side effects. Any side effects from Nandrolone Phenylpropionate would therefore more properly be termed progestenic in nature- as it only converts to estrogen at roughly 20% the rate of testosterone.
Regardless of ester, and water retention not withstanding, we find that all of the characteristics of found in one type of Nandrolone are found in any other. Nandrolone, probably owing to its progestenic nature has the ability to improve collagen synthesis as well as bone mineral content. Clearly this would be a huge benefit to athletes with connective tissue problems or other joint issues, although drug-tested athletes need to avoid Duraxyl 100 because of their detectability in urine for a year to eighteen months after administration. Also, since it is progestin (with slight estrogenic ability), it probably has some very beneficial effects on the immune mediated anti-inflammatory process, thereby soothing joints as well as helping to heal them.
Duraxyl 100 HOW DOES IT WORKS?
Duraxyl 100, and nandrolone in general, has a number of benefits for athletes, it increases levels of serotonergic amines in the brain, these chemicals contribute to aggressive behavior, this could help athletes to train harder and improve speed and power. Duraxyl 100 also increases levels of IGF-1 in muscle tissues. This may be another way that makes nandrolone highly anabolic. Duraxyl 100 also benefits the athlete by increasing the number of androgen receptors (AR) one study showed that Duraxyl 100 given to rats at a dosage of 6 mg/kg of bodyweight combined with muscle functional overload (muscle functional overload gives a similar effect to resistance training) had a 1,300% increase in AR protein concentrations. There is a direct link to muscle growth and AR levels. Duraxyl 100 also seems to be a promising fat loss agent, men given the drug had reduced levels of subcutaneous (under skin) adipose (fat) tissue, visceral (gut) fat loss was not as good however. The fat loss effect seems though to be dose dependant, in one study Duraxyl 100 at a daily dose of 1, 4, or 10 mg per kg of bodyweight the 10 mg dose had the greatest effect on fatloss, thus displaying a dose respondant curve with Duraxyl 100. The more you use, the more results you?ll get, with regards to this drug.
Duraxyl 100 is used to treat anemia by stimulating red blood cell production, and an increase in RBC count can improve endurance during exercise via better lactic acid clearing and oxygen delivery. The blood is also better enabled to carry nutrients to muscle tissue to aid in repair, administration also increases the rate of muscle glycogen repletion after exercise helping the athlete dramatically improve recovery after strenuous physical exercise. Athletes who require a high level of endurance in their chosen sport can benefit from the use of Duraxyl 100. A favorite with bodybuilders who suffer with sore joints, Duraxyl 100 can also improve collagen synthesis, which may improve joint function and alleviate joint pains.
Duraxyl 100 can be highly useful in either "bulking" or "cutting" cycles, and it would seem that diet and dosages are the determining factors of whether a cycle with this drug will be one or the other. 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). Duraxyl 100 can thus be part of a classic bulking cycle. For a cutting cycle Duraxyl 100 is usually be combined with other short-estered injectable anabolic steroids and one of the DHT derived orals such as Stanozolol (winstrol) or oxandrolone (Anavar). Duraxyl 100 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 to the PgR of 60% (3x that of nandrolone). The elevated prolactin, can worsen HPTA insult, often causing the user to spend more money on preventative measures, the combo may also result in a difficult PCT protocol to regain natural testosterone production.
Duraxyl 100 SIDE EFFECTS:
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. More serious side effects include testicular atrophy, impotence and gynecomastia. Duraxyl 100 use has been shown to be safe and easy on the lipid profile, often improving HDL Cholesterol Impotence can be offset by stacking the nandrolone with a higher testosterone. Duraxyl 100 also causes the "shut down" of natural testosterone production. Thus an exogenous source must be provided, the increased prolactin levels from the use of a progestinic steroid contribute to HPTA shut down and testicular atrophy which can be treated with a combination HCG and Bromocriptine. Besides using Bromcriptine to lower prolactin levels, the anti-estrogens fulvestrant or Letrozole on be taken to down regulate the progesterone and estrogen receptor.
