Product name: Nandrolone Decanoate
Synonym: Decadurabolin;19-Nortestoterone decanoate
CAS No.: 360-70-3
Reference Standard: USP28
Appearance: White Or White-off Crystalline Powder
deca is an anabolic steroid. deca is most commonly sold commercially as its decanoate ester (DecaDurabolin eubolin, retabolil) and less commonly a phenylpropionate ester(Durabolin[. deca decanoate is used in the treatment of osteoporosis in postmenopausal women at a dose of 50 mg every three weeks. It is also used for some aplastic anemias.
The positive effects of the drug include muscle growth, appetite stimulation and increased red blood cell production and bone density.Clinical studies have shown it to be effective in treating anaemia, osteoporosis and some forms ofneoplasia including breast cancer, and also acts as a progestinbased contraceptive. For these reasons,in the United States deca received FDA approval in 1983.
Because deca is not broken down into DHT, the deleterious effects common to most anabolic steroids on the scalp, skin, and prostate are lessened to a degree; but is rather broken down to the much weaker androgen dihydrodeca. The lack of alkylation on the 17α-carbon drastically reduces the drug's liver toxicity. Estrogenic effects resulting from reaction with aromatase are also reduced due to lessened enzyme interaction, but effects such as gynaecomastiaand reduced libido still occur in larger doses because of other mechanisms. Other sideeffects of abuse can include erectile dysfunction and cardiovascular damage, as well as several ailments resulting from the drug's effect of lowering levels ofluteinizing hormone through negative feedback. Erectile dysfunction is attributed to the weaker action of dihydrodeca in the penis since dihydrotestosterone is a known sexual modulator.
deca use is directly detectable in hair or indirectly detectable in urine by testing for the presence of 19norandrosterone, a metabolite. The International Olympic Committee has set a limit of 2.0 μg/L of 19norandrosterone in urine as the upper limit, beyond which an athlete is suspected of doping. In the largest deca study performed on 621 athletes at the 1998 Nagano Olympic Games, no athlete tested over 0.4 μg/L. 19Norandrosterone was identified as a trace contaminant in commercial preparations of androstenedione, which until 2004 was available without a prescription as a dietary supplement in the U.S.
A number of deca cases in athletics occurred in 1999, which included high profile athletes such as Merlene Ottey, Dieter Baumann and Linford Christie. However, the following year the detection method for deca at the time was proved to be faulty. Mark Richardson, a British Olympic relay runner who tested positive for the substance, gave a significant amount of urine samples in a controlled environment and delivered a positive test for the drug, demonstrating that false positives could occur, which led to an overhaul of his competitive ban.
Heavy consumption of the essential amino acid lysine has allegedly shown false positives in some and was cited by Americanshotputter C. J. Hunter as the reason for his positive test, though in 2004 he admitted to a federal grand jury that he had injected deca. A possible cause of incorrect urine test results is the presence of metabolites from other anabolic steroids, though modern urinalysis can usually determine the exact steroid used by analyzing the ratio of the two remaining deca metabolites. As a result of the numerous overturned verdicts, the testing procedure was reviewed by UK Sport. On October 5, 2007, fivetime gold medalist for track and field Marion Jones admitted to use of the drug, and was sentenced to six months in jail for lying to a federal grand jury in 2000.
Mass spectrometry is also used to detect small samples of deca in urine samples, as it has a unique molar mass.
|How to Prepare for Your First Steroid Cycle|
A steroid cycle is the length of time in which a person uses steroids. The time of use is referred to an 'on cycle' and when a person decides to take time off between steroid cycles, this period is known as an 'off cycle'.
Typically, someone just starting out on their first steroid cycle will use just two compounds together, over a period of no more than 8 weeks. This is to ensure that they don't use more steroids than they need to and put too much strain on their body. It's also to help them assess whether steroids are right for them or not. The choice to use steroids should never be undertaken lightly, and so if you do decide to go ahead it's important to prepare as much as you can.
The first and best thing you can do before you start using steroids is to read as much information as you possibly can. Look online, visit some of the popular steroid and bodybuilding websites, and talk to your friends at the gym who have steroid experience. You will need to research which compounds are best to use, the pros and cons of taking oral vs injectable steroids, and how to manage any potential side effects. You may also wish to read up on what kind of results you should expect to see and when, as this will help you to manage your expectations.
Organizing Your Meal Plan
As a committed athlete you should already have a meal plan in place that's designed to help you increase muscle mass and lower your body fat percentage, whilst providing you with all the right nutrition you need to stay healthy. If not, now's the time to really concentrate on getting your nutrition sorted out, as you'll need to ensure that your body is healthy enough to cope with receiving artificial testosterone. Two of the side effects of taking steroids is decreased liver function and increased water retention, so think about including some foods that will help with these two problems.
Planning Your Workout
Steroids don't work on their own so you will need to keep training in order to see results. However, you don't want to over train as this can result in muscle tears that might take weeks - if not months - to heal and can severely impede your workout. So remember to go slow at first, but make sure you're sticking to a regular routine. Resist the urge to increase your weights for the first week or two. You may feel ready, but it's important you give your muscles time to catch up.
