Trenbolone also has progestagenic affects. Tren, as we’ve previously said, possesses strong androgenic properties. Tren is not known in the anabolic steroid community to cause gyno. However, it would be interesting to observe many cycles of anabolic steroids which include a heavily aromatizing steroid with trenbolone. No doubt many athletes have combined tren and testosterone with miraculous results. It would be interesting to note amongst these individuals if they have ever developed gyno when combining the drugs, but not when taking them alone. Remember, progesterone sensitizes the body to estrogen, so whatever estrogen is available will be more likely to act out and cause the negative effects we know estrogen is responsible for. The moral of the story is to be cautious and knowledgeable about the drugs you are combining. Actually, that should be true whether you are 21 and raving at a night club on e, or a responsible individual, through with your party stage, and maximizing your safe use of anabolic steroids. Drug synergy can be an amazingly useful tool when used for maximal gain, but can be very unfortunate and even dangerous if multiple negative properties of drugs are allowed to gather inside the body. We will talk more about the specifics of drug synergy in another section.
If you're going to use any injectable gear, then of course you're going to need some "darts." You can pick up syringes at your local pharmacy unless your state has certain restrictions. Also, you can purchase needles online. Just do a little searching around and you'll find several places that'll hook you up. Syringes will run you around 50 cents apiece. Note that it'll be more difficult to obtain needles (at least from the larger, more "legit" companies) if you live in California and Illinois. You'll usually need a doctor's prescription in those states. Still, if you look around enough, you can get what you need.
Heavy consumption of the essential amino acid lysine (as indicated in the treatment of cold sores) has allegedly shown false positives in some and was cited by American shotputter C. J. Hunter as the reason for his positive test, though in 2004 he admitted to a federal grand jury that he had injected nandrolone.  A possible cause of incorrect urine test results is the presence of metabolites from other AAS, though modern urinalysis can usually determine the exact AAS used by analyzing the ratio of the two remaining nandrolone metabolites. As a result of the numerous overturned verdicts, the testing procedure was reviewed by UK Sport . On October 5, 2007, three-time Olympic 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.
