The ‘Two-Pin’ technique increases sanitation for multiple dose vial users. They draw with the first pin, and then shoot/inject into the body with a new one. This procedure prevents any residual contaminants that may have remained on the drawing pin from being transferred into the body via the injection site. It also makes injection less painful since the drawing needle is necessarily dulled during passage through the rubber stopper atop the vial. A dulled needle increases injection pain because it doesn’t pierce the body as cleanly as an unused one. The protocol below is followed by AAS users who draw from multiple dose vials, but steps 4 - 8 are routinely disregarded by those users who draw from ampoules (also called ampules) and sachets.
"For a drug court program, drug testing is conducted primarily to monitor a defendant’s progress in treatment — to determine whether he or she has been using drugs and, if so, the type and quantity of substances being ingested. The drug test result may be used as a basis for imposing sanctions and/or enhancing treatment services, on the one hand, or reducing treatment service requirements, on the other. Drug test results may also indicate a participant’s progress in reducing drug use when he or she has not eliminated it altogether.
"Although drug test results are frequently reported in terms of 'positive' or 'negative,' in reality, the determination of the presence or absence of a particular drug in the system is not always a black-and-white determination. Ultimately, for a drug court program, a positive or negative result reflects the presence or absence of certain drug metabolites in the sample at a concentration above or below the established cutoff concentration."
Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
