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.
In March 2011, China's Ministry of Agriculture said the government would launch a one-year crackdown on illegal additives in pig feed, after a subsidiary of Shuanghui Group , China's largest meat producer, was exposed for using clenbuterol-contaminated pork in its meat products. A total of 72 people in central Henan Province, where Shuanghui is based, were taken into police custody for allegedly producing, selling or using clenbuterol.  The situation has dramatically improved in China since September 2011, when a ban of clenbuterol was announced by China’s Ministry of Agriculture. 
Anaphylaxis (anaphylactic shock) occurs when the body’s immune system overreacts to a substance, such as a food item. It is an unpredictable condition that can be life threatening. EpiPen is an adrenaline auto-injector used for the acute treatment of anaphylactic shock or severe allergic reactions to allergens, . insect bites or foods. Meda has received a label extension for EpiPen and the product is now also intended for immediate administration in patients who are determined to be at increased risk of anaphylaxis (including patients with a history of anaphylactic reactions). People at risk of anaphylactic shock should always carry an adrenaline injector. The at-risk indication is further endorsed by the new guidelines of the European Academy of Allergy and Clinical Immunology (EAACI).
