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.
For bulking, go with a Nitrocut/Testofuel/Creatine. Nitrocut is a non-stimulant pre workout, Testofuel is a natural testosterone booster, and Creatine gives your muscles the power to push more weight. When it’s time to cut, switch out the creatine for a non-stimulant weight loss supplement. Try Quadralean .
