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.
Great reading Colin, just saved me from wasting money on a quick cure out the internet. I feel pain for 1 think i know exacly when and how i damaged this the way,i am a professional massage therapist since 1996, and the 6 people a day for a one hour treatment 6 days a week for sure is not anyway you just won your self 1 or 2 massage treatment whenever you visit Estoril makes much sense to me all you said back have a rather broad and deep experience in bodywork… just to tell you that you might like to start to look at exercise in terms of quality as opposed to quantity…. thanks so much Colin José 00351 964725666
