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.
They are g2g for sure. I've used Tren enanthate, testosterone enanthate, sustanon and clenbuterol from Alpha Pharma. Gains with the injectable steroids were really great. Nothing to complain about and almost no pip (all ampoules). However the clen (Astralean 40 mcg) I used was really underdosed, perhaps a bad batch or something. I had to take 4 pills at once to feel something. With other clens My hands were shaking with only 2 pills of 20 mcg. They also have a site to check if the products you have are legit or not. They all have a nice seal above their serial numbers
