for injecting - 22g, 23g, 25g - for oil-based steroids, 27g, 29g - for insulin, HCG, HGH, and some water-based steroids. 21g-25g for some lower quality types of winny or suspension, higher quality versions can use a smaller needle generally.
22g and 23g are fine for glutes and quads. 25g is preferred for the smaller muscles such as delts, biceps, triceps, etc.
What length needles should I use?
Most people can get by with a 1" needle, but if you have a higher percentage of bodyfat or are just plain big you should use a 1.5" needle to insure that you get deep into the muscle. You should only use a 1.5" needle for glutes, or if you have huge quads. For smaller muscle groups, 1" is the most common, although some people like to use a 5/8".
How many ccs can I shoot in one place?
It depends on how big you are. A general guideline is 1cc for delts, 2cc for quads, and up to 3ccs for glutes. Some do more, some do less......it all depends. After a cycle or two, you will know what your body can handle. If you are injecting into other muscles such as biceps, triceps, or calves, it's best to start off with a small volume and work your way up.
