I also use the same easy touch ones for hgh and other water based compounds that need small volume and inject either subq or small sites. For higher volume or deeper IM i use either BD or Nipro usually, depending on what I found in stock or in the size I needed when ordering. Typically 27g 1/2" or 5/8" for smaller sites, and 25g 1" for larger. I used to use 1.5" but find that 1" works well for me at my current leanness. I used to draw with bigger needles (eg 18g or 21g) to make it go faster but after getting some leaky tops after too many punctures, I switched to drawing with either 25g (GSO) or 27g (MCT) and my stoppers dont fall apart now. I always warm my vials on a coffee warmer before drawing
