QUADS - With muscles this large, you need to do multiple daily injections. Where in the biceps you use 1ml per head per day to begin with, on quads you need to start with 1ml per site, 7 sites per quad. That is to avoid the `lumpy' look and keep the quad uniform. Again, to keep the natural look of the thigh, you should inject in the `peak' of the outer quad, injecting along the crest. If the teardrop is lacking, then just inject straight into it, rotating sites daily. I personally don't recommend quad shots, especially teardrop, due to the very high amount of nerves in the area.
