Not sure how to avoid a bruise if you bruise easily. I have only bruised twice in 2 1/2 rounds. One thing that I suggest differently though is after you have the needle in you should gently release the fat before injecting. I was told by a nurse that if you continue to pinch that you are creating a pressure against the injection and not letting it disperse properly. Some of the hcg could also leak back out. You might also try the smallest diabetic needles. They are only 5/16 in instead of 1/2 in. They are my favorite. You can probably pick them up at Walmart if your state allows purchasing without a prescription. I buy mine online at calvetsupply.com. They are the exact same ones packaged the same and are very cheap from them. They also usually ship fast.
