Ive recently started my first ever cycle and have a concern. I make sure to keep real clean but i think im having a reaction of some sort. The injection site (the shoulders) have gotten a little itchy and the skin looks a little irritated. I was wondering if it is common for people to have a dermotological reaction to products that are not detrimental to your health or the effectiveness of the workouts. It feels sort of like when you get a mosquito bite and scratch it until the skin gets warm and hard but this is happening in a large area of my shoulder. I have no discoloring as far as bruising or what i think an infectiuon would look like. Its just red and a little warm. The skin is very hard though where it is swolen. id really appreciate a reply, any info is good. Thanks
