Tweetany help or advice would be great here. my "rat" started ifg1-lr3 8 days ago at 50 mcg per day. he is injecting one bicep one day and the other the next. the first 6 days were pain free with no real sides, but for some reason the last two each bicep has gotten EXTREMELY sore and the injection site has a red patch as if the substance hasnt dissolved. My rat was suppose to work arms today and would like to but the soreness is enough im not sure. Anyone know what is going on or have any advice? is this normal?
