Three days ago my arms and legs broke out with a severe rash/hives. The only thing I changed last week was my brand of test prop and the addition of 20mg msten per day. The propiobloic is made with ethyl oleate, I've heard people can be allergic to this. I've also heard of people getting hives from msten. The rash is not at injection site it is all over arms and legs. Extremely itchy
