Update: So I talked to my coach and he believes that my body is reacting to certain chemicals that I'm injecting. Whether it's the compound itself or the BA in the oil. He said when this happens your body releases histamines to combat the foreign chemical in your body if you're sensitive to it. He told me to rest it and move the injections to my delt and put both compounds in one injection. He said if it continues then we can cut back on the dosage for the primobolan which seems to be the compound giving me issues. He said not to massage or heat it and take a antihistamine and keep it elevated
