I have a hard time believing its the steroids because the body rejects external hormone use until it builds up in the blood plasma then it accepts it as its own basically.
I can't imagine two long ester compounds causing such effects in only two injections. A more probable explanation could be you are allergic to the solution used to mix the hormones (ie. the solvent) or maybe your source is not the best and there are impurities within the hormone that are causing your body to react negatively.
