I've been using 15 mg of test prop daily for a few weeks now. I rotate between six injection sites. Lab values are right where I want them to be. I am kind of a stoic so I tend to ignore side effects but I finally realized yesterday that all six of my injection sites are achy and/or inflamed and one is downright painful. Has anyone ever heard of someone being allergic to test prop - or more likely the oil base used in test prop? I used test cyp for years with none of these issues. Today I am feeling run down, achy and lethargic - unheard of for me - as if I am fighting something off.
