A friend just started using some Test Cyp 300 from a well known UG lab. Each shot has been very painful. So he e-mailed the UG lab & asked them if it was due to the high BA or high mg concentration. He was told that some people get pain from ethyl oleate. EO is supposed to make injections painless, but for some people, he expalined, it does the opposite & it causes them a lot of sorness at the inj site? Is this true, or is this an excuse for high BA content or bad UG homebrew technique?
