Please evaluate diet, training & recovery before you start looking at steroids. "Need a boost" is your body saying whatever you are doing right now ain't workin. That means the whole scope of your lifestyle - are you eating well? Are you sleeping well? Are you getting enough sleep? Are you stressed all the time? Are you getting into the gym?
Throwing in steroids is a much bigger step w/ greater consequences and probably nothing like what you thought you were going to get out of it if 1) you don't understand steroid use (meaning SHE, not you telling her stuff you read online - HER body, HER results, HER sides...) and 2) your lifestyle (all dimensions as listed above) have not already been reviewed and optimized.
Please provide more detail.
