Number one why's your cycle so short? Number two what's your age weight, diet, training and cycle experience (I'm guessing very limited) Number three.You can't even think about a cycle without correct supports, diet, training and pct is a MUST and you can't expect to rely on your source to help you, fair enough if he's experienced and you trust him you count him in on some of your research but research at the end of the day is your job as you are the one that is putting foreign substances in your body and believe me you don't want to get it wrong as the implications can make you very ill and can even be fatal in some cases. Do your research and don't think about starting without pct, you should be looking at Clomid, Nolvadex and I'm not sure that you'll need Hcg for such a short cycle, here go to this website and you'll get all the information you'll ever need.
