Within a week your dick is going to get more active, but you aren't really going to see anything for a few weeks on that dose. Like others have said, you are going to gain a little water and look a bit "fuller", but not by very much. That is a very low dose if you are interested in actually gaining mass. You will get a little stronger and have better workouts, but don't expect anything crazy.
As Lurker said, the leaner you are the faster you will notice something. If you are a little chubby, you probably won't notice much at all. This is why you see so many guys doubting their gear is real, if you're not lean you aren't going to notice anything for a few weeks. If you're like 8-10% BF, you will see a difference pretty quickly.
If you have low T and really need this for medical reasons, you will feel a good boost in energy after a 1-2 weeks.
