I am gonna start a cycle in about a month and I wanna know what are the main differences between the two. I have tried NPP before, but I don't like the fact that you have to pin every two days and with deca that is not the case. Is water retention worse with deca that with NPP? My goal is a very modest gain of about five pounds of muscle, so I think NPP would give me a better look than Deca. I wanna hear from somebody who has tried both to know how they feel about this.
