It must be borne in mind that not everybody who does cycles is seeking mass or any weight gain at all. Some are merely looking to lose body fat and define and harden their physiques. Some are just looking to enhance speed and/or strength so that they perform better at certain sports/tasks. I've seen plenty of people who were pretty lean do cycles to get extra shredded and vascular. People do cycles for various reasons and gains in mass/bulk isn't always one of those reasons. Just remember, there are many goals tp pursue in this sport. Everybody will not share the same goals.
