I don't do it naturally because I'm a hardgainer that realizes natural doesn't work for everyone. I'd rather not torture myself for the same (or more than likely weaker) results when I can simply get a head start putting on mass this way. I eat every 3 hours. Healthy high cal high protein foods, less fat....3500 cals a day...which should put on 1lb per week according to my BMR.... but it doesnt work. Too highly active 3 days of the week too. So that hurts with my metabolism. I work out a lot, just not for mass.
