Sure, it's been the program where I've made the most consistent gains in size and strength. When I've tried higher volume workouts where you do multi sets/exercises per bodypart (e.g., Max-OT) I usually stall at a lower weight/size. With Doggcrapp I just focus on that one rest/pause set per exercise, and focus on building strength, and I get better size gains. I have always used Doggcrapp when I've been my biggest, both on and off gear.
The only downside to DC is that the lower volume does give you somewhat of a softer/bulky look, but what I do is do DC to gain size and strength, then increase volume to maintain and improve density/hardness.
Overall DC is a more effective and fun way to train IMO. Lower volume, higher intensity, higher frequency of workouts (and "growth phases") due to lower volume.
