Probably your basic test/deca/dbol stack. 3grams test, 1gram deca, 100-150mg/day dbol. 8-12iu/day GH, 10iu's slin 3x per day. There's your bulker. Cutting... primo, eq, tren, masteron, still plenty of test, GH, IGF, T3, clen, amphetamines, winny, halo, anavar, diuretics. Probably leaving out half a dozen at least, not even including ancilliaries, but you get the idea. They don't do much different than we do, they just have great genetics, stay on all year, and use huge-ass doses.
