You can bulk AND cut on pRetty much anything. It's all in your diet. Personally I like to go for an all out bulk either whole cycle and cut after post cycle therapy (pct) and I'm recovered or if it's summer time I bulk for 8-10 wks an cut the last 4-6 while on. You can bulk on test alone, test/deca, test/tren and you can cut on em to, it's all about diet.
