How you bulk will be more about the diet than what test you use. You can "bulk" on test E and gain a ton of weight or you can cut down and keep it even, even leading right in to a contest. Manage estrogen and focus on a clean diet and you can do whatever you want with Test E or Cyp. Either would be my first suggestion. They are easier to use with 2x wk and tend to be less painful than prop. Also use an AI like arom or adex while using any form of test, to control estrogen levels
