TweetIs this your first cycle?
What are your stats?
As for cutting, deca probably isn't the ideal choice simply because it can cause some bloat. But at 300mg it shouldn't be bad at all. Deca and Winny work well together, and although your doses are somewhat light, you don't need all that much to hold onto muscle while dieting.
You can 'cut' on just about any steroid. Becoming lean has more to do with diet than anything else.
