Stay toned without sacrificing muscle

Use a very small calorie deficit over a longer timeframe. The larger the deficit, the more muscle wasting you'll likely experience. Steroids will, of course, cut down on atrophy and depending on your experience level and body-fat you could even gain muscle while losing fat. Hard to say more without additional details.

Thanks — that's really helpful and informative. I'm on a Test cycle right now, so hopefully that will make a difference.

Shoot for about 1 gram of protein per pound of bodyweight. Follow a solid strength-training program. Keep the calorie deficit modest, and aim for roughly eight hours of sleep per night. That should cover most of it. If you're very lean you might still shed some muscle, but usually it's easier to regain than when you first gained it. Also, anabolics help reduce muscle loss.

Thanks for the advice!

That's exactly what I was thinking.
