Even still, it's pretty heavy. But if you're confident then go at it and best of luck. Just a warning, 2 phase cycles are not easy to do. You have to be very, very disciplined with your diet and stick to your plan. I haven't seen anyone successfully do one that isnt a serious competitor. It usually turns out to be one or the other. Usually a bulk because people can't come to diet. But if you can do, all the power to you. Keep us updated.
With regards to your liver, just take milk thistle throughout (wont help much) and make sure you take PLENTY of time off before your next cycle.
