Geez, I guess anything is possible, but those would be phenomenal numbers if achieved.
Easy to gain 10-12 pounds and lose fat on this stack, especially if you are a novice. Easy doesn't mean you will, just that those numbers fall in line with what other people have been able to achieve.
Do you have 20 pounds of fat to lose? You can't lose fat for others, you know.
I say it is possable if you have a very good diet. Everything all depends on your diet so you have to know what works for you. I have heard of people doing it before so I don't see why it is not possable for you. Keep us posted buddy
