P: Honestly bro I'm concerned for you. The cycle looks good. I would follow thx9000 advice and head to anabolicfitness store and get some r-ala and liver detox. Sure you will more than likely be fine, but why do damage when you don't have too? It's a good habit to get into.
It's impossible to say how much your going to gain. If your less advanced you will gain more vise versa because you are bellow your genetic potential. If you are platued, you may see 15lbs after the water shakes off. Make sure you add weight every week, eat then eat some more!! Good luck.
