Any good pro-hormone pre workout will do. Along with a lot of food and at least a half gallon of water a day you should do well.
I've found that ZMA at night before bedtime on an empty stomach speeds recovery like nothing else. Also Designer Whey has a great
new protein on the market. It breaks down slower so you don't have the usual protein spike and dropoff. Drink a scoop or two 45 minutes after a workout anytime in the afternoon and right before bed 20 after popping that ZMA and you are ready to grow.
Creatine is overrated. All your 'growth' is only increased water volume in your muscles. Stop taking it... and shrink. Get dehydrated... and you will shrink. Take it or leave it I say.
