Want to gaing 18lbs over 2 months - how?

[Silent Method]

How can I put on 18 lbs without all if it coming on like a train. I do not want anyone to see me blow up overnight. They will know I am on juice. What is the best way to do this?

18 pounds in 8 weeks, if muscle gains, is a shitload of weight in no time at all. Sounds like you want to have your cake and eat it too...
