For all the guys that just wanna put on weight with the test hunger just eat high calorie meals. The 5 time world strongest man says a calorie is calorie no matter how u look at it clean or dirty. Dirtys usually have more so if your too thin thats the way to start it all off. I found that after my long test cycle I used b12 to keep the appetite goin kept all my weight after 2 months off just lost some strength. But yea it worked for me so just my advice for the ectomorphs that just cant do it.
