Thin build men to gaining mass the right way, tips and programs that actually work. Trust me I was a thin build man of 60kg's until the age of 32 no matter what I done. Proved and tested this and was able to gain mass without the aid of personal coaches. Went too gaining 25kg's in one year of body frame size and muscle. Of course it all comes up to the commitment of the individual. Many years have passed and still keeping my body build. Very Happy.
