Here is what i would consider.. you are having a more difficult time gaining weight being 5'10" and only 155... obviously your diet is going to need to be changed and you are going to need to start getting in a lot more calories... so mk677 makes sense to get your appetite going but you would definitely want to stack with it.. also, keep in mind to really get the most out of 677 you want to go a good 6 months on it... you can go less but you will never get all that you should out of it running it too short.. i would go with mk2866 and acp-105 as your other two... you can get size, strength, lean and dry muscle, endurance, healing and acp will really harden up muscles and give more definition as well.. you never want to try to gain too much too fast because it will destroy your joints, ligaments and tendons... when you are already that far undersized, and you put hormones into your body along with fixing your diet, it can be very very rapid, even with compounds that generally dont add that type of size... so you cant go insane with what you run but still want to get the job done in the right manner...
