How much should a 5 - 8 Medium frame man weigh to not look skinny ?

Right now I only weigh like 139-140 pounds.. and I just feel too skinny... So I bought two 12 pound bags of Serious Mass and I'm going to take a full serving everyday for a month to see what it does. ( extra 1,300 calories a day or so ).

I'm expecting to get up to 150 pounds or close to that... I lift weights regularly but I don't eat enough so I guess its kind of pointless unless I have the protein and calories at the same time...

A surplus of 1300 calories a day? This is a way too much. As of basic and safe rule, start with 500 surplus. Don't rely on gainer as with mass there will be lot of water weight. Supplements can never replace the real diet, they jare for giving you an extra push when you exhaust your natural ability.

Also, 1300 calories a day as a beginner, you might get stretch marks due to a sudden increase in body growth.
