A few months. I highly doubt.
It will depend on your size now, whether you're a fast gainer and diet, let alone the work out dedication.
That guy has thick arms, i'm guessing 16 inches. It takes about a year to gain 1 inch of pure muscle on your upper arms. The average mans arms are 13 inches around. It takes progressively longer the bigger you get, 13 to 14 is quicker than 14 to 15 etc. So if you had 14 inch arms, 2 inches on them will take about 1 year minimum i think.
So even if you just wanted his size arms, i'd say you'd most likely look at a year.
