In that pic I'm about 176ish. It was taken last year after the East Coast MuscleMania Championships. I'm 5'9". As far as gaining mass naturally I have had some luck with Biotest Norandro spray (if you consider that natural). In case you plan on competing, the ANBC and MuscleMania events allow it but the WNBF has banned andro products. I also recently started using Parrillo's CapTri MCT oil for extra calories (I take in ~3800 a day. I found that I get too fat when I go up to 4000). Unfortunately the biggest thing I've learned in over 7 years of drug-free training is patience. It takes a long time but I think you can count on at least 5-7 lbs a year, which might not seem like much but over time adds up. Just stick with it.
