We have the Organic Mass Gainer and the Vegan Protein for those looking to gain lean muscle without putting on the extra fat. I had the same problem as you which got me started on this path. I ran cross country and track from 9-17 so when i graduated i was 6'0 and 155. I have long arms and legs so i look even skinnier. After wasting hundred of dollars on a gym membership, whey, casein, mass gainer, preworkouts and trying a test booster and still being skinny i decided to start looking into the naturals and found that real food provides way more benefits for body building than dead whey proteins. Alot of supplements are nothing but scams. As a hard gainer I had to workout intensely and consistently as well as being consistent with my diet, but i went from 155 to 200lbs in 12 months and I went from being one of the weakest dudes around to being stronger than all my friends who have been lifting weight for years, went to the military, play sports or martial arts. I stopped using weights period and started doing purely bodyweight workouts at the park. Dips, pull ups, push ups, leg raises, wipers on the BARS with many different variations. My grip strength improved in a week and every week i watched the definition of my body get more and more ripped. I have to wait for my stomach to "wake up" to eat also but i started making high protein smoothies in the mornings using the Mass gainer powder and that helped me get those calories in early because you need that meal, you don't want to gorge in one meal. I usually make the smoothies with organic or natural peanut butter, no hydrogenated oils or sugar.
Here are your keys to success
1. Diet. You must eat more and you must eat more of high quality foods, that where the mass gainer and vegan protein powder will help you out, its nothing but spinach, kale ,amaranth, steel cut oats and various other herbs in concentrated form so you are literally getting thousands of micro nutrients with every serving.
2.Workout. Go bodyweight and drop the weights. I can give you a beginners routine for working out on bars for free if you like. Workouts usually only take 30 mins.
3. Don't focus on MACRO-nutrients. These companies always speak about the macro nutrients in their products because they know that the micro nutrients they are composed of are toxic or inferior. Micro nutrients are what people should be focused on, you cannot understand carbs,fats and proteins without understanding micro nutrients first.
