40M Ectomorph that has been struggling to gain good healthy weight here. Started taking NutraBio Extreme Mass 10 weeks ago and I already gained 20lbs of healthy weight along with (slightly) improved diet and exercising. Tried dozens of different weight gainers and this one is so far my favorite that has shown best results. Great quality product that mixes well even without using a blender, has good taste (I think very important to be able to drink regularly/daily) - I will be adding this to my daily shake going forward. Vanilla flavor seems to be most versatile for mixing with variety of ingredients (e. g. oats, peanut butter, honey, etc. ) but all three flavors are great.

Totally happy!

I took Creatine + Extreme Mass for six months while lifting every other day and added 25lbs. of muscle. I could have done better if I had been more diligent with my lifting, but I slacked off. I went from 180 to 205 and gained one inch in my waist (36"). That wouldn't have happened if I had worked harder lifting. I'll keep the same routine going forward with my ultimate goal of 10 more pounds. By the way I'm 75 years old and ripped.

I love the product but it has too much sugar and it's a little bit hard for an adult. I have been using it for the past couple of weeks, I hope to see the result soon.
