New customer for life

I've had a problem with gaining weight my whole life (39yo) man and recently I had tried this product and went from 98lbs to 120lbs in 2 months I don't follow the recommended dose and only use 1/2 a scoop daily once sometimes 2 times a day but omg I had to order the bigger container as I have found this product to be very helpful. I do not experience any bloating or discomfort of any sort as I have with others I've tried. I am a home health aide and exercise regularly so I am also seeing definition in my muscles that I am now putting on. I am sharing this product with family and friends struggling with weight gain and watching as they too experience the positive impact this product has on the physical body.

GREAT PRODUCT HIGHLY RECOMMEND!!!

I ordered this two days prior to my weight gain journey and it came literally 8 oclock in the morning on sunday. It was sitting at the door step TWO DAYS after i ordered it. Omg if wouldve ordered it off of amazon, id probably still be waiting for it. Anyways, ive been using this for the past two weeks and its been working great for me :) i use 2 full scoops, 3 cups of milk, 2 bananas and a tad bit of chocolate syrup before my workout

Good taste

I just started using the product I hope it helps me keep my weight I previously gained from a pregnancy, I just had my baby so I’m trying to keep some of the weight on since in the past I’ve never been able to gain and just lost all my other pregnancy weight.
