*I DON'T WORK OUT* - 3 full meals + 3 shakes = I GAINED 40 POUNDS (MOSTLY FAT) IN 2 MONTHS
Chris Y✓ Verified Purchase•September 1, 2023
I wrote a VERY detailed review of my experience with this product, and it was NOT for laughs nor an attempt at trolling yet Amazon or ON decided to take it down. This is a SERIOUS REVIEW FROM MY VERY REAL EXPERIENCE!!!
****BE WARNED!!! THIS STUFF IS *PACKED* WITH WHAT IS BASICALLY SUGAR (SUCRALOSE!) I HONESTLY THOUGHT I MIGHT HAVE GOTTEN DIABETES DUE TO HOW FAST I PACKED ON WEIGHT.*****
I have always been skinny and tall (5'11" , 160lbs) for as long as I can remember. Even eating junk food, snacking constantly, drinking soda, etc. did not help me gain weight. I was eating at least 2200 calories a day while NOT moving. This was towards the end of COVID - still sitting all day working from home. I ordered this (I've tried this product 4-5 times before, but I never stuck to it or drank it how I did this time - I decided to drink 2 FULL SCOOPS WITH MILK+HONEY+PB as "dessert" right after EVERY meal).
Fast forward ~2 months ....
I've stuck to my regimen of drinking 2 full scoops with milk, honey, and PB after EVERY meal (3x a day), every day for ~60 days. I didn't notice much in the first month ... but almost all within the last couple of weeks, it was like someone put a bicycle pump in me (specifically my stomach areas and chin area) and pumped it up.. like Michelin Man status. I stepped on the scale and my eyes almost popped out when I saw 201 pounds. At this point my stomach was literally like I was 5 months pregnant while standing up - when sitting down I could move my stomach rolls around. The tees I used to wear when I was skinny (160 pounds) were size XL TALL and hung comfortably off my shoulders/chest, but now my stomach popping out made a very noticeable stomach outline on whatever clothes I wore.
THIS STUFF REALLY WORKS - I SERIOUSLY GAINED SOME SERIOUS MASS. If you have the body type of skinny or skinny fat with a high metabolism and you want to know if you can gain weight AND not go to the gym, YES YOU CAN JUST DRINK THIS 3x A DAY (ADD TO YOUR REGULAR MEALS) and you will literally pack on the mass.. BUT AGAIN, you are downing a BUNCH OF SUCRALOSE.....
To this day, I am still ALWAYS hovering around 197 - 204 pounds - I started working out because having a stomach that you could make faces with was not the business. Having this fat while working out is definitely a benefit since it will turn into muscle quicker.
I HAVE ORDERED WHEY PROTEIN NOW AND WILL BE TRYING TO TURN THIS BULK INTO MUSCLE.

Made in USA, quality stuff, quality taste, packed full of vitamins, calories, and protein! YUM! I like the vanilla flavor, and it blends smoothly without clumps in the blender or even in a shaker cup.
Taste Good !

I was iffy about getting it because I kept seeing people say it has a bad taste or after taste and it does not. I can say the first try it did but that's because I used tap water but ever since after I use bottle water (poland spring). I ordered vanilla and it taste just like a milkshake :)) !! So good I finish it in less than 10minutes and be wanting more lol. And yes i feel my weight coming in.
Gain weight in a healthy way

My weight had dropped from a healthy 110 lbs ( 5'2" petite female ) down to 82 lbs over 4 years due to a crazy thyroid and lung disease. I had no"cushion" and broke my hip in a motorcycle drop. I began using MASS in January 2023, but less than instructed. I used only 2 small coffee-scoop's in a smoothie. ( ice cream, milk, peanut butter, frozen fruit + MASS ). Had one everyday, or added the 2 small scoops to oatmeal. 7 months later, in July 2023, I was up to 94 lbs. Couldn't be happier. Up to 3 small scoops per shake now and gaining about 1 lb every 2 weeks. Highly recommend for weight gain and muscle mass.
