MASS-TECH® features 63g of protein, which supplies fast-, medium-, and slow-digesting proteins. The multi-phase protein system provides critical amino acids to the body at varying speeds for extended delivery of amino acids in the blood.

13g BCAAs

The formula’s protein dose supplies a massive 13g of BCAAs and 6.5g of L-Leucine, which help fuel your skeletal muscles, preserve muscle glycogen stores, and help to reduce the amount of protein breakdown.*


The powerful formula now delivers a massive 840 calories derived from high-quality protein and quickly digested carbohydrates. It is the most versatile weight gainer available, which can be taken once daily or split into two separate half servings.

132g CARBS

Supplies 132g of carbohydrates through a multi-phase carb complex to spike insulin within a normal range, quickly shuttling creatine into the muscle, and promote muscle glycogen replenishment, helping to put the body into an anabolic state.*


Unlike other leading gainers that contain little to no creatine, MASS-TECH® delivers a 10g clinically validated dose to increase strength fast.*


An 8-week study examined the addition of 2,000 calories (over 2,000 calories are found in 2 servings of MASS-TECH® each mixed with 2 cups of skim milk) to a high-protein diet containing approximately 2,300 calories and a weightlifting program. On average, subjects gained 6.8 lbs. of mass while control subjects gained 1.3 lbs.

Mass-Tech 8-Week Study


In the same study noted above, test subjects also gained massive size where it matters most – directly on their chest and arms. They gained 1.2 inches on their chest and 0.5 inches on their arms versus the control group, which only added 0.5 inches and 0.2 inches.

Mass-Tech 8-Week Study


MASS-TECH® is a powerful weight-gain formula developed with key massbuilding compounds that are shown in research to help increase size, strength and overall mass.*

I'd have to admit, I'm really not a huge *** fan of muscle Tech technology Labs. I also have to admit, that this is the best tasting protein powder I've come across in years. Especially for a bulking agent. Taste very smooth, blends well with milk or water. Vanilla is my top tier, following via cookies & cream🥛🤗

Mass tech Big Liar, (has only 12.6gr protein not 63gr) They saying 63 grams of protein per 5scoops 5 scoops ÷ by 63g = 12.6 grams per scoop. The scoop its roughly 51 grams checked (quite big scoop, almost double then the others). they boost too much on ads (like no1) but the quality is not as expected. Thank you

This is the best mass gainer that I have ever tried, tried different flavors, most of all I liked milk chocolate, also really like the presence of enough creatine monohydrate. Highly recommend this product (my overall rating is 10)

Overall a decent product that does what it says. That’s because it recommends 5 scoops of this thing x2 times daily to achieve the marketed gains. So any gainer taken in such high quantities would do that. Tastes better with milk. Not good for people with a weak stomach. The contents are clean with no fillers and artificial products. It has a good ratio of bccas and one might not need an additional amino supplement. Good product for price. I have yet to see the results as it’s only been 2 weeks I started it.

I actually bought this on amazon but reading the reviews on here is what convinced me to buy. The Birthday Cake flavor was rated highly so I chose it. It smells like lucky charms when you open the tub, but the flavor is like metallic mashed potatoes. I have to blend this with two bananas to be able to choke it down. The ingredients are good and I'm sure this does positive things for your body, so if you can stomach the taste I would say go ahead and order.

My daily intake was 3000 calories , I bought this product to raise my daily intake but it ended taking less than 2000 calories a day , it makes you feel so filled although that I was taking three scoops a day which is less than the whole daily service , I think if I take 5 scoops ( the whole service ) I will not eat anything at the day , for me it’s the first and the last time to use it .

I've been looking for a good tasting protein with lots of carbs/calories to help with the winter bulk. Really like this stuff, very good taste and solid protein.
