Rapid Mass Gain Catalyst



Simply put, if you’re not consuming more calories than your body is burning, you will not gain mass – you can’t argue with this fact! QUICKMASS works by providing a precise 1010 calories per serving (four scoops) with custom engineered nutrient matrices that set the gold-standard in mass gainers.

  • Made with several sources of Complex Carbs including Sweet Potato, Oat Fiber & Quinoa!
  • Proven 3:1 Carb to Protein Ratio
  • Free of Artificial Colors and Dyes
  • 100% Whole Protein Source with zero Non-Protein Amino Acids

QUICKMASS has ZERO trans fats and contains Coconut oil powder, a valuable source of Medium-Chain Triglycerides. Unlike many other weight gainers that contain carbohydrates that are derived from sugar. QUICKMASS contains only 3g of sugar per scoop! It also contains a blend of carbohydrates including high-molecular weight maltodextrin, sweet potato, quinoa and oat fiber to lengthen nutrient delivery and provide sustained levels of higher energy.



UNIVERSITY REASEARCH-BASED SCIENCE FOR MAXIMUM MASS: QUICKMASS packs 1010 MASS-BUILDING CALORIES into every serving in cold water, no milk required! During one 8-week Gold-Standard (double blind, placebo-controlled) study conducted at California State University, test subjects provided the same calorie content as 2 servings of QUICKMASS per day gained 4.5 times as much fat-free mass and increase chest size by 1 inch.*



QUICKMASS uses 64g of SUSTAINED-RELEASE PROTEIN to BUILD MASS. MASSPRO creates a rapid and sustained delivery of MUSCLE-BUILDING proteins that work continuously all day to RECOVER and GROW. With our precise 3:1 CARB:PROTEIN ratio, you know you are getting the right nutrients to grow! Power up your MUSCLE PROTEIN SYNTHESIS and FUEL your LEAN MASS GAINS!* 3 different forms of protein with high levels of both Essential and Branched Chain Amino acids combine to provide a longer more sustained delivery of protein to help you grow!






SLOW-RELEASE CLEAN-CARB BLEND is critical to provide the fuel your body needs to grow, all day. CARBPLEX absorbs up to 20 times more slowly than sugar providing the ultimate MASS FUEL to fuel your gains! The QUICKMASS carbohydrate blend is powered by long-chain, healthy and complex carbohydrates such as sweet potato rolled oats and quinoa along with scientifically studied and tested carbs like Cyclo-D and Soluble Corn Fiber, a natural prebiotic.






The best thing about QUICKMASS is that YOU DON’T NEED TO ADD MILK! That’s right, while other products add calories that come from milk, all of the calories listed on QUICKMASS come from the product itself.

QUICKMASS is absolutely PERFECT and DELICIOUS with just water! Milk is expensive. Don’t settle for a mass gainer that doesn’t mix with clean, cold, refreshing water.

QUICKMASS is a rapid weight gainer. By adding QUICKMASS to your training program, you can rapidly gain lean body mass. QUICKMASS provides a whopping 1010 calories per serving (four scoops) and 64 grams of high-quality protein in a proven 3-to-1 Carb to Protein ratio. With a stack like that it’s no wonder those who have tried QUICKMASS have raved about how quickly it helped them pack on the lean mass.

Blend, Mix or Shake 1 to 4 rounded scoops (67 g to 267 g) with 4 oz (120 ml) of cold water per scoop.For 4 scoops, 16 oz (500 ml) should be used. Add the water first, then QUICKMASS® when preparing. For best results, it is recommended to take 4 rounded scoops twice daily for an 8-week period. As an option, cold milk can be used instead of water, but it is not required.

There are two ways to supplement with QUICKMASS:

Rapid Mass Gain Phase

Rapid Mass Gain Phase is ideal for those looking to put quality mass on fast.
USAGE: 4 scoops rounded twice daily, take the first serving between your first and second meal; and your second serving immediately following training.

Mass Maintain Phase

The Mass Maintain Phase is ideal for those who have already completed the Rapid Mass Gain Phase and have reached their target weight but now want to maintain their gains.
USAGE: 1 to 2 rounded scoops twice daily, take the first serving between your first and second meal; and your second serving immediately following training.

You can cut back on the serving size however, research indicates to see the same results as the study group experienced at California State University, you should consume two serving sizes of QUICKMASS, which equals 2020 calories. You can definitely reduce the number of scoops depending on your mass gaining goals and due to the exceptional macronutrient profile still benefit heavily from its use.

We suggest that you supplement with QUICKMASS twice a day along with a solid weight training program and diet for at least 8 weeks to experience the true potential QUICKMASS can offer.

A gold standard, eight-week study conducted at California State University on a weight gainer with a nutrient profile equivalent to QUICKMASS showed extremely promising results. Test subjects who consumed the weight gainer daily gained an average of 6.8 lb and total body mass over an 8-week period. This study proves that adding QUICKMASS to your program can help you gain weight like never before!

For optimal results, you should consume 4 scoops rounded twice daily, take the first serving between your first and second meal; and your second serving immediately following training.

QUICKMASS is for anyone who is looking to gain quality, lean muscle. Although it’s extremely popular with bodybuilders and powerlifters, anyone can use QUICKMASS. We have even found it helpful for women who have trouble gaining weight too.

In a GOLD-STANDARD 8-WEEK study performed at California State University, test subjects consuming the nutrient equivalent in 2 servings of QUICKMASS daily, gained an average of 6.8 lbs of Total Body Mass.

If you find 4 scoops too many to consume at once, you can take 2 scoops 4 times a day. On training days, take 2 scoops 4 times a day: 2 scoops upon waking; 2 scoops 1 hour prior to training; 2 scoops after training; and 2 scoops right before bed. On days off: take 2 scoops upon waking; 2 scoops 4 hours later; 2 scoops 4 hours after that; and 2 scoops right before bed.

When you’ve reached your goal weight, you can start to follow the maintenance phase. It is no longer necessary to consume a full 4 scoops a day. You can reduce your serving size to 1 to 2 rounded scoops twice daily, take the first serving between your first and second meal; and your second serving immediately following training.


“I’m a married father working as a mechanic in a busy shop. I don’t have a lot of spare time and wanted to make every workout count. After talking to some bodybuilders it sounded like QUICKMASS was the way to go. I’ve always had trouble gaining weight, so I was extremely impressed with the results I achieved using this product. I never thought I could put on this much lean mass in such a short period of time. I weighed 152 lb and after only 8 weeks, I gained 20 solid pounds. Over the last 8 weeks, I’ve also had huge strength gains. My bench went from 235 lb to an easy 350 lb. I now weigh 172 lb and counting – thanks to lots of clean food and ALLMAX QUICKMASS. Thanks ALLMAX!” – Trevor Campbell

“I never thought 8 ½ months ago I would be almost 40 pounds heavier and more than twice as strong. Before that I was a scrawny 129-pound kid. I had already joined a gym, but didn’t know how to grow. I discovered the importance of having enough calories and protein in my diet to gain weight and strength. I started on a simple 3-day split routine, and my friend gave me some sample packs of ALLMAX ISOFLEX for post-workout shakes. I found that when I started taking ISOFLEX shakes that I would work harder in the gym so I wouldn’t waste the 50+ grams of protein. I began eating more and not using my ectomorph body type as an excuse to be skinny. See before I started making gains I thought that being skinny all my life and always having a high metabolism would ensure that I wouldn’t be able to grow.

“This is a message to all you kids that think you are a hard gainer – if you have a solid nutrition plan and workout schedule you commit to, you will gain muscle. But to the nutrition side, you must consume an excess amount of calories to gain any kind of weight. The reason your weight doesn’t go up is because you don’t consume enough of the right kind of calories. I fixed this problem by drinking a delicious Cookies and Cream serving of QUICKMASS every day, providing my body with 1010 extra calories per serving. The reason I chose ALLMAX supplement line is because they are great tasting products, and they have a big selection of flavors and products, ranging from protein powders to creatine and pre-workout formulas and more.

I know that the taste of some people’s current protein powder leaves them not wanting to use whey, but trust me, Peanut Butter Chocolate ISOFLEX tastes amazing and not just amazing for a protein powder but for a milkshake. This is the main supplement I used to get the necessary protein post-workout protein. I would recommend any new lifter to use safe natural supplements like ALLMAX. With ALLMAX supplements, I become the Teen Transformation of the week on Bodybuilding.com.”

Slater Kirby gain 25 lb of solid muscle:

“Hey, I just wanted to say that I finished your 10 lb tub of QUICKMASS in about a month and I just want to say that I gained a solid 25 lb of muscle. QUICKMASS is the only product that has worked for me…ever! Thanks a lot Bros. It has really helped me bulk up for football.”

QUICKMASS User gained 10 lb of solid muscle and gained 50 to 75% in strength:

“I have tried a bunch of different brands of protein/weight gainer shakes, but by far QUICKMASS is the best! With the other shakes I could only gain 5 pounds max and I had trouble getting the shakes down. They didn’t taste good and it was too much to drink, leaving me bloated and feeling uncomfortable. All that to gain 5 pounds was definitely not worth it!

With QUICKMASS and a regular workout routine, I was able to put on 10 solid pounds and increased my strength 50 to 75%. Before using QUICKMASS, I was in decent shape, but I just was very small, weighing just 136 lb. After one month (approx. 1 bucket of QUICKMASS), I weighed at my highest ever, 146 lb.”

Andrew gained 18 lb of solid muscle:

“Hi again, I would like to say Quickmass is awesome! I’ve gained 18 lb since getting my order. I started at 138, now I’m 156!”

Rob Hackman, London, ON gained 20 lb of solid muscle:

“Along with me, my brother (Rob) also took QUICKMASS. After one month of using QUICKMASS, he actually gained 12 lb, going from a mere 120 lb to 132 lb. With the help of another 2 buckets, he was able to gain another 8 lb (currently weighing 140)

“Not only does QUICKMASS work great, better than anything I’ve ever tried, it tastes amazing! You can’t go wrong with that! Thank you QUICKMASS and ALLMAX for making it easy!”

QUICKMASS User, Vaughan, ON:

“I am 16 and 125 pounds. I am really skinny, but I’ve decided to use QUICKMASS while working out. I am now 127 pounds and I’m still in the first week of using it. QUICKMASS is INCREDIBLE! The taste is AMAZING! Thank you soooo much!” – QUICKMASS User, Vaughan, ON
