Rapid Mass Gain Catalyst



We have redesigned QUICKMASS to build on what was already an industry leading, technically superior formula. We’ve kept the same proven, researched based, 1010 calorie/60g protein per serving and we still have a superior complex carb blend to fuel your gains but now we’ve made it even better.

  • Now with 60% Less Sugar! Only 3g per Scoop (Or 12g per Serving – Less than 5%!)
  • Made with several sources of Complex Carbs including Sweet Potato, Oat Fiber & Quinoa!
  • New & Improved Flavor Technology: The Best Tasting QUICKMASS we’ve ever made!
  • Proven 3:1 Carb to Protein Ratio

QUICKMASS is the world’s first and only calorie-activated mass gainer. It also 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 is the world’s first and only calorie-activated mass gainer. Only team ALLMAX can bring you this exclusive compound! In fact, 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 60g 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 ration, 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!






8 HR. 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 Vitafiber.











Protein Absorption Agents with Enzymatic Nutrient Activators triggering rapid gains in lean body mass. Patented Cinnulin PF dramatically improves nutrient and creatine absorption. The result you absorb the highest quality nutrients effectively to turn calories into MASS.*


Our 60g protein yield is 100% sourced from only the very best protein source – pure milk exclusively from U.S. dairy farmers. Our CARBPLEX carb blend has been improved to add healthier, long chain, complex carbs and it now has 60% less sugar. Even our absorption complex has been upgraded to improve absorption. While we were at it, we created the 5 best tasting flavors you’ll ever get in a mass gainer. QUICKMASS – a truly superior mass gainer, in every way.

This means consuming a huge amount of quality calories. 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.

QUICKMASS is a scientifically formulated mass builder based on California State University research and is designed to help even the hardest gainer pack on lean mass quickly. This gold standard, 8-week, double blind, placebo controlled study showed an increase in chest size of 1 inch and 4.5 times as much lean muscle mass than the placebo group.

QUICKMASS accomplishes this by combining a scientifically proven calorie level with a new calorie activation system called NP5™ Technology. Every angle of the QUICKMASS formula has been custom designed with the sole objective of delivering the strongest, most potent mass gainer in existence today! We at ALLMAX Nutrition feel we have accomplished our mission – you be the judge!

  • Provides an added 2020 scientifically engineered calories a day for colossal muscle growth (based on 2 servings per day)
  • Provides a unique delivery matrix of 60 grams of sustained-release protein with 29 of those grams from Essential Amino Acids and of that nearly 14 grams of those are growth stimulating BCAAs – all of which are naturally occurring within the protein!
  • Glycemically balanced carbohydrate matrix prolongs insulin release to maintain positive nitrogen retention
  • A precise 3:1 CARB:PROTEIN ratio as recommended by top sports nutrition scientists

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 60 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.

Servings should be combined with 4 oz of cold water per scoop and mixed thoroughly in a blender. Mix 8 oz (or 1 cup) of water per 1 scoop of QUICKMASS (16 oz of water with 4 scoops or 2 scoops with 8 oz of water). For optimum mass gain results, it is recommended to consume QUICKMASS 4 scoops (1 Serving) twice daily for an 8-week period.

There are two ways to supplement with QUICKMASS:

Rapid Mass Gain Phase™

Four scoops of QUICKMASS twice a day. Take the first serving between your first and second meal and your second serving immediately following training. Rapid Mass Gain Phase is ideal for those looking to put quality lean mass on fast.

Mass Maintain Phase™

Two scoops of QUICKMASS twice a day. Take the first serving between your first and second meal and your second serving immediately following training. 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.

You can cut back on the serving size and still get the superior macronutrient profile of QUICKMASS without getting a full 1010 calories. 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.

If you’re consuming an additional 2020 calories a day, you should start to experience rapid changes to your body. However, we suggest that you supplement with QUICKMASS twice a day along with a solid weight training program 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 6.6 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!

QUICKMASS has an excellent flavor and consistency. It mixes very well with water in a blender or in a shaker cup. While we do recommend water, if you prefer, you can blend QUICKMASS with milk. If you’re using milk or extra ingredients, it will increase the thickness and you may need additional liquid.

For optimal results, you should consume QUICKMASS twice a day. One serving in the morning and the second serving after you workout or before you go to bed. Taking less than the suggested serving size will not guarantee the same results.

NP5 is a groundbreaking technology unique to QUICKMASS that unlocks calorie potential via calorie activation. The calorie activation technology made up of protein absorption agents with enzymatic nutrient activators that allow the body to utilize calories more efficiently, thereby triggering rapid gains in lean body mass. Patented Cinnulin PF dramatically improves nutrient and creatine absorption. The result: you absorb the highest quality nutrients effectively to turn calories into mass.

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.

Like every ALLMAX product, QUICKMASS has been lab tested, and certified to guarantee satisfaction. There aren’t many other companies that stand behind the quality of our products like we do.

Although results differ from person to person, test subjects using pre-market QUICKMASS prototypes were gaining quite a bit of weight in as little as 10 days. Take Nelson Dasilva for example, an IFBB professional bodybuilder who thought he would never breakthrough a dreaded mass building plateau. That was until he added QUICKMASS into his program and added an amazing 10 lb of lean mass in as little as 13 days. Try QUICKMASS for yourself and experience how much weight you can gain as quickly as possible.

    1. Calorie Activator: QUICKMASS is the world’s first and only calorie-activated mass gainer. Only team ALLMAX can bring you this patent- pending exclusive compound!
    2. Reduced Sugars: NOW WITH 60% LESS SUGAR! Only 3g per scoop. Many other weight gainers contain carbohydrates that are derived from sugar. QUICKMASS contains an exclusive carbohydrate complex called Carb-Plex, an 8-HR slow release clean carb blend. This carbohydrate blend exclusive to QUICKMASS 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 Vitafiber.
    3. Zero Trans Fats: The saturated fat content in many other weight gainers is usually way too high. Not only does QUICKMASS have zero trans fats but it also contains Coconut Oil powder, a valuable source of Medium-Chain Triglycerides.
    4. High Quality Protein: QUICKMASS uses 60g of sustained-release protein to build lean quality 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.
    5. Real Science: QUICKMASS is supported by clinical research based out of California State University.

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 or 2 scoops twice a day – upon waking and after training and on days off – upon waking and right before bed.

“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
