## Description

Putting on size requires a balance of heavy training and quality nutrition. Because everyone's a little different, some have a harder time packing on muscle than others. Optimum Nutrition Gold Standard Pro Gainer is a high-protein formula delivering calories that count during recovery. Each shake provides ample supplemental protein, carbs, vitamins and minerals to build on the amount you're getting through a balanced diet of food. Use Pro Gainer as your post-workout recovery shake and/or high-protein meal between meals.

Review: Excellent Protein for Clean Bulking - Once again, Optimum Nutrition has a winner. To give you an idea of my lifestyle so you can make a comparison, my style of weight-lifting, eating, etc. is more of a "clean-bulking" program. Many will say the concept of the clean bulk is a myth, but I've done it. Is it perfect? Nah, but it works for me. I watch my diet all the time but am no calorie-counting zealot. I exercise every day of the week with five weight lifting sessions and three half-hour interval training cardio sessions (one day is combined of course). I am 5'6" and weigh 138 lbs with about 7% body fat. I am no expert on fitness but I've made it to where I am and I'm proud of it. So this review won't be the most scientific post on desertcart. First off, this is a GAINER protein. I will say that again because it merits repeating. GAINER. Despite it being visible in gigantic green letters on the package, and in the name, and in the description, I am sure some people managed to glaze over this. This is a higher calorie protein while being lower in fat, sugars, etc. so lean mass can be put on. You will put on some great muscle growth if used appropriately with exercise and proper diet. Despite the fact it's a lean gainer, some loss in definition is inevitable. Not all of those calories will go straight towards building muscle mass alone. I have been using this protein since November 2013 and I have seen some great improvements in my muscle gains and my strength shot through the roof. I am sure having the extra calories from the protein to increase muscle growth attributed to those results. Now I did experience some minor loss in definition with this protein since it is after all a GAINER; even with my constant clean diet not all of the calories went straight to my muscles some of it inevitably went to my fat reserves, particularly around the mid-section of course, but the loss in tone was minor. All in all I am thrilled with the results that this protein gave me and how much it bulked up my muscles with such little change to my "aesthetics" so to speak. The protein tastes fine. I am so sick of seeing "THIS PROTEIN DOESN'T TASTE LIKE CANDY. ONE STAR. THIS IS GROSS DO NOT BUY." If you want a candy like taste then go eat chocolate. This is a protein. If it has all the sugars and flavor additives then guess what? It defeats the purpose. Is it the best tasting one I've had? No, but I don't really care. It did it's job and that's what matters. I highly recommend this protein if you're looking to increase muscle mass without adding as much "other mass" AKA lean mass. The price is also a steal for 10 lbs. Pro Tip: If you open the box they ship it in with a knife, be careful. I learned the hard way.
Review: Up 30lbs and counting! - If you're like me, you are probably a male between the ages of 17 and 28 and have a REAAALLY difficult time putting on weight. You have probably tried other weight gainers and have been frustrated by one of the following: poor mixability leading to chunky globs of powder that are a nightmare to swallow, terrible flavoring that makes you want to shed tears at the realization of how much money you spent on a sack of god-awful tasting powder, or of course, a product in which you see little if any results from. I've been there. Keyword: been. This describes me before I found ON Pro Gainer. I am 6 feet tall and have always clocked in at about 165-175lbs. Well, in August of 2015 I had a surgery which put me on a long road of recovery. Not only was I in pain, but I completely lost my appetite and began dropping weight quickly. By the beginning of October, I was dipping down to 155lbs. So I searched for mass gainers, and stumbled across this product. While the price tag was a bit more daunting than I would usually take a gamble on, the amount of protein and calories packed into each scoop (however heaping it need be) was enticing, so I gave it a try. Now it's the end of March (7 months later) and I am currently sitting at 186lbs. Of course I've adjusted my diet so I eat more food than I previously did, but much of my gains can be attributed to the use of this product post-workout. What's even more surprising is I only use the product 3-4 times a week! It is much, much easier to keep up a workout routine when you have a good tasting shake to look forward to after you're done. I absolutely demolish the shakes I make with this powder because it is so tasty and satisfying after going hard in the gym. I use bananas, peanut butter, a big scoop of powder, creatine and whole milk, and the shakes turn out super smooth and delicious. My strength gains have shot up, and my body no longer looks like it's in starvation mode. Stop being like the old me; buy this product and stick to a gym routine and you will absolutely see increases in your strength and mass.

### ⭐⭐⭐⭐⭐ Mixes wonderfully. Not chalky/Sandy
*by F***O on March 19, 2026*

Got this for my husband as he’s been looking for a heavier protein powder as well as to gain some weight. The scoop is massive HOWEVER my husband swears it’s one of the best protein powders he’s ever had. He said it mixes beautifully no clumping so sandy texture just pure chocolate goodness. Hit doesn’t leave you with that extremely stuffed feeling at all he says. We bought the 10lb bag will update on results after he finishes the bag.
