## Description

Product 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. Brand Story By

Review: Great Product! Gained 4lbs in first 2 weeks. - OVERVIEW: I've always been at a constant weight for the past 5 years hanging around 150lbs. Before I started taking this about 2 weeks ago, I weighed 150lbs. I was doing one of those Kris Gethin muscle mass workouts for about 2 weeks in as well taking pretty much just Whey as my supplemental protein. I began taking the Pro Complex Gainer twice a day with 1 shake right in the morning and 1 before bed. I found this has helped buffer my entire day with constant protein intake. This is where it helped me the most. I had a hard time hitting those ridiculous 3000 calorie marks while trying to eat just brown rice and chicken, but adding in 2 shakes brought me almost half way there. I ate normally throughout the day as this stuff doesn't sit heavy in your stomach. I found this a huge plus since I hate that bloated sluggish feeling. So that left me with 1800 calories to get to which isn't terribly difficult as I'm eating yogurt, brown rice, nuts, and chicken throughout the day. And on training days, I'll have 1 pre-workout shake and 1 post-workout shake containing protein so I would surely hit my protein marks by this time. TASTE: This is by far the tastiest of the protein drinks I've had without having to mix in fruits and yogurt and what not into it. Double Chocolate flavor is a must. PERFORMANCE: I'm at 154lbs in just 2 weeks and mostly in muscle gains so I'm excited to see where this takes me. COST: This stuff can get costly since I noticed that you supposedly need about 5 regular scoops of what you use from the Whey Protein tub to make up just 1 serving of this stuff! The scoop for this protein is like a SHOVEL. I don't even understand how you can scoop this stuff out and pour it into any cup. So I end up using the extra plastic scoop from my other whey protein to get this stuff into my bottle. Given the large serving size, I'm 3/4 done with my tub so I will likely need to buy the 10lb bag next time.
Review: Gains are great!! - BEST gainer ever!! I really recommend it!! Flavor is great and gains are awesome!dissolves easily ,energy Level is great..I combine it with monohydrate creatine by ON,it’s a great combination and of course with a good diet,works for me,but every body is different,Try to buy specific from the ON store,it is more secure that you going to get what u pay for.

### ⭐⭐⭐⭐⭐ SO GOODD!
*by K***T on June 4, 2025*

Usually never do reviews but this weight gainer is pretty good. I'm 5'7 and started at 149lbs and now I'm at 155/156lbs Pros: -Saw about 8lbs of weight gain over almost a month which is good if you want a lean bulk, if you want to gain weight fast this is not the protein powder for you. -I'm a lot less sore from my workouts. I train as a power lifter and I've noticed significantly decreased DOMS. -minimal bloating and discomfort -The taste is really good. I prefer the vanilla though because it is easier to mix with other flavors. Cons: - Slow weight gain (again not meant to bulk you up fast but slow ,steady, and lean which in the long run is better so you have less fat to cut) -You should weigh your portions, the cup they provide will definitely not get you the serving size.
