Optimum Nutrition Pro Gainer will help you put on size, 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. PRO Gainer is a high-protein formula delivering calories that count during recovery. Each shake provides ample amounts of 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 a high-protein meal between meals.

Optimum Nutrition Pro Gainer features:

  • 60g of protein per scoop

Many athletes who are aiming to put on muscle size, tend to either have high metabolisms, weak appetites, or have on the run lifestyles, that make consuming sufficient calories through food alone, a challenge. Pro Complex Gainer provides 650 calories per serve, which adds plenty of clean calories to a hard-gainers diet.

  • 10/10 Banana Cream

    1st time buying this gainer (I usually get the gold one,but i need something with more protein & GAINZ) and already the flavour Banana Cream is my new fave shake of all time and just within the week the Gains are coming through. Also you will want to buy the big size cause it's pretty filling, tasteful & affordable!!
  • 10/10 Banana Cream

    Great gainer I have gone through two of these already banana cream as I love bananas or vanilla as it mixes with everything. Not as thick as other gainers and easy to consume! Mixes well does get bit clumpy but just chuck in the steel mixer thing that helps.

    I love On Nutrition Pro complex gainer. It is a right mix of protein and carbs, it will NOT put on extra fat and very good for lean muscle building. The bulking has been very gradual for me. 3 kg in 3 months and I take just one serving per day. Best part is how easily it mixes and the mild taste. Only down side is the cost. It is more expensive than other gainers.
  • I am taking this since almost 6 months + as I need to keep my intake high due to workload and workout. Perfect at 4am before going to milk the girls to replace a meal. Love the banana cream taste!
  • This is in my opinion the BEST gainer on the planet. It's the only gainer I will take. It's not full of sugary fillers it has real complex carbs as the base for most of it's calories. It really helps you pack the weight on and doesn't effect performance like other gainers. Also it tastes AMAZING.
  • Mixes well and testes very good and feels very light after consumption. Will recommend for gainers who wish to gain clean !! Very good product and very good price at Sprint ! Thanks guys
  • Really good gainer! put on 4kg in the first 5lb. triple choc tastes amazing and isn't thick like other gainers. mixes well and doesn't make you feel bloated. would definitely recommend to any hard gainers.
