Gold Standard Gainer vs Pro Gainer

Gold Standard Gainer has a 203 gram serving size (2 scoops) compared to 165 grams (1 scoop) with Pro Gainer. Within this larger serving size, Gold Standard Gainer offers 20% more calories, due to the 27 grams more carbohydrates and 4 grams more fats that it contains. The fibre content is also higher in Gold Standard Gainer compared to Pro Gainer, offering 9 grams per serve versus 5 grams, respectively. 


gold standard gainer vs pro gainerThe protein content is comparable between the two mass gainer powders, though Pro Gainer contains an extra 5 grams per serve at 60 grams of protein. Pro Gainer contains a broad-spectrum multivitamin and mineral complex that is not found in Gold Standard Gainer, which is helpful for supporting overall nutritional status.


However, Gold Standard Gainer contains a quality whole-foods carbohydrate mix, which includes oat flour, pea starch, potato starch and lactose or milk sugar (and some maltodextrin). The carbohydrate and sugars contained in Pro Gainer are derived exclusively from Maltodextrin and lactose.


Both Gainers contain medium chain triglyceries (MCTs) to promote energy and training intensity. Pro Gainer contains 200mg less sodium and 20mg less cholesterol per serve, making it a more heart-healthy choice. In terms of the protein blends, Gold Standard Gainer contains primarily whey protein in the form of isolate, concentrate and some hydrolysed isolate, with some casein contained in the milk protein isolate. However, Pro Gainer contains both egg, casein and whey protein sources, making it suitable for anyone in need of a more sustained release product.


Both products contain an abundance of calories and protein, making them effective for any mass gains program. However, if you prefer whole foods sourced calories with a lower glycemic index, Gold Standard Gainer is a more suitable choice. However, Pro Gainer is a more heart-healthy option which also offers a greater sustained-release effect.
