3 out of 5 rating for 100% Whey Protein Gold Standard (5 lb)
ON 100% Gold Standard is a very popular brand of protein. In terms of market share, I'm sure it's basically between ON 100% Gold Standard and BSN Syntha-6. In a vacuum, ON's protein is a whey blend of whey protein isolate, whey protein concentrate, and whey. Basically, it means this sits between a whey protein isolate and a whey protein concentrate in terms of quality. As such, its amino profile is pretty standard but slightly better than the competition cutting their whey with soy protein.
On the other hand, there are definitely problems with this protein worth mentioning. The main one is their flavoring. I have tried chocolate, vanilla, and cookies and cream. Their chocolate flavor was a cheap, run-of-the-mill type flavoring, whereas the other two were anywhere from disgusting to nauseating. No protein is good enough to warrant such poor flavoring. In addition, this protein mixes very poorly, and in my experience is the worst, EAS protein being the worst.
O/N 100% Gold Standard benefits from its popularity and is available at almost any supplement store, and being a decent quality protein it is often a go-to for many. I like that it has few carbs and fats, an important thing to me, so I would chose it over Syntha-6, for instance. But the flavor is bad, and honestly it's not competitively priced, so if someone has the alternative, I would shop online for other options.
