i work at gnc and i love when i give people mass gainers and they come back telling me how much they gained weight and they love what i gave them. depending on how much you wanna gain, i like Mass Tech Extreme 2000 from Muscletech. its 2,000 calories for 6 scoops and 80g of protein. i always tell customers to split the serving size up and take 2 scoops three times a day. [here’s the link](https://www.muscletech.com/products/mass-tech-extreme-2000) another gainer i like is Optimum Nutrition Pro Gainer. it’s 1 scoop for 650 calories, 60g of protein which is super lean! [here’s the link](https://www.gnc.com/on/demandware.store/Sites-GNC2-Site/default/DeepLinking-Link?destination=com.gnc.app%3A%2F%2Fproduct%2F352609%3Fsource%3Dgnc-marketing-email%26fallbackToStore%3Dtrue) Even though i work at gnc, i normally don’t promote their products like other locations BUT i do like their Mass XXX formula for the gym. it’s a little more professional with added amino acids, some creatine, plus MyoTor which is a muscle builder plus strength. the jar says “increase muscle mass within 2 weeks and increase lean muscle mass within 40% fewest sets” and customers came back to tell me they did in fact see differences!!!

ON Gold also just blends so well it’s a nice fine powder. Agreed it’s top tier.

I just bought (2) 10lb bags of ON Gold for <$200

I don't know what you mean by "clean" but Optimum Nutrition Gold is pretty much the gold standard.

Our Costco almost always has the Kirkland, ON, and Orgain plant powders for a great deal. Look for the 'Aussie Bites' in the snack section, the ingredients / protein is pretty crazy for the small bites.

Hi. I have tried GNC and ON and didn't like both. How is MB in terms of quality ? Heard the taste is good.

Doesn't mix as well as ON, messes with my stomach, and doesn't taste as well either. I bought a bag of the Kirkland powder to try, boy it was tough to get through. The wife and kids didn't really like and were more than happy to go back to ON.

I’ve been happy to drink either, but I prefer ON because it has a stronger chocolate flavor. The Kirkland does live up to its flavor name because it does have a creamier flavor than the ON. I buy whatever is cheaper per oz at the time.
