The main difference is usually that Mass products contain significant amounts of carbohydrates (mostly simple but also some complex). After realizing that as much as 40% of the weight of Mass shake mixes go to simple sugars like Dextrose, and another 25% to complex carbs, I moved on to normal protein shakes.

Serious Mass probably also includes things like Creatine and added Glutamine. These have been shown to increase mass building but see if Protein Optimum includes them. They are readily available supplements at most health stores which sell bodybuilding nutrition. I would definitely recommend sticking to the Protein and maybe added some sucrose to a post-workout shake yourself. Get the extra calories from things like meat and whole foods which will be better for you anyways. Finally, using Mass products is not recommended for longer than a month or two at a time due to the huge amounts of simple carbs consumed in a short period of time – its like drinking sugar with added starch and some protein.

edit – the reason I use Protein over Mass is simply a cost-benefit ratio. Serving sizes on Mass drinks usually recommend up to 4 large scoops both on resting days and workout days, costing you much more money in the long run. If money is not an issue, Mass drinks are premixed and have well-balanced carb ratios.

i say chocolate is the best flavour!
but u have to also eat lots of real food to gain mass.. not just whey

and u need one gram of protein for each pound u weigh

your muscles wont show

if you cant drink the shakes then have a high fiber diet like whole grain bread its also got 4.6g of protien each loaf.

also dont forget to eat carbohydrates because the help to absorb protien and fiber. but dont eat too much fatty foods (as you all ppl know it).

please answer mine

I suggest visiting http://www.bodybuilding.com as they ahve a big supplement store and detailed reviews of all there products. You can also learn a lot about training to build muscles and the nutrition principles that go along side it. Remember bulking up is 50% Diet 30% Rest and 20% Training. But if any of those things arent right you will never reach your potential.

I ahve no affiliation to the above website by the way I ahve jsut learnt a lot from the time i have been a member on the forums there…

However, I’m going to give you another suggestion – Muscle Gauge Nutrition is a new company with a pure whey protein isolate – all the bad stuff filtered out – so it has less carbs and no whey protein concentrate (milk sugars / lactose… gives me gas) like ON. It’s also cheaper, and tastes great. So check into that.

But all in all, you cannot go wrong with ON 100% Whey, so thank your friend. My favorites are Extreme Milk Chocolate and Chocolate Malt. Buy em online much cheaper than at the local store.

And is Weider Creatine monohydrate the best thing to get big muscles?

If you’re referring to Weider Mega Mass, then that is a weight gainer. If you’re trying to slim down, weight gainer is NOT for you! On the other hand, Optimum Nutrition Whey Protein is basic protein with very low fat and almost no carbohydrates. to recap…

Mega Mass- help the skinny guy gain weight
ON Whey Protein- protein supplement

As for creatine, micronized creatine powder is the most effective creatine on the market. regardless if you’re trying to gain weight or lose weight, creatine will help you pack on more lean muscles while keeping body fat storage at a minimal.

here’s a sample study on creatine but you can find a lot more simply by googling "creatine".
