Great Protein

My experience with Serious Mass has been nothing but great. Constantly pushing my body to the limits requires some serious fuel to rebuild it, & Serious Mass is getting the job done for me.

Mixes well, tastes great, but not very many servings

Great product. I liked the taste and the nutrition facts speak for themselves, but it's tough when it only has 8 servings per container (16 if you split it). But overall I'd still rate 5 stars because it's helping me reach my weight goals.

Overall the taste is good

Overall the taste is good and for the price you get a good size tub of weightgainer. A couple minor gripes is that the scoop size is not like your Typical scoop—it’s like a shovel. Won’t easily fit into most shaker cups which makes For some tricky, awkward mixing. Also the powder is so fine that the slightest sharp movement will result in powder all over yourself! All in all it tastes good; not the best for easy quick mixing but the price is pretty fair for the quantity. Worth trying once
