Each shake provides ample supplemental protein, carbs, vitamins and minerals to build on the amount you're getting through a balanced diet of food. Use PRO Gainer as your post-workout recovery shake and/or high-protein meal between meals.

## Questions & Answers

**Q: what's the difference between this one and serious mass?**
A: This is much easier to digest, healthier, better protein and nutrients and only one scoop compared to 4 which becomes chalky and hard to drink. This tastes a lot better than serious mass and is much easier to drink overall. I drank this with reduced fat milk for 3-4 months straight and gained 20 lbs. of course I was also tracking and lifting weights, but this helped a ton to get those extra 800 calories I needed that I couldn’t obtain through meals and a lot of cooking.

**Q: I'm most concerned about it causing gas.  Any comments?**
A: NO Gas with vanilla custard and i give this to my 98 yr old MOTHER who weight 80 LBS as a supplement !! SHE Wd get it cuase shes in a wheelchair- Just finished a 10 lb bag.. DO need to drink WATER cuase HIGH protein can stop u up.. I also add ice cream to it:) tastes great! Good stuff- Doc approved! Shes in GREAT shape + he does Labs on her al the time.

**Q: If this is so good, it makes me wonder why it has twice the protein and is $45 cheaper per 10lb bag than Gold Standard - the same company.**
A: Which Gold Standard are you looking at?  This is a lean weight gainer vs protein vs bulking weight gainer.  Sometimes the wholesalers give us deals if we purchase a large amount at a time.  Some sellers (myself included) will discount the price in relationship with the "cost" associated with the product I sell.

**Q: Which is better for bulk muscle mass: serious mass or pro gainer**
A: Serious Mass is a high-calorie gainer with 1,250 calories and 60 grams of protein per serving. PRO Gainer is a high-protein gainer with 60 grams of protein per serving at 650 calories.
