Finally a protein powder that doesn’t judge me for eating like a bear before hibernation.
I bought this because I’m on a mission to gain weight — not just a little, but enough to make my skinny jeans nervous. GNC Bulk 1340 is like the superhero of protein powders. One scoop and I feel like I could wrestle a buffalo (or at least confidently ask for seconds at dinner). It tastes great, mixes well, and doesn’t make me feel like I’m drinking drywall paste. Bonus: I now have a legitimate excuse to eat more. My metabolism is confused, my fridge is scared, and I’m loving every minute of it. Highly recommend for fellow “hard gainers” who want to bulk without the boredom.

Really gritty

Great taste and solid results
The GNC Pro Performance Bulk 1340 Mass Gainer tastes surprisingly good! It mixes well, especially with milk, and doesn’t leave that chalky texture some gainers have. I’ve noticed steady weight and muscle gain since using it. It’s filling, smooth, and great for after workouts or between meals. Definitely worth it if you’re trying to put on healthy weight!

Not worth the price at all
Not much of a difference in weight gain or muscle I have noticed a gut growing from it though and has build up and dehydration

The package was in good condition but the product seal was opened. This is dangerous and unacceptable.
