Hyper-Anabolic Mass Gainer
Built By Science. Driven By Obsession. Elevated Through Innovation.

Proven Ingredients. Proven Doses. Clinical Quality. Real Science. Real Results.

Re-Built Mass XP is a hyper-anabolic, high-protein, high-calorie mass gainer targeted to engorge muscles for the ultimate mass power and size subjects seek. Featuring a high-leucine protein blend and an advanced creatine complex, it is scientifically designed for maximum effect.

MAXIMUM MUSCLE SUPPORT: Features clinically studied components shown to improve muscle size, stamina, and strength. Loaded with 60g of protein to fuel ripped muscles and 140g of high-quality carbohydrates to support massive gains.
ANABOLIC FUEL: With clinically dosed whey and leucine blend shown to trigger anabolic recovery, improve post-training anabolic response, boost post-training insulin for anabolic recovery, and impact key genes in muscle tissue required for muscle growth, recovery and repair.
  • Carbs: Includes high-quality complex carbohydrates to fuel high-intensity exercise.
  • Protein: Supplies 60g of high-quality whey protein, including whey protein isolate, whey protein concentrate, calcium caseinate, and hydrolyzed whey protein. Adequate amounts of protein are crucial to supporting subjects’ muscles and keeping a positive nitrogen balance.
  • Fat: Features a prime combination of MCTs, canola, and CLA powders.
Re-Built Mass XP contains clinically studied components shown to improve muscle size, performance and strength.
  • Features a complex carbohydrate blend to fuel high-intensity exercise.
  • Built with an Advanced Creatine Complex, including two varieties of creatine and a blend of creatine precursors to fuel the body’s natural synthesis of creatine.
  • Included within this anabolic matrix is the clinically studied 20 / 6.2 whey-Leucine blend demonstrated to increase muscle size and performance.
  • Clinically studied Opuntia Extract provides additional anabolic support. When combined with Leucine post-exercise, Opuntia Extract has been shown to positively modulate insulin response. Insulin is an important signaling molecule to further support anabolic recovery.
  • Collectively, this formula is scientifically designed to enhance muscle size, strength, performance and power.

Highly Recommend!
This was the first mass gainer I've taken in a while, and I must say I'm impressed. i'm going to stick with this product when I want to bulk! Highly recommend this to those that wish to bulk up! The Strawberry flavor is delish

Very very impressed! Best time to buy is when they have big sales going on in the store
This is the best protein I've ever taken! Packed on plenty of muscle and strength. Instead of mixing 3 scoops, I break it down and mix 1.5 scoops in the am, and 1.5 after I workout. I mix mine with a spoonful of peanut butter! Taste a whole lot better and add more protein.

Have tried the old beyond raw and this one tastes much better! The consistency makes it mix very well every time. Recommend this product and will continue to use.

Works for me
I have tried many weight gainers and they always made me feel bloated & gave me explosive gas. Not this one, it works great and i have already gained 10 lbs since taking this/ Yes it's very pricey for only 11 servings, but will continue since it really works for me. The taste isn't that bad, the Strawberry tastes like Strawberry Ensure.

Not sure about vanilla but cookies and cream isn't too bad! Working great on me.

Worst protein mass gainer I've ever used. I've never had any stomach problems taking protein shakes and mass gainers, until I started taking this. The flavor is just awful, and 59.99 for 11 servings is ridiculous!! Waste of my money. Going back to for products.
