Product Information



Hyper-Anabolic Mass Gainer
Built By Science. Driven By Obsession. Elevated Through Innovation.
If it's on our labels, then it's in our bottles. The ultimate gainer for mass, power and size.*
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.

Tastes bad and haven't seen any gains. All the carbs seem to be sourced from sugars, not a complex carb in sight!

Lost weight with this product
Tasted good and mixed well but I did not see any results. I expected to at least gain water weight from the creatine that is in there, but that didn't happen. Used it with the recommended 3 scoops a day for a month (I had to buy a second one) and I've actually lost weight in that time. I just don't think there are quality ingredients in here.

Works as advertised
Great product. Take with three cups of whole milk. During football season I lost 30 lbs and couldn’t stop the weight loss. Started this product and gain it all back in just a few months but even more muscle mass then before hoping to keep gaining and stop unwanted weight loss in season I’ll report back.

Good Stuff!
Just started using this product a few days ago so I can’t speak on the gains yet, but as far as the taste goes it isn’t bad. I got the vanilla flavor and it kind of reminds me of marshmallows. The price isn’t terrible either if you think about it because each serving size is 3-4 scoops of a normal protein powder. I decided to half the serving after the gym and the other half I make into a delicious ice cream at night before bed!

BEST ANSWER: 3 Scoops with 16 oz of water after your workout, if you workout at night have it 3-5 hours before going to bed. but because of the 16g of BCAA and high protein it really helps with the gym aftermath and fuels your muscles.
