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. LEARN MORE ABOUT THE INGREDIENTS:
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.

Great Flavor
Gave it a three for great taste in the chocolate flavor. But did not see results in 2 weeks of use.

I’m currently in highschool football and once I started fluently taking this I made crazy gains every time I stepped in the weight room , this is worth every penny , taste is alright as well.

Big price tag, meh.
Good taste but the shakes are chalky. The product seems to be working as i feel my recovery time is getting quicker. Horrible gas though! I drink it before my workout because of the high carb content but it keeps me running to the bathroom. Price is too much, won't be using this again

Great taste and good gaining results but gives you gas
Vanilla flavor taste great. I mix it with outmeal and a little cinnamon for flavor and to add heartiness. It gives me a lot of gas and I seem to be having blood flow issues... a friend of mine told me to drink more water then I already do so that’s where I’m at right now

So far so good
Good product but gives you the farts the rest of the day. Don't use on days when you plan on having "relations" with a lady.

Not worth it
I bought this to try something new. i was intrigued by this have BCAA and Creatin in it, and it was only a little more than the ProBuilder weight gainer i usually buy. Its really not worth it, i find it harder to mix, thick and chalky and you end up drinking these massive shakes that leave me with a gut ache and burbs the rest of the day. I will be going back to Probuilder.
