Product Information


Animal M-Stak™ - The Hardgainer's Stack

Some will say Animal M-Stak is the perfect hardgainer's pack. Others will say it's a plateau buster in a can. Whatever you call it, Animal M-Stak flat out works, thanks to its unique nutrient-partitioning effects and its ability to help promote anabolism via protein synthesis, nitrogen retention, while reducing muscle wasting (catabolism).

Animal M-Stak's potency starts with its unique Natural Flavone/Sterone Complex. These natural flavones and sterones act as nutrient-partitioning agents to help shuttle needed calories specifically to lean mass instead of toward body fat deposition. Remember, it's not just about eating but actually drawing the nutrients to the muscles where you want them, in an efficient manner that will ultimately build new size.

Animal M-Stak is also stacked with a mega potent Anti-Catabolic Amino Complex. These aminos work to stimulate protein synthesis at the level of translation initiation through non-hormonal signal transduction by manipulating key muscle growth regulators mTOR, PKB, p70s6k, 4E-BP1, FOXO and MAFbx. These are crucial components for optimizing while body protein balance and are facilitated via the leucine-heavy amino blend so integral to the Animal M-Stak formula.

The synergy between the natural flavones and sterones is central to the effectiveness of the Animal M-Stak. But the growth potential of this formula does not stop there. Animal M-Stak's Anabolic Adaptogens work to give you the ability to cope with the stresses of lifting and daily life by helping to reduce Cortisol and other damaging, muscle-wasting catabolic agents. Anabolic Adaptogens work to ensure the anabolic status of your internal environment, allowing you to more readily pack on mass. Animal M-Stak also contains cutting-edge insulin potentiators, which work to ensure that your body will utilize ultra anabolic insulin effectively and efficiently.

But Animal M-Stak is more than just a "hardgainer's" supplement. It may be suitable for drug-tested athletes. Further, Animal M-Stak contains a potent energy blend designed to propel you through your most intense gym sessions. Beyond that, the Animal M-Stak formula is tied together by the M-Factor absorption complex intended to maximize nutrient utilization to ensure that all of the powerful elements of the Animal M-Stak formula are processed to maximum efficacy.

Animal M-Stak is just the supplement you've been looking for, for natural gains. It's a non-hormonal anabolic formula capable of enhancing performance and promoting the necessary environment for you to add lean mass. If you feel you're training has been missing something, you're right. Animal M-Stak is here, turning "hardgainers" into "hard" gainers.

Hardcore product
Finally! Something that has put only hardcore muscle mass on me and added pounds and pounds to all my maxes. I'm 155 pounds now deadlifting three times my body weight after only months after breaking my wrist! This product helped me bounce back and is awesome!!!!!
A must have for serious lifters
Takes a little to get used to taking so many pills but works very well especially when you stack it with the animal stak. I love their products worth the money

totally awesome!
im 29 years old and been working out for about 4 years. i wrote a review for animal stak because i take animal stak and m-stak together because i noticed they worked best together. all i can say is that this thing is awesome. I've used all type of supplements and always come back to the truth! get on the animal train of fall behind! get bigger faster. thats all i have to say.

My Number One So Far
If you know your body and what needs and what it can benefit from, then this stuff is for you! I wouldn't say it's really a supplement pack for beginners and nor is it for abusers (would have little or zero effect for those of you). Be smart and follow the directions on the label.

It allowed me to keep a steady workout and know when I wouldn't benefit from doing anymore reps. Eveyday was an improvement with ideal recovery time. I just finished my first cycle this morning, and my body is kind of tired from the level stress I've maintained for the past 3 weeks. I'm definitely taking a week off.. overall my body has achieved optimum endurance and strength. I know I'm nowhere near peaking, and I never have to choose running over lifting or vice versa. It allows longer intervals between workouts without sacrificing those hard earned gains.

I'm going to try another Animal product (TEST pak), but this my no fail go to stak pak! I'd like to say that I can control my emotions (specifically agression and hostility), so a cycle with TEST would be very interesting. Next time I choose M-Stak I'm going to use it with Jack3d. A good powdered preworkout seems necessary with this to begin hard and finish strong. I wouldn't dare use Jack3d with a test booster since I never use them. I would never try Jack3d with anything I've never used due to its potency. I'd probably turn into a wild animal.. lol, sorry.. Good name for a sports nutrition company.

I'm 21, perfect health, 190lbs, 5'7", eat healthy, and was already in great shape.. so I'm pretty ideal for this product. I'll post a review for TEST at the end of next month. Take care of yourselves!

Outstanding Product
Animal M-STACK has added a new intensity to my workouts. I'm burning fat and getting stronger by the day. Can't recommend this product enough for someone looking to cut while maintaining their strength.

Huge Gains
I've taken this product every day around noon with lunch, and I've seen huge gains in mass in the few weeks I've been using it. Of course my bulking diet is helping with that, but I'm also getting significant increases in strength.

Great Product. Just what the Dr. Ordered
I have used this product for 2 weeks now and wow what a difference it has made. I combine with C4 before workout and i feel like i am unstoppable. My trainer noticed a big difference in my lifting and recovery time. This is by far one of the best products that i have used to give me that added edge that i was looking for.
