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.

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.

the missing link in your workout
I took this stuff while deployed in the middle east and it turned me in to a maniac in the gym. All Animal products are solid and this is no exception. More gains after 1 three week cycle than the previous 3 months of working out. Took it with a pre-workout drink and almost passed out from a headrush, so i don't reccomend taking it with anything but a good post workout protien shake

Fanatastic Product
Amazing product for Mass and Strength gains. Very important that you eat a lot of quality protein while taking this product to ensure that you get everything you can out of taking M Stak.

First Impression - Good Product
I Started taking them about an hour before lifting to get a feel for them from the biggest (Brown) to smallest (Red) every 5-10 mins I would take another etc..., when I got to last Blue one I had a lot of energy so I waited 20 mins deciding if I should take Red one (the energy pill), Which I did, I felt like an overcharged battery wanting to explode and a bit light headed that lasted all thru the workout up till half of the day , (next time I will not use the Red one which is optional / I recommend only using it if you workout at night). I started with my usual routine bench at 215 lbs for 6-8 Reps it felt way too light I didn't have to push as hard at 7 & 8, feeling brave (with a spot of course) to see my limits I jumped to 250 for three clean reps and one assisted. I was sold as a customer! I could barely do one before! What ever is in the stuff is potent and serious and my squat was the same "Insane". After leaving the gym I had a serious cramp in my hams probably from not drinking enough water but this never happened before so I recommend drinking plenty of good fluids and keeping it clear on the way out the day prior or maybe two days for hydration. Afterwards I had a killer headache that eventually went away, which I expected because it has good insulin boosters in it. I highly recommend this product! Give your body a few days to get used to it.

Good but, has a big side effect!
I take M-Stak about 30-45 minutes prior to my workout and the pulse and pump I get from it is great. After about a week or so I feel I can workout longer, I have a better recovery time but lately after about 1-2 weeks I'm getting chronic bad insomnia. Even taking these at 9:30AM then working out around 10AM or so I still have the inability to sleep at night even after long workouts that would normally make me pass out at night.

Regardless I'm seeing some noticeable gains even with just matching it up with a decent protein shake after a workout.

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

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.

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!
