Product Description

Useful For:

  • Natural Bodybuilders & Powerlifters*
  • Classic "Hardgainers"*
  • Maximizing Muscle Gains Naturally*
  • Anabolic & Anticatabolics*
  • Optimizing Non-Hormonal Anabolism*

Face it, you're a classic "hardgainer". This means you got fewer corners to cut. You gotta bust your ass, gotta work twice as hard and eat twice as much just to gain a hard earned pound of muscle. For you, the all new Animal M-Stak has been created.

Animal M-Stak is the ideal hardgainer's pack. Thanks to its drastically improved "nutrient-partitiong" effects, its ability to encourage anabolism via protein synthesis and nitrogen retention, and enhanced anti-catabolic factors, the new M-Stak can turn "hardgainers" into "hard" gainers.*

Now with new and even more potent Natural Flavone/Sterone Complex (including new Turkesterone), Anti-Catabolic Amino Complex (rich in leucine), Anabolic Adaptogen Complex (with safed musli and rosavins), Insulin Potentiating Complex (including colosolic acid and 4-hydroxyisoleucine among others), Energy Complex (as with Animal Pump, all the stims are in one red capsule for convenience and flexibility) and a new M-Factor Complex (with dihyroxybergmottin), the all-new Animal M-Stak is gonna blow the top off the proven original. And then some...*

What is Anabolic?

Protein synthesis. Nitrogen retention. "Nutrient-partitioning". The all new Animal M-Stak. A natural supplement which helps boost anabolism and perfect for the classic "hardgainer" in all of us.*

From green beginner to diehard vet, we’ve all gone through it. Skidding to a halt, our progress idles on a wretched plateau. Can’t gain another pound, workouts are stale, lifts are static. This is the hardgainer’s syndrome, and from the most slender of ectomorphs to the most muscular endomorph, we’ve all been there. Desperate to ignite new growth, we’ll try almost anything.

For those of us so dedicated to this game, these frequent moments of desperation have come to an end. The new M-Stak is here, more powerful than ever, designed to obliterate plateaus and spark an explosion of raw muscle hypertrophy. Building on the legacy built by the original M-Stak formula, the new M-Stak has taken all of the most potent components of its predecessor and cranked it up to the next level.*

Natural Flavone/Sterone Complex

M-Stak has long been built on a foundation of natural anabolic flavones. These substances mimic the actions of bodybuilding pharmaceuticals, but without the harsh and undesirable side effects. Born from Eastern European athletic studies, these anabolic flavones have long been highly touted as performance enhancers capable of eliciting dramatic gains in lean muscle mass. The new M-Stak formula combines the most potent of these anabolic compounds in more hearty dosages, making the long storied anabolic potential of the product all the greater.*

Primary among these flavones are Beta-Ecdysterone and Methoxyisoflavone. These ingredients have the ability to shuttle nutrients toward lean mass accumulation, a process known as nutrient partitioning. Beyond this, these anabolic flavones promote enhanced protein synthesis and nitrogen retention. These are the mechanisms most crucial in the process of new muscle growth, brought about by M-Stak without any hormonal manipulation. *

Rounding out the Natural Flavone/Sterone Complex are Ajuga Turkestanica and Beta Sitosterol. Ajuga Turkestanica contains the potent phytosteroid extract Turkesterone, known to be extremely powerful in advancing protein synthesis. Beta Sitosterol, while having its own inherent anabolic potential, is a cortisol combating compound with dramatic pro-immunity effects.*

Anti-Catabolic Amino Complex

With M-Stak, you also get a mega potent anti-catabolic amino blend. With advanced forms of leucine and the other BCAAs spearheading the mixture, these aminos work from a cellular level to directly stimulate protein synthesis. Studies show that by adding leucine along with a protein/carb meal, you get even greater whole body net protein balance than just consuming protein and carbs alone. These aminos help to stimulate muscle recovery and protein synthesis via translation regulations, all through non-hormonal means. They do this by manipulating key muscle growth regulators such as mTOR, PKB, p70s6k, 4E-BP1, FOXO and MAFbx. These aminos essentially work as a signal for turning on the muscle building process, allowing increased muscle anabolism following a training session.*

Anabolic Adaptogen Complex

We’ve also included key “anabolic adaptogens” such as safed musli, muira puama, rhodiola rosea and kudzu extract. Together these herbs may help increase physical training capacity, improve endurance, minimize the catabolic stress response, decrease mental fatigue as well as support healthy libido and boost immune system function. These are critical factors for naturally enhancing ones performance levels in the gym.

Insulin Potentiating Complex

You also get potent insulin potentiators which works to maximize insulin production. Potent compounds such as K-R-ALA and CinnulinPF™ help your body to utilize ultra anabolic insulin both effectively and efficiently. This equates to increased uptake of glycogen and increased muscle cell volume which contributes to that full, pumped feeling when you workout.*

Energy Complex

M-Stak also delivers a potent energy blend, packed with powerful, natural stimulants, methylxanthines and evodiamine, which are designed to propel you through even the most grueling of training sessions. The addition of this complex, easily identifiable by its red capsule, makes M-Stak perfect for pre-training, lighting that fire under your ass that we all need from time to time. If you train at night, or don't want to take stimulants for whatever reason, simply leave the red capsule out of your regimen.*

M Factor Complex

Finally, M-Stak’s M-Factor transport complex works to maximize nutrient utilization to ensure all of the powerful components of the formula are processed to maximum efficacy. Using ginger root extract coupled with the ultra potent absorption enhancers bergmottin and bioperine, you can be sure that the myriad growth factors in the M-Stak formula are working to their full capacity and are not going to waste.*

M-Stak floods your system with an abundance of anabolic nutrients, switching your muscle building signals on and turning them to full blast. Combining potent flavones and sterones in hefty doses with the most anabolic of amino blends supported by an array pf cutting edge asaptogens in a single pretraining pack designed for optimum absorption, the new Animal M-Stak takes non-hormonal anabolics to a whole new level. Animal M-Stak, The Ultimate Hardgainer’s Stack, has come to turn "hardgainers" into "hard" gainers.*

Recommended Stacking

When you want to fully maximize muscle, performance, and strength, and you want to fully optimize your body's anabolic drive, stack Animal M-Stak with Animal Pump and Universal Torrent.*

Animal M-Stak Frequently Asked Questions:

Why did the M-Stak formula change?

The original Animal M-Stak was launched six years ago, and at the time, though the formula was cutting-edge, non-hormonal, anabolic supplements utilizing flavones were still in their infancy. Six years later, new compounds have come onto the scene. Six years later, the all new M-Stak incorporates the latest, most cutting-edge technologies and new ingredients which have been proven in the real world.

You removed some ingredients from the old M-Stak--how can it be better?

The new M-Stak formula is better because it contains heartier dosages of the most effective compounds contained in the old formula as well as new proven and cutting edge ingredients designed to deliver a powerful anabolic response through non-hormonal means. Plus, the old M-Stak was something of a generalist. The new M-Stak is a specialist---targeted specifically for the hardgainer. You now have options--use the M-Stak to boost anabolism non-hormonally, Stak to boost and optimize natural hormone production or stack them together for greater gains.*

What's the difference between the new M-Stak and Stak?

We designed both the Stak and M-Stak to be natural anabolics, but each works differently. Stak is a natural hormone booster. It works with your body to help enhance key anabolic hormone levels, including testosterone. Animal M-Stak, on the other hand, works to promote anabolism by increasing protein synthesis, nutrient portioning, nitrogen retention, all the while reducing muscle catabolism. In short, Animal Stak can help with performance and strength whereas Animal M-Stak can help with gaining lean mass and size. You can combine the two to get the best of both worlds.*

I heard you should keep protein intake high when on the M-Stak. Is this true?

Yes. One thing that makes M-Stak unique from the Stak and other supplements is its "nutrient partitioning" effects. Clinical studies show the active ingredients in the M-Stak can divert the calories you eat into lean mass accumulation, not fat deposition. In short, more clean calories you eat will go toward promoting muscle building, not fat around your belly. Keeping protein intake high (up to 2g/lb. of bodyweight) will mean more protein synthesis.*

Why does M-Stak have so much leucine?

Leucine may well be the most critical amino for the strength athlete. It is a key essential amino acid that has been shown to work independently of insulin, for increasing the phosphorylation (activation) of key proteins involved in the regulation of protein synthesis. What does this mean? Well it means that leucine is the major factor for turning on the processes that maximize protein synthesis—one of the keys to optimizing whole body protein balance. And yeah, M-Stak, being that it's a natural anabolic, ensures that all natural anabolic bases are covered.*

Will M-Stak be less effective if I take out the red capsule?

No. The red capsule, which contains stimulants, was added to make the new M-Stak perfect for preworkout dosing. Taking out the red capsule will have no negative effect on the anabolic efficacy of M-Stak, you'll just lose the stimulant kick--a desirable result for the night trainer.

What other Animal supplements would enhance the effects of M-Stak?

As intended, all of the products in the Animal line work together well. For the purposes of lean mass accumulation and strength gain, a Animal Pump, M-Stak, Nitro stack would work wonders. If your goal is to get shredded while maintaining lean muscle, try the new M-Stak with Animal Cuts and Nitro. The possibilities are endless. As always, Universal Nutriton recommends that any stack be built on the foundation provided by the Animal Pak.*

Is it necessary to cycle off of M-Stak?

Universal Nutrition generally recommend one week off for every three week cycle of M-Stak. That said, the new M-Stak formula contains no hormonal manipulators and as such will cause no negative effect such as the suppression of natural hormone production over periods of prolonged use. Remember, however, that the human body adapts easily, and the use of any specialty supplement for too long could reduce that product's efficacy.

How can I use M-Stak along with other preworkout Animal products containing stimulants?

In such cases, simply stagger your doses of M-Stak with Cuts or Pump, by taking your M-Stak 3 hours before your workout and the Pump or Cuts 30 minutes before training. Another option would be to take the M-Stak at the same time as Pump or Cuts but to simply remove the red capsule.

If M-Stak is a completely natural anabolic, will I be able to use it for drug tested competition?

In general, yes. There are no hormone boosters or any illicit substances or compounds in the M-Stak formula. That said, better to be safe than sorry. Be sure to run the M-Stak ingredients by your coach, athletic trainer or sanctioning body before adding it to your regimen.

I honestly don't know how well this stuff works, but if nutrient partitioning is possible, then I trust Animal products to make it work as good as anyone. There are studies with good results behind most of the ingredients in this product (e.g. Na-R-ALA). The Energy Complex (a single pill you can remove if you wish) has a nice effect when taking this pre-workout. In my opinion, M-Stak read more is one of those supplements that should strike the interest of those who are in the stages of fine-tuning their physique rather than someone who is just getting started.
