Matt   Age: 24

"... Hi guys, planning to use M-Stak in the beginning of 2017. However, i hit the gym in the early mornings as it is the only time i am able to with work, girlfriend and studies. My question is when to take it? My Morning looks like this:
5am - Wake up & Pre WO
5:35am - Gym
6:45am - Post workout shake
7:30am - Breakfast shake (technically the first meal of the day)
The problem being that if i were to take M-Stak 30 mins before training, id have to take it on an empty stomach with the red pill which could be abbrasive.
A few other threads and forums ive scoured about m-stak dont say much about early morning timing for animal products.
Can anyone advise?"

"... I've taken m stak alone an stacked with animal stack.... Both are good I have seen noticable results when taking them an can say the gains do not go away after, its not a steroid but it does work. best results I get is from 2 cans of mstak an one animal stak. Take mstak alone 21 days wait a week, then take both for 21 more then take about 2 months off just so your body doesn't get used to the herbs. Decent gains should be made with hard work."

"... I'm only 15 but I feel a difference but is it bad for me to take it at this age I've already started I'm half way done with the can "

response by George

Why the heck would you take it at 15??? BIG MISTAKE and DANGEROUS. Don't get caught up in the fake advertising that you will gain crazy size and strength.. it's fake and hyep.

Instead, focuse on a good meal plan and train properly. Your gains will come. Slowly but surely and will stay. Remember, when you use any testosterone boosters whether natural or illegal the gains will ALWAYS dissapear a few weeks after you stop.

Take your time, be smart about it and by the time you're 20 you'll be ahead of the rest and natural, healthy.

Remember, you need to DIET AND EXERCISE while using this product to make the most of it, the fat will not just melt off by itself.

"... I m planning to use M-stak
so I wanna know dat is it gud for size
and is it do a fat loss?"


October 30, 2014
response by Ken

Increase your testosterone levels at 19 is non-sense. Your levels are already peaked so adding this will give you ZERO results.

If you want progress, all you need to do is adjust your DIET, EXERCISE and recovery times.

You need to take the entire pack of pills, otherwise it's not going to work as is intended.

March 4, 2011
response by Paxton

Big muscle mas comes from eating right and training hard with good recovery in between. Adding M Stack will help improve your results for sure, but not by itself. No product does.

"... Aggression is not a problem if you just keep yourself in check it does increase your test which can make you a lil bit more edgey but you should be ok and there are no other nasty side assiciated with m-stak or stak so anyone wanting to run them dont worry anyone 16+ is fine running this so no worries just train hard and eat right or it wont work plan and simple "

September 6, 2011
response by Chuck

No side-effects from m-stak, unless you go over the recommended dosage. It is a very safe and effective muscle builder and I am sure you will see good results from it.

Also, you are on the right track with taking in protein as well as a pre-workout supplement. I will also suggest some BCAA's throughout the day as well as a good multi.

"... whats up Fellas, i am new to this forum and just to enquire abt M-STAK. I am 31yrs male, been training for almost ten yrs during which i grew from 171pds to my current weight of 195pds my bodyfat is in the region of 15%. i have been stuck on this weight for the past 1.5yrs now and looking overcome this plateau my target is 205pds. A friend recommended M-Stak or Superdrol NG, he advocates for these products as the best and safest on the market. which is what brings me to the forum, what is your take on the products and what is the best way to cycle the product. Thanks cheers"


October 15, 2011
response by Noel

You are in good shape, keep it up. To take it to the next level it takes a combination of proper diet, training and rest along with supplements to give you that extra push. M-Stak will certainly take you to those extra 10lbs, just follow directions and you'll be fine.

"... when taking pro-hormones like this one, you should hit your thighs really hard; quads and hammies, because it will help spike your insulin. between that and the M-stak you'll be getting similar effects to HGH without messing up your bodies chemistry. "

The difference is that M-STAK is much more stronger, safer and cheaper. Yes it will help you increase your strength, new muscle and recovery times.

"... First thing I'd like to say about Animal M-Stak is WOW!!! I've been using M-Stak since 1/12/10 & it has already shown up in an extremely noticeable way. M-Stak has allow my numbers to already soar quite high. I've used other prohormones before but M-Stak has proven to be the best of the rest. My muscles are much harder and much more dense. I'll be running 2 consecutive cycles of M-Stak before cycling with Animal Stak. I expect to continue to make great gains both size and strength wise while using M-Stak. I'm curreny running about 7 UN Aminal Paks. Great products!!! I will most definitely run M-Stak again!"

"... I have mixed feelings with this product. I ate big and clean especially while on it and the only noticeable effect was that I became a little more lean. Nothing extreme, but somewhat noticeable. No strength gains at all, all numbers stayed where they were baseline. No weight gain either, actually lost a few pounds while on it. For me, a few pounds is a lot seeing as how I am small framed and a hard gainer. I was pretty disappointed with this product overall, however, would not count it out as a possibilities for others! "

"... You should not be using this at 16. Read the labels and abide by them. Focus on your diet before taking supps before u should. Stick with the basic "foundational" supps bro. Stunting growth hasn't really been proven...merely a well educated theory. If u wanna stick with universal go with the pak, nitro, and have protein. Not saying I'm perfect... just trying to help you out bro."

response by anonymous

im the same size and age and ive been on it for a week. i havent noticed any side effects. i did however notice that i can now rack almost every leg machine in the weightroom where i work out and i have tons of energy. i can lift for 4-5 hours with only a minute or two break in between each set and i never get tired. i only stop because i get bored. i get great workouts in with animal m stak, animal pak, and creatine all stacked together. ill kep you updated when i finish this cycle on my gains. bottom line, you should be fine. no side effects for me so far


September 18, 2009
response by Blake

I posted already but forgot to mention that nobody should be training for 4 to 5 hours holy jeez. You will most likely overtrain and do more harm than good. Don't beat a dead horse(dont keep training an already efficiently worked muscle). If you cant finish your training in an hour give or take ten minutes...then your not training hard enough or using your time effectively.


February 16, 2010
response by Byron

I agree with Blake brotha. An hour or an hour in a half at the gym is already good enough bro. You don't want to overtrain your muscles because your just killing your gains each time and you'll have to start back from the beginning all over again. Remember, were not like arnold ha ha but we all knew what we used back in the good ol days. But always think, QUALITY not quantity. Oh, and Animal M-Stak is the shiz

"... Just wanted to follow through with the full review for this product. I finished a few days ago and I loved it, I am up to 205 pounds body weight and recently benched 225 for 1 rep. I have not squated during the three weeks but my deadlift did go up. I was originally doing 345 for three reps, now i'm doing 330 for ten reps. Loved the product, great strength and mass gains, my muscles look alot fuller and i am much stronger, no side effects for me other than a very slight increase in acne on my shoulders. minimal and it doesn't matter. BUY THIS PRODUCT!"

"... Okay, so i wasn't going to write about this till the end of my first cycle with it, but on day two i already saw results. Started taking it yesterday on my off day and today was my max effort upper body. My original PR on one rep bench was 195, which is my body weight by the way, but today, on day two of my cycle, i blew through that. I hit 215 with a pause on the chest for one rep. I am definatlely a hard gainer and hope this keeps working like this, i will report back at the end of the cycle."

"... Hey Ali,
unfortunately this supplement will not add "mass" in selected parts of your body. It will however enable your body to help maximise the potential mass you could gain. This is a great product ( i mean really great) but should not be used as a sole supplement. It should be used in conjunction with your other supplements (protein, creatine etc.), and it'll give you that extra boost. Like all supps you need to be working HARD!!...this will give you that extra edge ;)..."

"... I am a big fan of animal m-stak. I actually use most of the universal nutrition supplement line, starting back from over 10 years ago. Just great quality and bang for your buck everyime in my opinion. We all know the prohormone age has come and gone, but thanks to m-stak we can still get the prohormone effects without the unwanted dangers and law! I have been making steady gains over the past 7 months with m-stak, upto the point where friends and family will question whether I am taking anabolic steroids. This is a compliment as I am doing it naturally!"

"... M-stak.. another great innovation from Universal Nutrition. I have been with Universal products for years.. seems liek forever. I was happy when they came out with a "prohormone" type product that delivers results but not the nasty and lethal side-effects. In 2 6 weeks cycles of m-stak, I have gained a total of 34 pounds of lean muscle tissue, lost 4 inches off my waist and finally.. I look great and feel great. No lethargy, no zits, not impatency.. none of that. Just great results.."

Universal Nutrition - Animal M-Stak

The Original Non-Hormonal Prohormone-Free Anabolic Supplement Stack for Hard Gainers

Universal Nutrition has been around for decades thanks to the innovative leadership of flagship supplements such as their Animal M-STAK muscle builder! It's extremely powerful so it should be cycled for a three week period followed by a an off week. Then you are welcome to run it again. The best bet is to treat is as a pre-workout and take it before your training sessions, on rest days the first thing in the morning before breakfast is ideal. The main components to the success of this formula is the addition of methoxyisoflavone, plus the benefits of branch chain amino acids such as leucine and other. It also contains an anti-catabolic function that allows you to hold on to your muscle mass. Listen, there is no need to take short cuts with anabolics that give you temporary results with maximum risk, instead follow naturally induced gains you can keep!
