I stacked this a month or so ago with MHP's Up Your MASS for a bulk. I've heard a lot of good things about Stak, but had never gotten around to trying this out. So I gave one can a go, & was thoroughly satisfied. Saw an increase in both size & strength, while staying fairly lean during my bulk. Value is hard to beat.

Overall Effectiveness: A
In one month (1 can) I saw a lot of good happen with this. Strength shot up, put on some good size, & stayed much leaner than I anticipated.

Strength: A+
Saw awesome strength increases with this, mainly in he upper body. I started repping 225 on both the incline & flat bench, I graduated to the 100s on incline & flat presses, started using 50+ on laterals, & overall increased a lot of upper body strength.
I did improve some numbers for my legs, mainly on curls & extensions. For lying leg curls I can legitamtely rep the whole stack (150+), which is something I couldn't even think about before. With leg extensions I started increasing my reps rather easily, & started using weights well north of 200.
Best aspect of Stak by far for me, gets an A+.

Size: A
Put on good, quality size. I started filling out shirts much better, moving from a comfortable XL to having to 2XLs at time. Biggest improvement was in my legs. I've always had a thick lower body, but now even "relaxed" fit pants don't fit. I had nice pair of comfy jeans, that now look like skinny jeans on me. I kinda hafta wear shorts & sweat pants now, simply cuz I don't fit much else.
Another easy A.

Misc. (Muscle density, vascularity, etc.): B
Didn't notice much in vascularity, but density was good. My muscles felt fuller & harder, which is always nice.
Also, since I was bulking, my main concern was pudging out. I only saw a 2-3% increase in BF, which says a lot since I can pack on unwanted weight easy (genetics). I didn't run Stak throughout the entire bulk, but if I did I'm sure I would've stayed leaner.
Grades out good, B.

Profile: A
I like Stak's profile. Its more than just a simple test booster, its a bonafied stack unto itself.
I'm not gonna list the ingredients, but if you look at the back of the A-Stak tin you'll find it holds a lot of stuff that most look for. An aromatase inhibitor, cortisol control, DHT blocker, and more.
I'm not sure I can say I noticed each one working, but I can definitely say Stak has something Pink Magic doesn't.
Good profile grades out high, A

Value: A+
Its a good value no matter how you look at it. 1 can lasts about one month (21 days), & I only paid around $35 at Vitamin Shoppe. Just over $1.60 per serving, but considering all it has to offer that's a pretty good deal.
Well within my budget, Stak grades out high, A+

Overall I loved Stak. My only regret is that I didn't run it longer. I'm strongly considering running Stak again this time for 2 cans if I can. I was more than pleased with my results, & really believe the sky's the limit with Stak.
Universl's Animal does it again, overall grades out high: A (9)

Well I finished my 21 day cycle yesterday. The can comes with 21 packs and you take one pack per day with 7 pills per pack and Universal recommends you take the pack in between meals, and on training days take it prior to working out. I bought my can for about $26 which is a great value considering that overall I was quite satisfied with my results.

I'm 6'1", 196lbs, and 21 yrs old. Right now this is about my 6th month of dedicated lifting. Before I started my cycle I weighed a steady 193lbs and for the past 4 days i've been right at 196. I weigh the same time everyday with no clothes on or food on my stomach. I started to notice more mass in my shoulders about the 10th day.. or at least more definition. And I also noticed a definite increase on my bench strength and endurance. I went up 10lbs on my max bench and my reps for my normal workout increased from 6 reps on my last set to 10 unassisted on bench.

I seemed to be slighty more irritable as some have mentioned but nothing crazy. My single biggest complaint about this product is the acne it caused on my back and chest. I've always been prone to body acne but never like this.. It was almost like cistic acne. Big deep zits. Which is gross but hey its winter and my beach bod is still in the works so no biggie ;p.

I gave it 8's all across the board. I was very satisfied with my progress I while taking this and $26 is a great value. Also worth noting is that I cycled off Kre-Alkalyn right as i began this cycle. So I was half way expecting a strength loss but its quite the opposite. A solid product no doubt....

So this is my first Universal Product. and I am glad to say that I am satisfied with the results of it. I was always a lil skeptical of just regular natty booster because they all seem full of it, but I must say that this product keeps up to its promise. Before I decied to buy it, I was thinking about getting different types of natty test boosters, and other type of Nutraceuticals, but they seemed to add up in prize(although it would last longer); however, I had no idea how to take and in what quantities for it to be effective for me. Animal Stak has pretty much all possible types of natural test booster you can find, and you definitely feel and see a diference. I had better workouts, with increased focus and I was always able to lift my heavy sets for higher reps and 1 or more set. I did not noticed if it made me aggressive, my libido was also normal. No real difference in it, but my muscles started looking fuller, and more dense. I stayed pumped for a good amount of time after my workout( not a super pump though). One thing I did not like was the fact that you have to swallow so many pills on a empty stomach, however, it didn't make feel sick so it was ok. It is a lot pills though that you have to take, but I think anybody here can man up to that.
One thing I need to add, is that my strength gains were very good, but nothing oustanding, but I definitely noticed that difference when I added Animal Stak to my routine, I was not taking any other supps, besides from my regulare protein whic is always ion my stack. It is a great, product that only complaints I have is that it only lasts you 3 weeks, which seems very short to me. The price of $32 on bb.com is not bad, but I which it had at least for the 4 weeks, there must be a reason why they made it like that. Another thing was that my back was breaking out like a 16 year old, I had pimples all over my back, and some on my face, but nothing bad on the face; It is still annoying though.
Although I am 23, I saw great results with this product so I would definitely recommend this to trained athletes and the experienced folks in here. I know they will like it. Next time I use it, I will stack it with Animal Pak. Hopefully my review helps you guys make a decision.

Ive had 2 of these bottles/cans. and took them with m-stak the last time. i find them very helpful. i can see and feel gains and its amazing. But oh god. it makes me so irritable and angry. i feel like ripping peoples heads off all the time. so i warned my gf and she was okay with it. maybe u should do the same before u take it. But still, great product will buy again!.

_________________Value (7/10)_______________
I paid $35 for one can, not a terrible value

_______________Dosage (5/10)________________
7 pills/capsules approximately 30 minutes before workout. There was no aftertaste, but that many pills is inconvenient.

_______________Side Affects (5/10)___________
bloating in the midsection. some acne, but not a terrible amount. Increased Libido

________________Overall (7/10)_______________
I definitely grew while using this product. I stacked this product with A-HD, and while on cycle, I gained 12 pounds. The only downside was my midsection did bloat a little, but that subsided immediately after finishing the product. I would give this product a shot, especially if you are stuck on a plateau, and need something to boost you through it.

Profile: Great mix of ingredients that cover your hormones from a variety of 'angles'. This will include AI, cortisol inhibitors, DHT blockers, liver detoxifiers, but I guess you probably know all this already.

Effectiveness: I didn't do any blood testing but my hormones felt a lot more balanced then they usually do. Mood was consistently better, increased confidence, energy levels, aggression when working out, etc. I believe I could feel this working had a general sense of well-being whilst taking this product. Have been making good muscle gains though I don't have a log to demonstrate any figures etc. Some aggression towards others at points though I'm not sure if I see this as a negative or a positive as at least you know something's working and you can dominate the weights, albeit after ***ing off your girlfriend.

Value: Decent value though in the UK everything gets hiked up a bit due to import costs or whatever, but not too bad.

Overall: Would take this again, I have cycled with Animal Test and without, and been pleased with the results either way. Increased energy when working out and general alpha male feeling throughout the day. Would be interested in trying again and investigating it's benefits further.

Honestly after one box, it's less effective, at elast on me, than other test booster. I'm quite disappointed because usually Animal products are the best in their category (Pak and Flex are awesome and cut good for progressive cut).

Okay SR time for another one of WarMachine's reviews from the steel crushers log. Today we will be discussing Universal's animal stak. While I am sure everyone may already know, animal stak is an effective complex test booster formulated to support several areas of over anabolic support. It contains ingredients that have been shown to increase and support both testosterone and growth hormone levels and output. It also contains an effective complex of anti-estrogenic ingredients, cortisol blockers, vasolidators, DHT blockers, and liver detoxification ingredients. Many would consider animal stak an ideal choice for a post cycle therapy regimen. I personally agree, but of course it should only be part of the regimen not the only thing.

Taste (N/A): The pills within the pack are virtually tasteless and I didn't experience any bad aftertaste or burps following the dosage.

Ingredient Profile (10):

Servings Per Container: 21

As I mentioned in the intro, the profile is quite complete and contains several anabolic favoring ingredients that aid in numerous areas of anabolic support. Longjax, tribulus, and avena sativa have all been demonstrated to have positive effects on testosterone levels. Mucuna Pruriens for gh support, and arginine/AAKG for vasolidation are also good bonuses. Although,

I will state, however, that I believe that there is some under-dosing in a few areas particularly in the cortisol blocking complex and anti-aromatase complex. For example, phosphatidylserine's cortisol reduction properties have been demonstrated at doses of 400 mg or higher. Similarly, Acetyl-L-Carnitine must also be dosed intermediately for such benefits. A total complex of 300 mg is a clear indication that their dosages are somewhat low in this product. Still, potentially with animal stak, I believe that a cortisol blocking benefit can still be seen with conjunction of the other ingredients.

Usage (9): The amount of pills is overwhelming especially to a first time user. However, after a few packs, I think one can become accustomed to it. In addition, each serving of animal stak is relatively convenient to take. Simply take on pack a day about 15-thirty minutes before your workout. This is essentially the way I used it. I would take this along with my hit of alphamine and sometimes with jack3d micro. Goes down well without any contradictions.

Effectiveness (9): In terms of effectiveness I give animal stak a 9 out of 10. In conjunction with my other supplements, animal stak was a remarkably effective test booster especially when coupled with test powder. My gym aggression was intensified and I also found myself pushing more weight and performing my boxing-style hits with more force. Furthermore, along with the primary effects of ultima and modern bcaa, animal stak I believe helped catalyze the fatigue reduction influence because I found in preliminary dosage prior to my dosage of my ultima/bcaa concoction to have a positive effect in fatigue reduction. In other words, because animal stak would be taken before my intra-dosage of ultima and bcaa, I was able to deduce the fatigue reducing benefits by analyzing my endurance with some of my first training movements.

Another noticeable benefit I noticed was the libido increase. I was experiencing wood in the morning, occasionally throughout the day (awkward at times), and even upon going to bed. What man doesn't like that?

Value (9): For the results I experienced, animal stak in my opinion is fairly priced for the most part. The price range varies at 29-35 dollars. I was able to get it for 28 dollars at my local supplement shop. Since you get a three week cycle in each can, I would say this is a fair deal, especially considering the benefits. You'll need two cans to complete a full 6-week cycle. This could raise the value tag somewhat, but I still think it is a decent price. In short, the value knife doesn't seem to graze this supplement.

Cons (2): The "2" is to signify that I believe there are two cons, not critical, but cons nonetheless. The first con as I mentioned in the ingredients section is the fact that some of the ingredients should be dosed higher for their cited benefits. The second con is that, some users may find it an inconvenience not knowing which of the pills contains which ingredients. This was not so much an issue for me, but I am an over-analyzer.

Overall (9): Overall, animal stak gets a 9 out of 10. I would have given it a solid 10, but I believe that based on my experience, animal stak's full benefits can be achieved primarily through a stack of other supplements including DAA, creatine, and protein. Alone, I believe it may not personify the greatest of results based on its profile in some categories of ingredients. Thankfully though, animal stak was not alone when I used it. An exuberant arsenal of several great supplements ensured stak's maximum benefits. For those considering using stak I strongly recommend stacking it with DAA, creatine, and a pre-workout because I truly believe stak's benefits are best experienced as an add-on supplement, not standalone. When stacked, one can potentially experience an increase in strenght, mass, aggression, endurance, and libido. As a final thought, animal stak is definitely worth a try and makes a superb addition to any supplement regimen including those for both recomposition and bulking.

I have used animal stak with fantastic results. While taking the number of pills inthe littleplastic bag could be time consuming, nonetheless it pays to go through the process. One thing that I have noticed is that it dramtically increases the density and size of the muscle, especially when I workout my biceps and triceps. Also, I have found the right combination to complement the animal stak. I just starting using the protein powder pw-30 time released. But the good thing is that it has cla which prevent from gaining bodyfat on the abs. At first I was concerned about time released but I can use it as I workout and having already taken the animal stak and a preworkout . Now Im trying to search how I can complement the animal stak and the pw30 with a good pre-workout.

In addition I noticed that my libido is greatly increased and I have a higher energy level as well as more strength!! I now can go from 85 lbs on the bench press to 105 lbs thanks to animal stak. I noticed no side effects. However, I do follow the guidelines of cycling very carefully. The body needs time to know that it has the capability to produce its own tetesterone. The increassed energy also makes it easier to do my daily brisk walk for two hours. Ive tried other products but this is the best because it is , to me the most natural. Has natural herbs like Longjack, mac etc. Growth hormone I consider natural since our bodies may need a little help onthe way. Now if you want to aid the muscle process even more and get a goodnight's sleep , try eating a dozen cherries everynight. I tried it and I have built more muscle and sleep like a baby. IN essence, and in summary, animal stak is a great product that builds muscle, is invigorating, and is capable of working together with other products for the desired effect.

I know stak is a popular one out there but in my opinion, how can you possibly make serious gains in 21 days???

If you are on testosterone injections it takes more than 21 days to make serious gains so how could stak claim to do so.

The only reason I am giving this a 7 is because I love the redpill in stak. It makes for a great preworkout product and is very clean.

Value: 6/10
Off of bodybuilding.com 21 packs is 35 bucks. This makes for 1.66 a day. The product has a bunch of "complexes" that are super underdosed. For example the "Vasodialator Complex is 750mg????? it only consists of arginine. You need at least 5 grams of Argnine for any form of Vasodialation. Also the cortisol inhibitor complex is 300mg of carnatine and phosphytlserine, you need at least 500mg of ps to get cortisol blocking effects. Everything is very underdosed and I didn't see any effectiveness.

I do like Universal as a company but in my opinion this is a crap product. 21 days of tribulus and longjack extract (avena sativa) is not going to do anything substantial for your testosterone levels.

Overall 6/10
I got zero results from this product. I loved the red pill but if you really look into how much of every ingredient it really doesn't do much. Tribulus is probably the most effectively dosed product and you can buy 2 months worth for 10 bucks at a nutrition store. Stcik to trib, buy some phosphytylserine if you want to lower cortisol and I wouldn't spend my money on this
