Expert Take
Reviewed by Garett Reid, MSc, CSCS, CISSN
Strength coach & sports nutrition specialist · · About the author
  • Animal Stak is a testosterone-support supplement marketed toward experienced lifters looking to improve muscle growth, strength, and recovery. Its formula emphasizes herbal extracts and compounds intended to support natural hormone production rather than supplying hormones directly. However, supporting healthy testosterone levels and actually increasing testosterone in men with normal levels are two very different claims.
  • The formula includes tribulus terrestris, tongkat ali, maca, and ashwagandha, alongside compounds marketed for estrogen regulation and growth hormone support. While tongkat ali and ashwagandha have some promising research, tribulus has consistently failed to demonstrate meaningful testosterone increases in healthy men. Evidence supporting the broader growth hormone and muscle-building claims is also limited.

Overall, I'd approach Animal Stak cautiously. Understand where the research lies and and consider if you think it's worth a try..

Solid product, good ingredients!

Love this product. Energy is up, focus is on point and I can say that I feel good. Pills are large and there are several of them. Not a problem for me but might be for others. Company has been around forever for a reason!!! If you're young, you might not benefit from any test booster... But if your older or getting older like myself, you'll enjoy this little boost in life.

Product comes in pill form

This comes as (21) individually packed pill sets (8 per set) in the canister. I started this about 7 days ago, and the effect was almost immediate. Enhanced stamina and energy, with no sign of a crash. I plan to cycle off for 1 week once I complete the container. Great experience so far.

Just okay

Just okay, not spectacular. I maintained on it while keeping my workouts as intense as they usually are. I paired it with cuts and was intending to try to lose some body fat while keeping strength. I tracked everything and it didn’t really do much. I’ve been on much better supps which is disappointing because I like most of Animal’s products.

Wonderful supplement!

Animal Stak + Creatine has easily earned a spot in my daily regimen. The pill pack format is super convenient to grab on my way out the door, making it effortless to stay consistent with my training goals without dealing with messy powders or extra measuring. It fits seamlessly into my morning routine right alongside my usual gear check and early schedule. I have not had any ill side effects and have more energy and focus during the day. All around a power house regimen! I highly recommend it!

Animal Stak + Creatine, Mens Natural Test Hormone Supplement | 21 Packs

Animal Stak + Creatine, Mens Natural Test Hormone Supplement | 21 Packs I purchased this stak to go along side my trt. It has lots of great ingredients that support testosterone, block estrogen, and protect the organs. I am impressed with the stack over all but the price is pretty expensive and I did receive some damages packs in container so those expensive packs are unusable. One added bonus is they do include a container of creatine with the stack. Unfortunately i think thats how the pills got damaged. I would consider buying them again but I would probably wait until I could catch them on sale.

Comprehensive performance supplement with creatine included

This is a very loaded formula compared with a lot of basic testosterone-support supplements. It combines the usual herbal ingredients with amino acids, minerals, and a separate creatine component, so it covers more than just one category. I like that the packs are pre-portioned and clearly organized. The formula includes ingredients such as tribulus, longjack, maca, arginine, zinc, magnesium, and creatine monohydrate, giving it a broad performance-focused profile. The ingredient list is extensive, so this is probably better suited to someone specifically looking for an all-in-one product rather than a simple single-ingredient supplement. Overall, this is a substantial formula with a lot packed into each serving, and the addition of creatine makes it more complete than many similar products.

Great product but wish it didn't double up on some of my multi-vitamins

I was really excited to get this mens natural testosterone hormone supplement and wanted this to work for me. Where this advertisement lacks is in telling you what the ingredients are up front. For that reason I have included photos so you can see what you are getting. The good: From a testosterone support perspective, this supplement seems to check a lot of boxes. I am by no means an expert but it seems to have thought of just about everything. The daily packets are convenient and the packaging contains all the information lacking in the advertisement. I wish they had a key showing what each capsule is however. It is a little unsettling just putting a handful of mystery capsules in your mouth. The not so good: I am a person who takes a multi-vitamin every day, so when I noticed that the ingredients include good amounts of vitamin D, B6, magnesium and zinc, I became concerned. I used Chatgbt to access the amounts included in this product, along with my multi-vitamin and as it turns out the amounts of B6, Magnesium and Zinc would be too much for me to take both products. I really wish they had left those out because I will not be able to continue taking these along with my regular multi. If you also take another form of these supplements it might be advisable to look into this. Excessive amounts of B6 can cause nerve damage, magnesium can cause diarrhea and abdominal pain and zinc can block copper absorption. I'm not saying this product has too much of these ingredients, I am simply saying that due to their presence and amounts, I am unable to take this along with my daily multi-vitamin. Secondly, for me the price seems a little steep at $2.33 per day. I noticed they have a frequent purchase plan which can reduce that price and since there are a lot of ingredients included, it may not be unreasonable in the end. The other thing that is bad is that you get a packet of capsules but there is no photographic key as to what each is. If there was, a person could possibly just not take the vitamin capsule...but since there isn't there is no way to know what is what. Conclusion: This seems like a pretty comprehensive testosterone support supplement however due to the presence of B6, magnesium and zinc which are commonly included in most daily multi-vitamins, you may need to access whether taking this would put those amounts over the safe level for you.

Animal Stak + Creatine Has Been a Solid Part of My Training Routine

I've been running this for a few weeks now alongside regular lifting sessions, and the combination of the test support and creatine has been a good pairing rather than having to juggle two separate supplements. Strength has felt more consistent session to session, and the creatine addition seems to help with recovery between heavier lift days so I'm not as wiped out going into the next one. The 21 pack format makes it simple to just grab one and go without measuring anything out, which matters on busy mornings before an early session. No noticeable stomach issues or the jittery feeling some pre-workout adjacent supplements give me, it's more of a steady background support than something with an immediate jolt. Between training and staying active chasing Willow around or getting outdoors, recovery matters as much as the actual lifting, and this has fit into that side of things well. Good option if you want something straightforward without a complicated dosing schedule.

Lots of Ingredients, but Expectations Should Be Realistic

Animal Stak certainly packs a lot into each daily serving. The formula includes vitamin D, magnesium and zinc along with tribulus, tongkat ali, fenugreek, maca, stinging nettle, ashwagandha and several other ingredients aimed at hormone and performance support. I also like the convenience of having everything separated into daily packs. The downside is that the impressive-looking ingredient list doesn’t necessarily translate into a dramatic testosterone or muscle-building effect. Several ingredients are grouped into complexes, so it’s also difficult to know whether every individual ingredient is present at an especially meaningful dose. I wouldn’t expect results anywhere near what the “hormone booster” marketing might imply. It’s an interesting all-in-one supplement from an established brand, but I’d consider it an optional extra rather than something essential for strength or muscle growth. At the current price for only 21 servings, the value is just average.

Individually packaged creatine!

This is a great creatine for workouts and workout enthusiasts. It comes with individually packaged pills to easy carry with you for the day or throw into your back to the gym. High quality ingredients, from a known and reliable brand of creatine that we typically buy in powder format. Very good value, especially since it is prepackaged individual serving sizes.

Nice for the price

This really is two products in one. With this package, you get a big jar with a smaller jar of creatine and 21 packs of these supplements. I got this, having already taken creatine regularly, and wanted to see if it would make a difference. After only a few days, I can say that it doesn't seem to be much different from my regular creatine, but as these things usually take longer to take effect, it's possible that the other supplements are making a difference. I did not notice any noticeable gains in the weightroom nor effects on my energy, though it has been an admittedly stressful month and I have been running pretty hard at work and at home. I will say there have not been any notable losses in strength or energy either, so I would definitely say that the creatine is good quality and works just as well (if not better) than the creatine I was already taking. Overall, it's a good idea to get the vitamins and creatine all together so that I don't have to buy them separately. Still a little to early to note any big (or small) improvements in energy or strength from the additional supplements.

No creatine + proprietary blends

This a very mixed bag product. There is a lot that's good but also a number of things that really count against it. Let's get the obvious out of the way first: There is no creatine in here. I can only guess the references to creatine in the product listing is an error. However, the fact that other reviewers don't mention this is curious and makes me wonder if different versions of the product are being distributed. The good: This has nearly every compound you can find in most over-the-counter testosterone supplements all in one place, plus some like astaxanthin and Japanese knot weed that are less common to find. It also has support for muscle growth and recovery. The bad: They use proprietary blends so you don't know how much of each ingredient you're getting. Some people may frankly find this disqualifying since there is a tremendously range of clinical efficacy among the ingredients and, from my perspective at least, there are some ingredients in here like DIM and ashwagandha that I would really prefer to know the dosage of. Also this is loaded with totally unnecessary food dyes like blue #1, yellow #5, and yellow #6. Why? These are pills, they don't need dyes. I wouldn't get this gain until the creatine or no-creatine issue is sorted out. And even then, the proprietary blend issue would leave me hesitant, but that's something you have to decide for yourself.
