Animal Stak Review

I’m here to cut through the noise and get you the bottom line on Animal Stak. We took our time to create this comprehensive review, focusing closely on the ingredients, side effects, customer-service quality, and scientific studies. We also carefully scrutinized consumer comments from all over the internet. Finally, we narrowed down all the data we gathered to give you the facts you need to make an informed decision.

EDITOR'S TIP: Click here to substitute Animal Stak with a proven testosterone booster such as Pronabolin for better results.

What is Animal Stak?

Firstly, Animal Stak is a program designed to support testosterone levels and enhance strength and performance. The company recommends three weeks on and one week off. The cost for a one-month supply is about $35. There are numerous supplements included in each daily pack. The combined ingredients in Animal Stak are extensive. They include tribulus terretris extract, longjack extract complex, fenugreek seed, stinging nettle root, maca extract, mucuna pruiens seed, polygonum cuspidatum root, diindolymethane, l-carnitine fumarate, milk thistle extract, astragalus root, and ashwagandha extract.

Animal Stak is made by Universal Nutrition. The company was founded in 1977 and is located in New Jersey. They specialize in supplements for bodybuilders and professional athletes, but read on…

Niche Market– “Bodybuilders”

Our first interest is the very narrow market this program is designed for.
The ingredients in the product are centered around increasing testosterone and muscle mass. According to our Research Editor, “This product has many ingredients that would be beneficial to those who are at an optimal weight and focused on bulking up through weight lifting. It has virtually none that would facilitate weight-loss.”

One client noted, “I want more muscle, that’s why I’m trying so hard to lose weight but this didn’t do anything for me.”

Which is something this man also expressed, “I’ve started lifting weights and a lot of the guys that use this are ripped. After a month I haven’t seen a difference.”

Those that are part of the target market had better things to say.

A satisfied bodybuilder exclaimed, “I take this off and one when I really need to kill it.”

While another reported, “This is one of my go-to tricks for maxing out.”

Fat Loss – “Not Really”

Some dieters assume if a product will help them build muscle that it must also facilitate fat loss. But this isn’t necessarily true.

This unhappy reviewer worried, “I didn’t lose any weight at all with this.”

And a commenter mentioned, “I thought there would be more pronounced results. I barely lost anything.”

Some people had a more positive experience.

This satisfied customer said, “It kicked up my workouts and I actually lost a few pounds and look better than ever.”

Which was echoed by another who offered, “I have been breaking my own records since I started this program.”

According to our research, multivitamins are necessary for some extreme athletes, but they won’t support weight-loss. If Animal Stak doesn’t offer any metabolism boosters or appetite suppressants, that’s not ideal.

The Science – “Promising”

At DietSpotlight, we get excited by companies that are able to prove the efficacy of their products. Animal Stak has a lot of great ingredients for individuals who want to boost their testosterone to achieve more substantial muscle mass. But there’s no direct connection to weight-loss.

The Bottom Line – Does Animal Stak Work?

Should I race out for a bottle of Animal Stak? If you are at your goal weight and are a bodybuilder, then this might be a good choice. If your goal is to lose weight, there are better products available which is why we are hesitant to give it an endorsement as a diet formula.

If you want to boost testosterone levels, improve energy and fight the signs of aging, we suggest a product with proven ingredients and strong customer support.

Among the best products we’ve seen in 2016 is one called Pronabolin. The formula contains a combination of nine active ingredients that have been shown in clinical research to help promote fat loss, support testosterone production and boost energy. We didn’t pinpoint any negative consumer reviews but we did not many positive comments about achieving excellent results.

The makers of Pronabolin are so sure of their product that they have begun offering a multiple-bottle discount and 120-day money-back guarantee, which our readers have been taking advantage of.

How Does Animal Stak Compare?

Previous Animal Stak Review (Updated June 15, 2013):

What You Should Know

Animal Stak is a strong fitness supplement created for men who want to lift longer and stronger in the gym. Lifters who are posting great gains and increased reps in the gym, not the goal of every dieter, give testimonials supporting Animal Stak. Dieters should know that some of the ingredients in Animal Stak are included to boost testosterone or reduce estrogen. This could have a negative effect on female menstrual cycles and body hair growth. Some men report increased anger when taking natural testosterone boosters.

List of Ingredients

Vitamin C, Vitamin B6, Magnesium, Zinc, Chromium. Natural Test Complex: Tribulus Extract Complex, Longjack Extract Complex, Avena Sativa Extract. Growth Hormone Secretagogues: Mucuna Pruriens Extract, Alpha Glycerylphosphorylcholine. Vasodilator Complex: Arginine Alpha-Ketoglutarate, Arginine HCL. Aromatase Inhibitors: Calcium D-Glucarate, Diindolylmethane. DHT Blockers: B-Sitosterol, Saw Palmetto Extract, Quercetin. Cortisol Inhibitor Complex: Acetyl-L-Carnitine, Phosphatidylserine. Liver Detoxifiers: Milk Thistle Extract, Lysophosphatidylcholine.

Product Features

There are many ingredients in the Animal Stak, but that is because each packet contains several different tablets. Animal Stak is formulated for use with Animal Test and Animal M-Stak for bodybuilders who want to gain even more muscle and strength. The first few ingredients are basic vitamins and have little to no value for weight loss or fat burn. The real magic begins with the Natural Test Complex. This complex includes testosterone boosters to create the perfect environment in the body for muscle growth. These ingredients will not increase weight loss. The Growth Hormone portion of Animal Stak includes a mind-altering herb, Mucuna Pruriens Extract. This herb is used as an aphrodisiac and antidepressant in many cultures. There is mention of lucid dreaming and increased libido. Vasodilator may not be a common word in a dieter's vocabulary, but it is one that bodybuilders and weight lifters use often. Vasodilators open veins to increase blood flow, essentially carrying the supplement throughout the body more quickly. Dilation of the veins is also a common mental boost during lifting, as veins appear larger than normal size. The Aromatase Inhibitors block production of estrogen. This creates the perfect environment in the male body for muscle gains and growth, but does not have a positive effect on women, in most cases. Some research studies have shown supplementing Calcium D-Glucarate in the female body reduces the risk of estrogen fed cancers. DHT Blockers are included in many male supplements because boosting testosterone boosts DHT, which leads to male baldness. In an attempt to stop hair loss, DHT blockers are included. Typically, bodybuilders will take prescription DHT blockers, but saw palmetto is considered one of the most effective natural ingredients to block DHT. Cortisol can cause the body to store abdominal fat and thus the Cortisol Inhibitor. Liver detoxifiers help cleanse the body to prevent negative side effects from any of the abovementioned herbal ingredients. Animal Stak sells for $58.95 for 21 packs. According to the official website, one pack of supplements is to be taken 30 minutes before a workout. After three weeks on, dieters should take one week off.

    Hi, i was wondering if i can take stak on half dose ? or once every 2 days? actualy i am afraid try the full dose as i dont know what to expect from it. i have done loads of homework/research and i strongly feel i should test this first. any advice ? Thx. Kevin



    My advice is to try’s full pack first and note the results. If you aren’t jumpy or jittery or overly irritable then imo I don’t see the harm in taking the full dosage.

    One tip though avoid any caffeine before you consume as some ingredients aren’t good with caffeine.

    If you do take caffeine I would suggest at least 4 hours after taking it. But you’ll find that you won’t need an additional pick me up as the B vitamins are more that enough for the energy you’ll need.

    Hope that helps

    You should get the Anabolic Stack from Dr Max Powers instead. You can buy online.

    I take this b4 working out and I am stronger. If you have extra money to throw around i highly recommend the Dr Max Powers HGH spray as well. HGH can help you to grow. Everyone knows growth hormone is where it’s at! This isn’t real growth hormone but it’s a natural version of it and it works pretty good. Don’t expect huge gains but expect better sleep and slight growth. If you have extra money laying around get this. If not then get the Anabolic Stack and use it before working out. Thank you!!

    what is the difference between all the animal stack products


    Marc S

    They have different goals. If you want gains its likely your test production reduces after 30 so animal stak is probably for you.stuff works great and i feel great. On top of the world. 21 day cycle then 30 days rest between.
