Animal Stak is a cutting-edge anabolic hormone stack that contains compounds designed to increase testosterone levels, which are necessary for muscle growth and strength 1.

Animal Stak is a natural testosterone booster supplement with ingredients designed to aid in the production and maintenance of testosterone and growth hormones which will enhance exercise performance 1.

The formula also includes hormone amplifiers and ingredients to improve internal anabolic environment and increase testosterone and GH (growth hormone) levels. Animal Stak is often used by bodybuilders and powerlifters who want to optimize muscle growth and overall strength.

Animal Stak Benefits

Animal Stak is a supplement made up of 27 unique herbal ingredients that work together to boost testosterone and HGH (human growth hormone) production naturally. Increases in testosterone and HGH levels will induce an anabolic environment in the body while decreasing cortisol and estrogen (female hormone) production 1. The following active compounds are ingredients in Animal Staks formula, which have been studied and proven to produce results.

Stinging Nettle Root

While the Ancient Greeks used this root as a natural laxative, it is also commonly used to treat urinary problems. According to research, it has antibacterial properties and can be used to treat aches and pains. There is also some evidence that this ingredient can help with prostate enlargement 2.

Longjack Extract Complex

Longjack, or Eurycoma longifolia, is a Southeast Asian evergreen shrub tree and used in Malaysian medicine due to its prospective libido benefits 3. Research found that daily supplementation with this root extract improves stress hormone profiles and certain mood state parameters, suggesting that this remedy could be an effective way to protect the body from the negative effects of “modified” stress 4.

Fenugreek Seed

This ingredient is a herb, similar to clover, that grows in the Mediterranean region. According to research published in the Indian Journal of Pharmacology, you use fenugreek seed for a variety of reasons, including stomach upset, constipation, and inflammation 5. Fenugreek positively impacted testosterone levels according to research published in 2020 5.

Tribulus Terrestris Extract

The Mediterranean fruit-producing plant Tribulus Terrestris has been used for years to improve athletic performance, bodybuilding results in a post-cycle therapy or PCT program, and a variety of other health benefits, including heart and circulatory conditions 6. Despite the fact that Tribulus is widely used in natural testosterone support supplements, there is more evidence that it better improves sexual mood and performance than testosterone levels 6.
