Caffeine Anhydrous

Caffeine is the most intensely studied stimulant in the history of sports nutrition (and mankind for that matter). Its effects and benefits are well-documented, aiding motivation, cognitive performance, athletic performance, and weight loss.*


In regards to weight loss, caffeine helps to:

  • Reduce appetite
  • Stimulate metabolism
  • Boost thermogenesis
  • Increase energy expenditure
  • Throttle fat burning (“fatty acid oxidation”) during exercise

Every serving of Ape Sh*t Heat contains 250mg caffeine.*

Cacao Powder

Cacao (Theobroma c.) is most often used in the production of chocolate; the plant is also rich in numerous bioactive phytochemicals noted to offer positive health benefits, including antioxidant polyphenols, natural energy enhancers, and metabolic boosters.*

Among the various phyto actives present in cacao is theobromine -- a “chemical cousin” of caffeine that supports increased blood flow and mood as well as weight loss.* Other polyphenols in cacao may help combat the proliferation of free radicals and stave off oxidative stress.*

Yohimbe Bark Extract 8%

The bark of the yohimbe tree has been used in Ayurveda and other traditional practices for centuries. Its principal bioactive compound (yohimbine) has been investigated numerous times,  delving into the various metabolic pathways it affects, including ones identifying specific receptors on adipocytes (“fat cells”).*

Specifically, yohimbine counteracts a process that encourages fat storage (meaning that yohimbine aids weight loss by limiting fat gain), which supports reductions in total fat mass and body fat percentage. Additionally, yohimbine has also been known to help reduce appetite, further supporting weight loss efforts, enhance mood, and support blood flow.*


Paradoxine is the industry-preferred grains of paradise extract standardized for 6-paradol shown in human studies to help to stimulate brown adipose tissue thermogenesis, reduce body fat mass, and decrease waist circumference.*

Studies also indicate that daily supplementation with grains of paradise extract may encourage greater reductions in visceral fat.*


Clinically-validated, patent-protected black pepper extract demonstrated to improve the bioavailability of numerous nutraceuticals, supporting greater ingredient efficacy and enhancing the benefits of Ape Sh*t Heat.*

The primary bioactive present in black pepper (piperine) also supports increased levels of dopamine (a neurotransmitter that impacts mood, motivation and reward), offering additional thermogenic energy expenditure as well as increased feelings of mood and well-being.*

It works

So I finished my first bottle of Apeshit, with a lean meal plan, and a training program, light cardio, and giant set weight program, and proper sleep, I lost the 12 pounds in like 3 weeks. I felt it working. I didn’t crash, but had energy, along with praying for the Lords help to meet my goal!! I recommend it.

Get that extra energy

After lunch I start to drag some I get up at 0400 and get off work at 1630 so it's a long day this gives me a helping hand after lunch thanks for a good product

Pretty good stuff

It’s fast acting and it doesn’t get me all amped up. It feels like I’m awake and focused, not spinning around cause I’m hyper and full of energy. I feel that it lasts for about 4-6 hrs so taking it before an afternoon workout is all good.


Went back home to NY for a month and ate like a pig. Back in LA after two weeks the abs are ready for the summer.

Great Product

I have been taking this product for 4 days. I no longer feel hungry and I sweat all day. What I enjoy about it is that I don’t feel gittery while on this product. 10/10 would recommend!
