Quick Take: Thermosterone helps men get lean muscle by promoting anabolism and burning fat. What I like about it is that it’s effective. On the other hand, what I don’t like is that it partly relies on stimulants. Go ahead and read the review and let me help you decide whether this supplement’s pros outweigh its cons.
- A product of Out of the Lab (O2T), Thermosterone is designed to be a “dual-action anabolic + thermogenic physique-enhancing dietary supplement”
- Thermosterone goes the extra mile by not cramming its whopping 20+ ingredients in a shady prop blend
- Has a bunch of stimulants that may trigger a couple of cardiac side effects if you’re sensitive
- Promotes anabolism through boosts in “free” testosterone and a reduction in estrogen and cortisol
- Burns fat mainly through increased thermogenesis but Thermosterone might also help suppress your appetite
- Available to buy online and in retail stores including Amazon and the O2T website. However, it’s not on GNC and it’s actually pretty hard to find.

Thermosterone’s T-Boosters & Other Ingredients
Vitamin C – As an antioxidant that helps protect our cells from harmful free radicals, it may also be beneficial to muscle recovery. However, research suggests that it may be counterproductive to endurance exercise “because it prevents some cellular adaptations”.
Vitamin D – How exactly this vitamin influences testosterone is still yet to be fully understood. Regardless, it’s already been established that higher levels of Vitamin D are correlated to higher levels of testosterone. This Vitamin D3 (cholecalciferol) form also makes it easy to absorb.
Vitamin B6 – Kind of like Vitamin D, research suggests that levels of Vitamin B6 may be directly proportional to levels of testosterone. As P-5-P, this is the preferred form of this vitamin.
Magnesium – Involved in over 300 bodily functions, Magnesium is no doubt essential to male health. Its effects include boosting “free” testosterone and reduction of oxidative stress. Unfortunately, oxide and aspartate are cheap forms of this mineral.
Zinc – Literally required for testosterone synthesis, Zinc is perhaps the most important mineral for healthy test. It also reduces prolactin and helps maintain testosterone after intense exercise.
Fenugreek – Aside from boosting testosterone while lowering estrogen and DHT, this herb is also capable of boosting libido and muscle strength.
Yohimbe – By increasing thermogenesis and lipolysis, Yohimbe acts as a natural fat-burner. However, it may be risky as animal research has shown spikes in both blood pressure and heart rate.
Tongkat Ali – Commonly used to enhance sex drive, Tongkat Ali may also be capable of boosting testosterone while lowering cortisol. Furthermore, it might also be able to lower estrogen.
Tribulus – In healthy young men, research shows that this herb does nothing for both testosterone and athletic performance. There may be hope for older men with already deficient levels of testosterone though. Nonetheless, it’s great for libido.
Caffeine – Most of us take some sort of caffeine drink to give us that quick spike of energy. Moreover, caffeine also has plenty of fat-burning properties including increased thermogenesis and possibly a reduction in calorie intake. The dosage on Thermosterone is quite high though so be careful.
Stinging Nettle – Boosts “free” testosterone by inhibiting SHBG, aromatase, and 5-alpha-reductase.
Velvet Bean – Otherwise known as Mucuna Pruriens, I personally think this herb is one of the more promising natural testosterone boosters. Specifically, this is because its active ingredient, L-DOPA, is capable of boosting LH which in turn could also boost testosterone.
Bitter Orange – In this branded form of Advantra-Z®, this version of bitter orange is standardized for synepherine. This makes it a safer fat-burner and stimulant than its illegal counterpart ephedrine.
Red Pepper – With its active ingredients, it helps burn fat through a reduction in appetite and increased thermogenesis. What’s so cool about this is in Thermosterone, it’s given in tablet form rather than the actual pepper so it doesn’t irritate your guts.
Diindolylmethane and Indole-3-Carbinol – I3C is basically a precursor to DIM. However, in its I3C form, it essentially does nothing. When it’s converted to DIM during digestion though, that’s when it can block the aromatase enzyme and theoretically lower estrogen.
Wild Yam – This plant contains DHEA which is a precursor to testosterone but there’s hardly any evidence of DHEA supplements benefitting T. It might, however, help with growth hormone. Also, since it’s technically a steroid precursor, it may be banned by some sports leagues.
Broccoli – As a cruciferous vegetable, Broccoli contains both DIM and I3C.
beta-Sitosterol – This compound is what gives Stinging Nettle its ability to lower DHT. As such, it’s also been used to treat prostate conditions linked to excessive DHT (i.e., BPH).
Naringin – Responsible for giving grapefruit its bitter flavor, Naringin is converted to Naringenin in humans. According to research, it’s a strong to moderate natural aromatase inhibitor.
AstraGIN® and Bioperine® – These have no testosterone benefits whatsoever but they do boost the bioavailability of the entire Thermosterone formula by enhancing nutrient absorption.
Each serving of Thermosterone consists of 2 tablets and basically, we are to take them 30-60 minutes before exercise with a large glass of water. However, according to Thermosterone, the number of servings (or tablets) you should be taking vary depending on your weight and tolerance.
- For the first few days – Just 1 tablet per day to assess your tolerance
- After you’ve adjusted to 1 tablet, slowly increase to 2, 4, or, 6 tablets per day depending on your body weight:
- >220 lbs – 6 tablets
- 185-219 lbs – 4 tablets
- 150-184 lbs – 2 tablets
- <150 lbs – In the words of Thermosterone, it’s “2 strong 4 u”
Additional instructions from Thermosterone
- “Take THERMOSTERONE™ earlier in the day to help minimize any impact on sleep quality. If desired, THERMOSTERONE™ may also be used before breakfast or lunchtime meals on non-training days. For best results, THERMOSTERONE™ should be combined with a sensible diet, regular intense exercise, and proper rest and recovery. To keep your system responsive to its effects, we suggest cycling off of THERMOSTERONE™ for about 2 weeks after 4-6 weeks of continued use.”
Thermosterone has the ZMA trio of Zinc, Magnesium, and Vitamin B6. It also has solid dosages of Vitamin D and C. Together, these nutrients support healthy levels of testosterone as well as improved performance and recovery. Great combo, Thermosterone!
Moving on, Thermosterone also has a surplus of herbs and most of them are given in top-notch qualities which make them easier to absorb. Furthermore, I like how they build on the V&M’s benefits and provide even more support for anabolism. Specifically, these herbs lower estrogen, DHT, and cortisol while also boosting “free” testosterone. Plus, you get performance and libido benefits, too.
When it comes to burning fat, Thermosterone has Caffeine, Yohimbe, Advantra-Z, and Red Pepper. Collectively, they can incinerate fat in a number of different ways. However, since all of them increase thermogenesis, I expect most of your burned calories to be a direct effect of heightened body temperature.
However, Caffeine, Yohimbe, and Advantra-Z are also stimulants. While this may theoretically give Thermosterone the added PWO edge, it can also come with cardiac side effects.
Does it Work?
Thermosterone is designed to be a hybrid between an anabolic supplement and fat burner. In my opinion, it does a damn good job of being both. It boosts “free” testosterone while also lowering catabolic hormones so your muscles can grow. It also turbo-charges your metabolism mainly by increasing thermogenesis. Although, you might also feel your appetite decline.
However, the dosage on Thermosterone’s stimulants are quite high even with just 2 capsules (and even more so with 4 or 6). For men who are sensitive to stimulants, do take extra caution and take the time to assess your own tolerance so you can gauge the serving size that’s best for you.
- Non-proprietary – Even with over 20+ ingredients, Thermosterone doesn’t hide a single dosage. Kudos!
- Anabolic – It doesn’t just boost testosterone, it also lowers catabolic hormones such as estrogen and cortisol. Plus, you also get performance benefits.
- Thermogenic – Amplifies metabolism with natural fat-burners
- Quality – I like how Thermosterone isn’t being cheap with its ingredients
- Stimulants – This has to be THE WORST THING about Thermosterone
- Risky – Yohimbe alone already carries the risk of spiking your blood pressure and heart rate. Combining it with other stimulants is a bad idea.
- Reviews – …or lack thereof. I’m just not seeing a lot of customer reviews on Thermosterone. On the brighter side, the reviews I did read were mostly positive.
The Bottom Line
Overall, I like how Thermosterone is effective at being a testosterone booster AND a fat-burner. However, I just can’t shake my mind off the potential risks of its stimulants. Had Thermosterone chosen safer alternatives, it would’ve gotten a higher rating from me. Still, if you’re young and healthy, this stack could help you get lean muscle mass and crazy (but jittery) jolts of energy.
