About ThermOxyn

ThermOxyn by iForce Nutrition is a thermogenic weight loss supplement that claims to help you lose weight, decrease body fat, control your appetite, boost energy, and enhance your mood. In fact, by helping you to “get shredded and unleash your inner sexy,” ThermOxyn is claimed to be the world’s strongest fat burner.

But just because thermogenesis can help you burn more calories and stimulants can help increase your energy, does this necessarily mean that you’ll lose weight? And when it comes down to it, is ThermOxyn worth the money?

How Does ThermOxyn Claim to Work?

iForce Nutrition ThermOxyn is claimed to be an ultra concentrated thermogenic that uses unique ingredient blends to help you lose weight and burn fat faster than ever, all while increasing energy levels without “crashes,” promoting thermogenesis, burning fat without muscle loss, and increasing your basal metabolic rate (BMR). These 4 ingredient blends include:

  • Adrenaplex – Uses caffeine anhydrous and acacia rigidula extract to provide “limitless” energy without the dreaded crash afterward.
  • Thermoplex – Includes citrus aurantium extract and rauwolfia serpentina extract to boost thermogenesis, which can help you burn more calories and fat.
  • Retainplex – Uses lemon verbena extract and raspberry ketone to preserve muscle even with a calorie deficit. In other words, this blend is claimed to help you lose fat and not muscle.
  • Metaplex – Includes garcinia cambogia extract, green coffee bean extract, and olea europae leaf extract to increase metabolism and burn fat throughout the day.

According to the ThermOxyn website, you should take 1 capsule before breakfast and another before lunch for the first 2 days, in order to assess tolerance. From there, you can take 2 capsules before breakfast and lunch, although due to the amount of stimulants in the supplement, you shouldn’t take it within 4 hours of bedtime. For best results, the company recommends using ThermOxyn consistently for 8-12 weeks.

iForce ThermOxyn Pricing & Refund Policy

If purchased directly through the manufacturer, ThermOxyn is priced as follows:

  • 120 capsules: $49.99
  • 10 capsules: $9.99

There is no refund policy listed on the iForce Nutrition website, so we contacted customer service and found out that there isn’t a set-in-stone refund period, and all returns/refund requests are handled on a case-by-case basis (we’ll talk more about this in the final section). With this said, if you’re dissatisfied with ThermOxyn for any reason, you’ll need to contact customer support at 877-743-6460, and your request will then be sent up for approval.

Can iForce Nutrition’s ThermOxyn Help You Boost Energy & Lose Weight?

Whether you’re just beginning your fitness journey and are looking for something to provide a kickstart, or are a seasoned pro and are looking for an extra edge, is ThermOxyn worth your money? Perhaps, but consider the following:

ThermOxyn’s Ingredients

Most importantly, keep in mind that although some of ThermOxyn’s ingredients may help boost thermogenesis and increase energy, there are no definitive clinical studies showing that this necessarily translates into weight loss. In fact, as we’ve written about many times, some of ThermOxyn’s ingredients such as garcinia cambogia, raspberry ketone, and green coffee bean extract, could be considered “flavor of the day” ingredients (usually after appearing on the Dr. Oz TV show), and have almost no clinical evidence to support their efficacy for weight loss.

Also, if you’re sensitive to stimulants, you’ll definitely want to take just one capsule of ThermOxyn and find out how it affects you before taking more. In addition, ThermOxyn contains Citrus Aurantium, and should not be used if you have high blood pressure or other heart-related problems.

Customer Reviews

Overall, ThermOxyn appears to have a mostly positive online reputation, especially for increasing thermogenesis, boosting energy, and leaning up. However, several reviewers claimed that while their clothes may have fit more loosely after taking the supplement, they did not actually experience any weight loss.

Fuzzy Refund Policy

As we mentioned above, there is no official refund policy for ThermOxyn, or any other iForce Nutrition supplement. On one hand, this could be viewed as a positive since the company appears to be willing to discuss refunds with anyone who’s unhappy with their products. On the other hand, this could potentially leave a big gray area in some instances.

In order to alleviate any problems, our recommendation would be to contact the company as soon as you realize that you’re not satisfied with ThermOxyn.

Bottom line:

ThermOxyn appears to be well-received within the fitness community due to its ability to increase thermogenesis and boost energy. However, not all supplements will work for everyone. And considering the high level of stimulants in ThermOxyn, you’ll definitely want to consult with your physician before taking it.


  • Claims to help you lose weight, decrease body fat, control your appetite, boost energy, and enhance your mood.
