Sheer Thermo By Sheer Strength Labs Review

The market seems to be filling up fast with fat burners and their claims to give “instant” results and “shred” those abs. Sheer Thermo isn’t an exception to this.

It claims to attack belly fat along with more aggression and energy, from a substance called Yohimbine that’s been banned in many countries outside the US.

But, it isn’t all bad, it does have some benefits with useful ingredients that could help towards fat loss goals. So with that being said, let’s dive in and have a look inside.

Benefits of Sheer Thermo

  • Increase Adrenaline
  • alcohol craving
  • More Focus 
  • Feel Good factor

The added ingredient of Yohimbine will certainly add to the focus and drive in the gym, but could this lead to an increase of anxiety, heart rate and other that we’ll get into later in this review.

The caffeine will add to feeling more focused whilst doing day to day tasks. It will also help to increase the metabolism slightly, which in turn, could lead to fat burning effects.

The 5-HTP is a favorite for many who not only want to increase their chances of weight loss but also if they want to feel good doing it. It releases serotonin (feel good hormone).

“With the high amount of caffeine and increased adrenaline, we’re more likely to get through the workout and finish the last rep on every set, but will it provide the best thermogenic effect in the body in the safest way without leaving me feeling burnt out? I’m skeptical.”

This leaves me thinking it will more likely to make me feel as if I’m in a fight or flight situation all day long, great if I’m trying to run from a cheetah or dodge a bullet like Neo from the Matrix, that’s not a feeling I want all day every day, thank you very much.

Side Effects?

The ingredient Hordenine which is a component of Bitter Orange Peel is said to increase adrenaline and increase stimulation. When mixed with caffeine (as found in the supplement) can cause serious side effects, such as increases the risk of high blood pressure, fainting, heart attack and stroke.

Also, “Yohimbine” will increase the body’s adrenaline levels and alertness, but it could also lead to anxiety, increased heart rate, and nervousness.

How Much Does It Cost?

My Verdict

Even though there are some benefits for fat loss with the Green Tea catechins, other ingredients start sounding alarm bells in our minds that this supplement could potentially be dangerous for those who are sensitive to caffeine.

Mixing traces of Bitter Orange Peel with caffeine is one way to increase the risk of heart palpitations and nervousness, but adding Yohimbine to the mix could be harmful to anyone who already deals with anxiety and heart problems.

All in all this supplement isn’t totally bad, it has some useful ingredients that can benefit fat loss.

We’d much prefer to see more natural ingredients that promote thermogenic effects such as cayenne pepper, green coffee bean extract and black pepper extract, all ingredients that are safe and increase the body temperature naturally rather than trying to increase adrenaline and possible cause a burnout.
