Great stuff

Liked the pill form for a nice change, took two before morning workout and had great workouts both times. Like to try more of these glad they were in the sample pack, great product I think.

Worth a Try!!

Typically I hate pre-workouts. They usually have too much caffeine, they don't give me energy they hype me up on caffeine. My buddy told me about thermosterone and insisted I give it a try. So I did. Loved it. There's an effective amount of caffeine, the ingredients work well with one another and I get a nice pump. I did not get fatigued as quick as I use to. I'm able to rep out my sets and finish my workouts strong. I really have enjoyed this product

Great product you guys had me hooked on it. I ordered my first bottle today, the only problem I had was the coupon you sent with my pack doesn't work unless your order is over $80 so no free t-shirt or $10.00 off your order

Want the Best? Use Thermosterone!

I'm an IFBB Professional bodybuilder, so I'm always searching for high quality products that will help me take my physique to the next level. I have definitely found a winner with Thermosterone! Thermosterone not only provides me with the energy and drive as a pre-workout, without that jittery feeling, but it also is a powerful muscle builder and an effective fat burner. Since using Thermosterone, I have added 12lbs to my physique while maintaining a high level of conditioning, even though my diet hasn't been spot on. I recommend Thermosterone to any one who is serious about improving their physique. I give it excellent reviews in all three categories, As a pre-workout, for promoting lean muscle gains, and as an effective fat burner.

You Must Try This Pre-Workout!

In my opinion, Thermosterone is one of the best pre-workouts on the market hands down. I have tried all sorts of main-stream supplements that are packed with sugar and caffine, and make you feel like bugs are crawling all over you. That is not the case with Thermosterone. It gives you a "clean" focus in the gym with more energy than you know what to do with. My favorite part about this supplement is the pump, it is absolutely killer! You will not regret giving this supplement a shot. It lasts a while and is worth the money, with great value.

Good product, give it a try.

This product is one of my favorites for a couple reasons. First thing, it doesn't have a ridiculous amount of caffeine so I'm not shaking or gittering during my workouts. Second, it doesn't make me nauseous when I lift, and I haven't puked yet using this product. It gives me a great pump and a very consistent flow of energy throughout my workout. The only reasons I lower my weight between sets is due to the amount of blood in the muscle group I'm lifting. I would strongly recommend giving this product a try. I have never crashed after a workout, doesn't leave me feeling sick. The ingredients work well together and have showed me good results so far.

Phenomenal Product

This is by far the best pre-workout product I have tried in years. 1. Efficient, even climb in energy with an incredible steady plateau that takes you through your workout and well beyond. Unlike other products there is sky rocket boost followed by that crash 30 min later. 2. Flexible application based on need. Everyone is different and this product allows you to adjust it to your own needs. I train first thing in the morning. I take 2-4 tablets about and hour before training. 2 if my energy level is already decent. 4 if a need a bigger boost in energy. If you train in the evening I would make sure to take this early in the afternoon because your energy levels will stay high for hours. I also travel a lot on business and being able to carry tablets with me vs. pouches of preworkout powder is a huge advantage in a delivery system. 3. ZERO gut issues. One issue I have with a l

Another skeptic that has become a believer

Took two pills before both my Wednesday and Friday workouts... took them when I left work and I felt like I had plenty of energy to complete high volume workouts. Its welcome relief for me since many of pre-workouts that I've take recently have left me feeling queasy. I plan on buying a bottle within the next couple weeks.

Thermosterone is a novel hybrid formulation that combines the powerful energy of a pre-workout, the thermogenic heat of a fat burner, and the anabolic potential of a natural T-booster – all in one convenient serving.


Why combine metabolic and hormone boosting benefits?

It’s a vicious cycle. Being fat causes T levels to drop. And, lower testosterone is linked with increased body fat, BMI, and waist to hip ratios. If you fail to address excess body fat, you’re wasting your hard-earned cash on hormone optimizing supplements. Thermosterone delivers a powerful 1-2 punch to help increase calorie burning AND support elevated testosterone output, naturally.



Thermosterone supports your physique-enhancing efforts in three distinct ways:

1.First, Thermosterone provides clinically-researched thermogenics to ignite your metabolism and help you burn more calories.

2.Thermosterone is also designed to help naturally optimize hormone levels to create an anabolic environment that helps contribute to lean muscle development.

3.Last, but certainly not least, Thermosterone contains powerful ingredients to help amplify training intensity and  mental energy + focus in the gym, enabling you to get the most out of each workout.  


Other key features and benefits:

• Bodyweight Dosing – Most supplements which use a one-size-fits-all approach, but Thermosterone’s usage suggestions are based upon your individual body weight to provide maximum results at the lowest possible dosage.

• Transparent Labeling – With Thermosterone there is no need to guess how much of a particular ingredient is in each serving. Every active ingredient is clearly listed, so that you know exactly what you’re paying for.

• Meaningful Amounts – Thermosterone delivers effects that you’ll feel in minutes, energy that lasts for hours, and, when combined with diet and exercise, impressive long-term changes to your physique.

• Advanced Delivery – Thermosterone utilizes advanced pharmaceutical-type disintegration technology  and contains nutrient enhancers to help increase nutrient availability and uptake.
