Product Information



Clear Muscle™ is a new, revolutionary musclebuilding formula powered by BetaTOR®, a novel, never-before-produced metabolite and free acid derivative of leucine and HMB. This one-of-a-kind compound unlocks the true potential of HMB for unprecedented bioavailability, effectiveness, and results. BetaTOR® works to dramatically amplify protein synthesis through the mTOR pathway while simultaneously fighting catabolism by inhibiting the UPP pathway. This puts the body into the perfect state to build muscle like never before.There is no other supplement like this, and it is exclusively available to MuscleTech® in a clear liquid pill.

This result is extraordinary, yet this is the average muscle gain achieved by well-trained athletes supplementing with Clear Muscle™ during an extreme 12-week training program at the University of Tampa. The placebo group only gained 4.6 lbs. Even better, subjects’ combined 1-rep max strength on the bench press, deadlift, and squat increased dramatically over the placebo group. These results are more impressive than any research conducted on protein, creatine, BCAAs, or any other performance-enhancing supplement.

Everyone’s potential is different, and because of that, your results may vary. Clear Muscle™ is a supplement designed to enhance lean muscle and strength gains based on the effort that you put into your own individual program.

Works as advertised
I have always been a beer league athlete, playing sports 2-3 times per week. Started going to the gym 3-4 times per week this past January 2018 without taking any supplements. Wanting to see results quicker, I tried Clear Muscle and I am currently on week 6 of the program. The gains I have seen in this time period match what I saw in the past 6 months. You still need to eat right and put the work in but this product works and I would definitely recommend.

This is definitely one of the most versatile products out there. When I first used it, I was trying to build lean muscle and gained 4 pounds in a week! Later on, I used it while cutting and was able to retain all of my muscle. Clear muscle is amazing.

Not Much Results
I was a newbie at the time which means that I have plenty of potential to gain muscle. That being said I did not experience any significant increases in strengths vs taking no supplements.

Although, it could be bias given I had hit my plateau and was cutting weight for half the time. Will reevaluate another time.

Impressed, and amazed
I havent been taking this all that long, and have only once taken the full dosage of two pills three times during the day.

At first, I did notice that I just felt good, about an hour into my workout, several times this week. But this morning, I think it must have kicked in. Never ever have I had a workout like the one I had this morning. I never had such endurance and drive, and it seemed to only increase. But theres no feeling of being jacked up or jolted. Im simply amazed. And, I noticed that I was in a particularly good mood. Im interested to see what happens next!

Huge gains in strength!
This is a groundbreaking supplement. The free acid form of HMB allowed me to feel a strong pump and recover quicker by staying in a state of protein synthesis. I followed the Clear Muscle 12 week program as recommended and I noticed solid muscle gains and strength, and cut and defined muscle maturity. For instance, I went from maxing 280 bench to 295, and from 335 squat to 365. The Clear Muscle Workout Program is pretty intense and a long workout since your getting every muscle group in one day for 3 days a week, but it was well worth it. I highly recommend the Clear Muscle product, it's common sense to take this over CA HMB, the science backs it up.

After using Clear Muscle religiously for about 3 weeks, I have noticed better pumps during my workouts. I felt a bit more endurance during my training sessions and have definitely gained more lean muscle using this product. It will definitely be a supplement I keep in my cabinet at all times

A shopper on May 26, 2014
BEST ANSWER: I don't believe it will help you lose weight since it is meant to build muscle. If you are working out properly and following a clean diet it could help you lose fat.
