Better RESULTS THAN ANY RESEARCH CONDUCTED ON PROTEIN, CREATINE, & BCAAS 

Researchers at the University of Tampa conducted a randomized, double-blind, placebo-controlled clinical study where they gave one group of subjects the BetaTOR® compound found in Clear Muscle® Liquid HMB; the second group received a placebo. Both groups went through an intense 12-week training regimen consisting of 3 to 5 days of weightlifting per week. Get the program now. The results were staggering – subjects using the precise Clear Muscle® Liquid HMB formula gained 16.3 lbs. of muscle in 12 weeks. The placebo group gained 4.6 lbs. These results are more profound than any results from research conducted on protein, creatine, BCAAs, or any other performance-enhancing compound.

  • THERE IS NO OTHER SUPPLeMENT LIKE THIS AVAILABLE

Clear Muscle® Liquid HMB features BetaTOR®, exclusively from MuscleTech® in a clear liquid pill. Its free acid form, with a water-like consistency, ensures rapid digestion, fast absorption, superior muscle uptake, and no bloating.

  • Protect lean muscle mass

Losing weight shouldn’t mean losing muscle. Clear Muscle® Liquid HMB is clinically proven to reduce muscle breakdown by 58%, helps protect lean muscle mass, keeping you strong, active, and ready to achieve your goals.

  • FITS ALL LIFESTYLES, DIETS, & TRAINING PROGRAMS

No matter where you are on your fitness journey, Clear Muscle® Liquid HMB is designed to work as hard as you do—because results don’t come from just showing up. Remember, everyone’s potential is different, and your results will reflect the effort and intensity you bring to your training.

  • ACTIVE LIFESTYLE FOR LONGER

After the age of 30, adults lose up to 3-5% of muscle mass per decade, impacting strength and mobility. Clear Muscle® Liquid HMB preserves lean muscle, enhancing movement and supporting a longer, healthier, active lifestyle.

Science behind clear muscle

Massive Gains in Lean Muscle – Clear Muscle® Liquid HMB users gained 16.3 lbs. of muscle in 12 weeks, significantly outperforming the placebo group.

Improved 1-Rep Max Strength – Participants saw a combined strength increase of over 170 lbs. across bench press, deadlift, and squat, far surpassing the placebo group.

How it works

How Clear Muscle® Liquid HMB Works?

Clear Muscle® Liquid HMB has been shown to increase protein synthesis by 70% and reduce muscle breakdown by 58%, putting you in the ultimate state to build more muscle—a breakthrough first in sports nutrition.

It achieves this by activating the anabolic (muscle-building) “p70S6k/mTOR” pathway—an essential process for muscle growth. At the same time, it inhibits the ubiquitin-proteasome-proteolytic pathway (UPPP), a key driver of muscle breakdown. By shutting down UPPP activity, Clear Muscle® Liquid HMB helps prevent catabolism, keeping your muscles primed for growth.

  • 15+ Clinical Studies – Most Studied Musclebuilding Pill in Existence

  • Fast-Acting Liquid Pill – 97% Better Absorption than Regular HMB

  • Build Muscle and Strength Faster

  • Improve Recovery and Reduce Muscle Breakdown

Noticeable results

This review is for Muscletech Clear Muscle HMB free acid. This is based off my experience so far with this product. So far it has been a positive experience and have had noticeably improvements while using the product. This product says that it is supposed to increase protein synthesis, allowing you to recover faster and make more gains. Based off my experience so far I would say it has helped. I have made increases this month on my deadlifts, squats and I gained quarter inch on my biceps. I don’t want to give all credit to this product, you gotta work for results but I for sure think it has helped. I am wanting to continue use for a few more months at least to see what happens. They pills come in the form of soft gels. They are a decent size and have a bit of an odor to them. Taste is not bad. Asks that you take 3 times a day and take one before your workout. I look forward to continued use of this product and would recommend anyone that wants to make gains to try.

Building muscle

This does a pretty good at helping build muscle. No jittery feelings with it like some other work out supplements. I will most likely continue to use this either consistently or periodically. If it's easy to find.

Highly recommend

I’ve really enjoyed this product it have given me noticeable size gain. The capsules do smell like vinegar and taste a little, there is no after taste though. I’ve noticed my arms are tighter and feel so much stronger. You have to take the them regularly and workout.
