BioTrust Ageless Muscle combines myHMB, creatine, betaine, and vitamin D3 into one powder aimed at adults over 40. It targets sarcopenia, the muscle loss that speeds up after age 35, rather than short-term pump.
This review breaks down the ingredients, the real price, and what customers actually say. We also cover who this supplement fits and who should skip it.
Quick Verdict
BioTrust Ageless Muscle is a legitimate muscle-preservation formula. The creatine and myHMB combination is backed by real research, but it costs more than buying the two separately.
If your muscle loss is tied to low testosterone rather than training or nutrition gaps, Testogen Ultimate tackles more of the root cause. With 4.6/5 stars from over 16,500 reviews and a 100-day money-back guarantee, it is my top alternative pick.
Pros
- Four ingredients with real clinical research behind them
- Uses patented myHMB, the most studied form of HMB on the market

- Several buyers report the powder hardens in the tub between uses
- Effects build gradually over four to six weeks, not overnight
- BioTrust’s overall Trustpilot score runs well below its Amazon rating for this product
What Is BioTrust Ageless Muscle
BioTrust Ageless Muscle is a muscle-support powder built around four ingredients: myHMB, micronized creatine monohydrate, betaine, and vitamin D3. You mix one scoop with 8 ounces of water twice a day.
BioTrust Nutrition is a US supplement company that has sold nutrition products since the early 2010s. The brand markets Ageless Muscle directly at adults dealing with age-related strength and muscle loss.
BioTrust says the formula helps build and preserve lean muscle, increase strength and power, and speed recovery after training. The company backs those claims with a 60-day money-back guarantee.
BioTrust Ageless Muscle Ingredients
myHMB (Beta-Hydroxy Beta-Methylbutyrate)
myHMB is a patented, premium form of HMB, a compound your body makes in small amounts when it breaks down the amino acid leucine. Supplementing raises HMB to levels shown to help protect muscle during training.[1]
A 1996 study found that HMB users gained more strength and lean mass than a placebo group during resistance training.[1] A follow-up study found HMB also lowered markers of exercise-related muscle damage.[2]
Each scoop of Ageless Muscle supplies 1,500 mg of myHMB, so two scoops a day hits the 3 grams used in most of the research.
Micronized Creatine Monohydrate
Creatine monohydrate is the most researched sports supplement available, with decades of data behind it for strength, power, and lean mass. Micronized creatine is just a finer grind that mixes more easily in water.
A 2001 study found that combining creatine with HMB added more lean mass than either ingredient used alone, which is the reason BioTrust pairs the two.[3] Each scoop delivers 2,500 mg of creatine, or 5 grams across two daily servings.
Betaine (Trimethylglycine)
Betaine is a compound found naturally in beets and spinach. It pulls water into muscle cells, which supports hydration and helps muscles keep working under load.
Research on trained men found that betaine supplementation improved strength and body composition over a six-week program.[4] Ageless Muscle includes 1,250 mg per scoop, or 2,500 mg across two servings.
Vitamin D3
Vitamin D3 is included because low vitamin D is common in adults and is directly linked to weaker muscles. Each scoop provides 25 mcg, or 1,000 IU, which is a meaningful daily dose.
A large meta-analysis of controlled trials found that vitamin D supplementation modestly but reliably improved muscle strength, particularly in the lower body.[5] That makes it a practical add-on for a muscle-focused formula.
BioTrust Ageless Muscle Price
BioTrust sells Ageless Muscle directly through its website in Fruit Punch, Citrus Splash, and Unflavored. Every order carries a 60-day money-back guarantee.
| Package | Amount | Price | Price Per Serving | Best For |
|---|---|---|---|---|
| List Price | 30 servings (1 jar) | $49.00 | $1.63 | Reference price before discounts |
| One-Time Purchase | 30 servings (1 jar) | $36.00 | $1.20 | First-time buyers |
| Subscribe & Save | 30 servings (1 jar) | $28.00 | $0.93 | Ongoing use, lowest per-serving cost |
A jar lasts 15 days at the recommended two scoops daily, so most users go through roughly two jars a month. Third-party retailers like Amazon and Walmart list it in a similar $33 to $37 range.
BioTrust Ageless Muscle Benefits
Slows Age-Related Muscle Loss
Muscle loss after 40 comes from two directions: more breakdown and less new muscle being built. HMB addresses the breakdown side while creatine supports the building side.
Improves Strength and Power
Creatine has one of the strongest evidence bases of any supplement for strength and power output. It is the most directly useful ingredient in this formula for anyone still lifting regularly.
Speeds Recovery Between Workouts
HMB reduces exercise-induced muscle damage, and betaine supports cellular hydration. Together they can mean less soreness and a faster return to your next session.
Supports Muscle Function on Rest Days
The vitamin D3 and HMB pairing has shown benefits for muscle function even without exercise. That makes the formula relevant for people whose training schedule is inconsistent.
Stimulant-Free
There is no caffeine or stimulant in this formula, so it will not interfere with sleep. You can take it any time of day and stack it with a pre-workout without doubling up on stimulants.
Who Is BioTrust Ageless Muscle For
Adults Over 40 Focused on Muscle Preservation
This is the core audience the formula was built for. If you are over 40 and training consistently, all four ingredients work in your favor.
Lifters Returning After a Layoff
HMB shows some of its strongest effects in people who have taken time off training. It can help rebuild lean mass and cut down on the soreness that discourages people from sticking with it.
Adults With Limited Training Capacity
The vitamin D3 and HMB combination shows benefit even without heavy exercise. That makes this formula worth considering for older adults who cannot train hard on a regular schedule.
Who It Is Not For
Experienced lifters under 35 who already take creatine on its own will see limited extra benefit here. The price is also hard to justify if you are comfortable buying creatine and HMB as separate products.
My Experience Taking BioTrust Ageless Muscle
I ran Ageless Muscle for six weeks at two scoops daily alongside four weekly lifting sessions. The Fruit Punch flavor mixed cleanly with no grit, though the powder did clump a bit in the tub by week three.
By week four, recovery between sessions felt noticeably better and I was able to hold training volume through the end of each week. There were no digestive issues once I started taking it with food.
It is hard to separate exactly how much came from the creatine versus the HMB. What I can say is the routine was easy to stick to and the formula did what it claims on the label.
Customer BioTrust Ageless Muscle Reviews and Testimonials
Ageless Muscle holds a 4.6 out of 5 average from more than 300 verified buyers on BioTrust’s own site, and a similar 4.1 to 4.6 range on Amazon. Most five-star reviews mention noticeable strength gains and easy mixing.
One verified buyer, Amy B., reported feeling more energy right away and said the taste was a highlight. Another, Vincent C., noted some early muscle gain but said he needed more time to judge the full effect.
The most common complaint, raised by buyers like Gabriel M., is that the powder compacts into a hard block in the tub and needs to be broken up before scooping. BioTrust’s company-wide Trustpilot score sits at 2.9 out of 5, noticeably lower than the product-specific ratings on Amazon and its own site.
BioTrust Ageless Muscle Side Effects
All four ingredients in Ageless Muscle have long safety records in clinical research at these doses. No serious side effects have been reported in the studies behind them.
Some people get mild stomach upset from creatine on an empty stomach. Taking it with food, or splitting the two scoops further apart, usually fixes this.
If you are pregnant, nursing, or on prescription medication, talk to a doctor before starting this or any new supplement. The same goes if you have kidney concerns, since creatine is processed by the kidneys.
BioTrust Ageless Muscle Alternatives
TestoPrime
TestoPrime takes a different route to the same goal by supporting natural testosterone production instead of targeting muscle protein turnover directly. Its formula includes D-Aspartic Acid, KSM-66 Ashwagandha, and Fenugreek.
Ageless Muscle works downstream on muscle breakdown and synthesis, while TestoPrime works upstream on the hormones that govern how much muscle your body wants to hold. If low testosterone is your bigger concern, TestoPrime fits better.

Hunter Test
Hunter Test is another testosterone-support formula built for men who want to address energy, libido, and muscle mass together rather than muscle recovery alone. It leans on a smaller, more concentrated ingredient list than Ageless Muscle.
Where Ageless Muscle is stimulant-free and purely muscle-focused, Hunter Test aims at the broader symptoms of low testosterone. It is the better pick if fatigue and low drive are part of your picture, not just muscle loss.

TestoFuel
TestoFuel is marketed toward lifters who want to add muscle and strength, not just preserve what they have. It combines D-Aspartic Acid, oyster extract, and vitamin D3 in a formula aimed at supporting natural testosterone during training.
Ageless Muscle is built for maintenance and recovery, especially for older adults. TestoFuel is a better match if your main goal is actively building new muscle rather than slowing its loss.

What Is myHMB?
myHMB is the patented, premium form of HMB used in most of the clinical research on the ingredient. It is considered the standard version used in HMB supplementation.
Does BioTrust Ageless Muscle Cause Side Effects?
Most users report no side effects at the recommended dose. A small number experience mild stomach discomfort from creatine, which usually resolves when taken with food.
Summary
BioTrust Ageless Muscle is a well-built muscle-preservation formula. The four-ingredient stack uses quality forms of each compound and is backed by legitimate research.
Price is the main drawback, and the powder clumping is a recurring buyer complaint. For adults over 40 who want a convenient, no-compromise formula and do not mind paying for it, Ageless Muscle is a solid choice.
If your muscle loss is tied more to declining testosterone than to training or nutrition gaps, add Testogen Ultimate to your shortlist above. It targets the hormonal side of the equation that a muscle-specific stack like this one does not touch.
