What if creatine's plateau isn't the ceiling? New CreaSol SSAT RCT suggests tyrosol extends creatine's gains by supporting the cellular conditions that let the energy actually get used. 7.8X more training volume in 4 weeks.
The CreaSol® SSAT (stabilized tyrosol) study is officially here. After more than a year of anticipation -- starting with preclinical data, then the preliminary human findings we covered in The Upcoming CreaSol SSAT Training Volume Data -- Moltek Nutrition now has a published, peer-reviewed human trial to back it up.[1]
The paper appeared in Nutraceuticals in May 2026, produced by teams at the Applied Science and Performance Institute (ASPI) in Tampa, Florida and Barton College in NC. Lead investigators Dr. Jacob M. Wilson and Dr. Ryan Lowery are well-regarded names in sports nutrition research, with decades of combined experience and dozens of peer-reviewed publications between them spanning creatine supplementation, protein metabolism, body composition, and exercise performance. When researchers of that caliber are behind a new ingredient's clinical program, it's time to pay attention.
CreaSol SSAT Synergizes with Creatine for Upper-Body Training
The core finding: combining tyrosol with creatine produced upper-body training performance improvements that neither ingredient achieved on its own. The authors concluded the pattern points to a synergistic interaction rather than simple additive effects, making this the first human clinical evidence for tyrosol as a creatine performance enhancer.

A Well-Structured Trial
The study enrolled 50 participants (48 completed) aged 18 to 50 years, split into four groups:
Only the Creatine plus CreaSol group (green) posted a significant 5RM bench press training volume gain from baseline to Day 28.
- Placebo
- Creatine alone (3g/day)
- Tyrosol alone (500mg CreaSol® SSAT/day)
- The combination of both 3g creatine and 500mg CreaSol® SSAT
Block randomization, double-blind allocation, external IRB approval through Advarra, and prospective registration on ClinicalTrials.gov (NCT06883292)[2] all check the boxes that matter for a credible intervention study.[1]
One deliberate design choice stands out: creatine was dosed at 3g/day without a loading phase. Early standard protocols used loading periods (typically 20g/day for five to seven days) to saturate muscle stores quickly, but that's not as common in actual modern use. This trial tested whether the combination could produce meaningful results at a lower, more gut-friendly dose over a four-week ramp -- a more practical scenario for everyday supplement users.[1]
The testing battery was more thorough than most ingredient studies attempt. At baseline and after four weeks, the ASPI team assessed: five-repetition maximum (5RM) bench press, sets to failure at 70% and 50% of estimated 1RM; isometric mid-thigh pull, hand dynamometer grip strength plyometric push-ups on a dual ground-reaction force plate 1-mile timed run and estimated VO₂ max blood lactate before and after bench press Psychomotor Vigilance Test (PVT) pre and post exercise perceived soreness and recovery at 24 and 48 hours post-testing.
The Results:
The Tyrosol + Creatine group was the only group to show statistically significant improvements in both repetitions and total training volume from baseline in 5RM bench press. Bench press repetitions improved by +20.8% (p<0.001) and total training volume improved by +25.5% (p<0.001), with a significant group × time interaction for both measures. [1]
Bench press reps climbed 20.8% in the combination group, while placebo, creatine, and CreaSol alone stayed flat or dipped.
When delta changes were compared across groups, the combination outperformed every other condition on repetitions: versus tyrosol alone (p = 0.007), creatine alone (p = 0.02), and placebo (p = 0.02). On training volume, it significantly exceeded tyrosol alone (p = 0.012) and creatine alone (p = 0.03), with a trend over placebo (p = 0.074). To put numbers to it: the creatine-alone group's training volume delta was +14.92 lbs; the combination group's was +135.83 lbs. Overall, the combination delivered 7.8X higher training volume gains than creatine alone, with a 25.5% increase vs. 2.9% increase.[1]
The Creatine plus CreaSol pairing delivered 7.8X the training volume gain of creatine alone, a 25.5% jump versus 2.9%.
The 50% 1RM bench data added further signal. The combination group still significantly increased weight lifted (+4.87%, p = 0.01) and training volume (+18.83%, p = 0.002) from baseline. The combination's training volume delta was also significantly higher than creatine alone (p = 0.042).[1]
At 50% of 1RM bench, the combination produced an 18.8% training volume gain, 5.5X better than creatine on its own.
How CreaSol Works with Creatine
The mechanism case for this combination rests on two complementary systems converging at the same point: the energy machinery inside contracting muscle, and the biological conditions that determine how efficiently that machinery can run.[1]
Creatine's role is well-established: it raises muscle phosphocreatine (PCr) stores, accelerating ATP regeneration during high-intensity contractions and sustaining the kind of repeated, high-tension efforts where performance degrades without it.
Tyrosol, the olive oil compound now enhancing creatine's effects! MolTek Nutrition's CreaSol SSAT shows 28% better strength and 51% greater endurance when paired with creatine.
CreaSol® SSAT works differently. Tyrosol is a phenolic compound from olive products that partially converts to hydroxytyrosol (a more potent metabolite with stronger mitochondrial and antioxidant activity) in humans.[3] Together, tyrosol and hydroxytyrosol attenuate reactive oxygen species generation, support glutathione-dependent antioxidant defenses, and inhibit NF-κB signaling, which is a key driver of exercise-induced muscle inflammation.[1] Tyrosol also activates endothelial nitric oxide synthase (eNOS), which supports blood flow and oxygen delivery to working muscle.
The synergy hypothesis: creatine keeps the phosphate system charged for high-tension work, while tyrosol supports the cellular conditions like redox balance, mitochondrial efficiency, and vascular oxygen delivery that allow that energy to be used effectively set after set. Neither ingredient covers both sides of that equation on its own, which is why the combination appears to outperform both in isolation, and why the benefits showed up in volume and repetitions rather than in raw load lifted.
Protected by Patents
CreaSol® SSAT is now covered by three patents: US12390425B1[4] and US12564564B2[5] in the United States, plus international coverage under WO2026/086649.[6] These patents cover the use of tyrosol as a creatine performance enhancer -- the specific combination that the clinical trial validated, not merely the standalone compound.
More Preclinical Data Coming: Two Doses, One Bigger Story
The human trial established efficacy at 500mg. But brands formulating unflavored creatine powders, gummies, or cost-conscious SKUs need a lower-dose option that actually performs. MolTek recently completed a preclinical study at East China University of Science and Technology (ECUST) to answer that question directly; a formal publication report is in preparation.
The study used four mouse groups:
- Control
- Creatine alone (5g/day human equivalent)
- High-dose combination (500mg CreaSol + 5g creatine)
- Low-dose combination (150mg CreaSol + 5g creatine).
Grip strength and exhaustive time of repeated interval swimming test were assessed at 4 weeks for all groups, with the low-dose group extended to 6 and 8 weeks to track time-dependent effects.
At 4 weeks, the 500mg combination produced approximately +52.5% better exhaustive swimming time versus creatine alone, a statistically significant advantage. The 150mg combination showed no significant improvement at that same timepoint.
In the preclinical study, the 500mg CreaSol plus creatine combo extended swim time 52.5% beyond creatine alone at 4 weeks, while the 150mg dose hadn't yet pulled ahead.
That changes over time, though. When the 150mg group was followed out to 6 and 8 weeks, the gains kept climbing: approximately +41.6% versus creatine alone at 6 weeks and +69.6% at 8 weeks. The 8-week performance from the low-dose group was highly comparable to the high-dose group produced at 4 weeks.
The 150mg CreaSol plus creatine combo built momentum over time, reaching 41.6% better endurance at 6 weeks and 69.6% at 8 weeks versus creatine alone.
Extending Creatine's Performance Gains
The second finding embedded in this data may be the more strategically significant one. After roughly four weeks of 5g/day creatine, muscle creatine stores appear to approach saturation and performance gains from creatine alone begin to plateau. The combination groups at both doses continued producing time-dependent improvements well past that point. The pattern suggests creatine builds up the energy reservoir while CreaSol SSAT extends how far performance can climb once creatine-alone benefits have leveled off.
Grip strength in the 150mg combo group pulled ahead of creatine alone by 17.0% at the 8 week mark.
For product design, the dose split maps cleanly to format and timeline:
- 500mg CreaSol® SSAT: Faster onset, stronger response in the first four weeks. Suited for flavored creatine products and pre-workout formulas.
- 150mg CreaSol® SSAT: Builds more slowly but reaches comparable or greater performance by weeks 6 to 8. Tastes neutral in 8oz of water, better suited for unflavored creatine powders, gummies, and cost-sensitive applications.
If this data holds true in humans, then it means that brands don't have to choose between efficacy and format flexibility... they're choosing a timeline.
The Bottom Line
With a published human RCT, three granted patents, and a growing preclinical data set that now addresses both dose and duration, CreaSol® SSAT has earned the kind of research foundation that separates real ingredients from marketing noise.
The combination of CreaSol® SSAT and creatine produced clinically meaningful upper-body strength endurance improvements in a well-run 4-week trial at a low creatine dose with no loading phase. A second human clinical study with a longer intervention and a lower CreaSol dose is currently underway. When those results are in, the dose-response picture will be complete in humans.
Until then, the question for any brand running a creatine SKU is whether the formula is doing everything it could be.
