TSI Group and Iovate have been constructing dietary supplements collectively for 10+ years. From myHMB in Clear Muscle to enfinity paraxanthine in EuphoriQ to FZZR effervescent tech within the EFF’N Sequence.
Contemplate the next merchandise: MuscleTech EuphoriQ, MuscleTech Clear Muscle, MuscleTech Muscle Builder, Hydroxycut Hardcore Liquid Warmth, the MuscleTech EFF’N effervescent collection, and MuscleTech Restoration Peptide 144. They span pre-workouts, fats burners, muscle builders, restoration formulation, power, and hydration. They arrive in powders, softgels, liquid capsules, and fizzing sachets. Some are stimulant-heavy, some are stimulant-free.
They carry two completely different model names and serve very completely different shopper targets. However what do all of them have in widespread?
TSI Group.
Each a type of merchandise runs on an ingredient or supply know-how developed and distributed by TSI Group, a nutraceutical science and manufacturing firm that is labored carefully with Iovate Well being Sciences (the corporate behind MuscleTech® and Hydroxycut®) for nicely over a decade. Not as a catalog vendor, however as a real innovation companion sharing analysis, manufacturing experience, supply codecs, and a dedication to placing science earlier than pattern.
That is the story of how that partnership works, what it is produced, and why it issues for complement customers.
Earlier than we get into the merchandise, join TSI Group information alerts on PricePlow. TSI is the article co-sponsor, and any time a brand new product launches with their substances or know-how, you may be among the many first to know:

The place It Began: BetaTOR and the Clear Muscle Origin Story
The partnership started with two substances that Raza Bashir, Iovate’s Chief Innovation Officer, nonetheless calls a few of his favorites. The primary was BetaTOR, TSI’s patented HMB free acid ingredient (now additionally marketed below the myHMB Clear identify), and the car for its debut was MuscleTech Clear Muscle, which launched in early 2014.
What’s HMB, and why is myHMB® the Greatest?
Learn the total story in PricePlow’s predominant HMB Dietary supplements article.
HMB (β-hydroxy β-methylbutyrate) is a metabolite of leucine, the branched-chain amino acid chargeable for triggering mTOR signaling and the anabolic response. It concentrates leucine’s most helpful results (together with its anti-catabolic properties) at a fraction of the dose required from leucine itself. The place leucine must be taken in impractically giant quantities to meaningfully cut back muscle protein breakdown, HMB produces measurable outcomes at 1.5g to 3g day by day.
The HMB deep dive with researcher Shawn Baier on Podcast #093 covers the total science, the place you may additionally study of the pervasive high quality points within the HMB market which were solved by TSI Group and their trusted and examined myHMB platform.
The free acid type utilized in Clear Muscle issues right here: it reaches peak plasma ranges quicker than calcium HMB, which is precisely what you need round intense coaching. MuscleTech’s liquid softgel supply for Clear Muscle wasn’t a packaging determination made for aesthetics. It was matched to the ingredient’s absorption profile.
Launching a novel compound in 2014 carried actual business threat. As Bashir has famous, “If you’re coping with new compounds, there’s at all times dangers concerned. However that is the place it comes all the way down to that shared imaginative and prescient — it is all about science, and when you’ve got the suitable science, that may be a part of the storytelling.”
That philosophy acquired Clear Muscle to market. It is nonetheless within the portfolio and promoting nicely over a decade later.
PEAK ATP: The Second Founding Ingredient
Peak ATP + Creatine make an epic, synergistic duo to spice up ATP for improved mobile power and muscular good points!
Alongside HMB, the early collaboration produced MuscleTech Muscle Builder, constructed round standalone PEAK ATP®. PEAK ATP is TSI’s patented disodium adenosine triphosphate ingredient, which is precise exogenous ATP that, taken orally, raises extracellular ATP ranges within the physique.
The mechanism is distinct from creatine or some other power ingredient: extracellular ATP indicators via purinergic receptors, which boosts blood move, improves muscle excitability, and reduces neuromuscular fatigue. Analysis has additionally proven that PEAK ATP helps cognitive restoration following intense train, a use case that Dr. Ralf Jaeger explored in depth on Podcast #078.
Muscle Builder gave customers an easy, stackable format to expertise PEAK ATP’s efficiency results. It additionally established the ingredient as a sturdy a part of Iovate’s toolkit, one which’s proven actual synergy with creatine and has stayed related throughout a number of product generations.
The Flagship: EuphoriQ and the enfinity Paraxanthine Unique
If Clear Muscle established the partnership and Muscle Builder deepened it, MuscleTech EuphoriQ introduced it to the broader complement world.
Launched in September 2022, EuphoriQ was the primary shopper complement to make use of enfinity® paraxanthine, TSI Group’s branded type of paraxanthine (manufactured by NNB Diet), caffeine’s main metabolite. Iovate held an unique window with enfinity earlier than it turned accessible to different manufacturers. That is not entry you get from a transactional provider relationship. It is entry you earn via years of scientific alignment and belief. Wanting again, it wasn’t shocking. However on the time, it confirmed that this partnership was working at a distinct degree.
MuscleTech EuphoriQ V2 is right here! It nonetheless has 300mg enfinity paraxanthine, however now helps extra citrulline, added betaine nitrate, and a small hit of yohimbe!
Paraxanthine is price understanding clearly, as a result of it is a genuinely completely different class of power ingredient. When the physique metabolizes caffeine, it breaks down into three metabolites: paraxanthine (roughly 84%), theobromine, and theophylline. Analysis has established that almost all of caffeine’s fascinating results (adenosine inhibition, dopamine upregulation, lipolysis) hint primarily again to paraxanthine. The opposite two metabolites have for much longer half-lives (6 to 7 hours versus paraxanthine’s roughly 3 hours) and seem to drive a big share of caffeine’s much less welcome uncomfortable side effects: jitters, issue sleeping, and the lingering over-stimulation that many customers report.
Through the use of paraxanthine straight, you bypass these metabolites completely. Shopper suggestions and blinded beta testing have constantly confirmed the outcome: a cleaner, smoother power expertise that clears the system considerably quicker. For the roughly 80% of people that don’t get the best expertise from caffeine, paraxanthine is a significant improve.
EuphoriQ V2, launched on the 2024 Mr. Olympia, constructed on the unique with a real ingredient improve: L-citrulline raised to 6g, betaine nitrate added as NO3-T®, L-tyrosine boosted to 1.5g, yohimbe extract, Senactiv®, and the MuscleLyte™ electrolyte mix. The 300mg enfinity paraxanthine core stayed put. It was working.
For the total backstory on how enfinity got here to be, our Podcast #072 with Raza Bashir and Shawn Wells is crucial listening.

Paraxanthine Crosses Over: Hydroxycut Hardcore Liquid Warmth
The enfinity story did not keep in MuscleTech’s pre-workout line. Hydroxycut Hardcore Liquid Warmth introduced paraxanthine into Hydroxycut’s fat-burning class, and the method reveals how TSI substances can transfer throughout model identities with out shedding their scientific rationale.
Paraxanthine is the first metabolite of caffeine, offering most of caffeine’s useful results. Now you possibly can take it straight with enfinity!
Liquid Warmth is a two-liquid-capsule product with 200mg enfinity at its heart, supported by MCT oil (200mg), L-tyrosine (100mg), choline bitartrate (100mg), aXivite® microencapsulated phenylcapsaicin (28mg), grains of paradise extract (15mg), and Hydroxycut’s signature C. canephora robusta inexperienced espresso extract (200mg, standardized for 45% chlorogenic acids).
The method logic holds collectively: paraxanthine offers clear power and helps lipolysis. aXivite phenylcapsaicin and grains of paradise add thermogenic activation via completely different receptor pathways. The robusta espresso extract delivers the chlorogenic acids behind Hydroxycut’s clinically researched weight reduction information. The MCT oil and sesame oil base additionally enhance absorption of fat-soluble compounds.
The identical ingredient powering MuscleTech’s status pre-workout matches naturally in a liquid capsule fats burner for a distinct model below the identical roof. That flexibility (each scientific and logistical) comes straight from TSI’s means to produce constantly throughout product codecs and classes.
Past Elements: FZZRâ„¢ and the EFF’N Sequence
In late 2025, the Iovate x TSI partnership entered new territory with the MuscleTech EFF’N Sequence, three merchandise launched completely at GNC, all constructed round TSI’s FZZRâ„¢ effervescent beadlet know-how.
MuscleTech EFF’N Power delivers 225mg caffeine + 200mg Alpha-GPC in fizzy sachets. No powders, no shakers — simply tear, pour, and go. Out there at GNC in Orange Tangerine Fizz and Blue Razz Fizz.
FZZRâ„¢ shifts TSI’s position from ingredient provider to format innovator. The beadlets dissolve in roughly 80 seconds, making a carbonated beverage expertise from a dry sachet. You may combine them in water or take them direct-to-mouth. There is not any scoop, no shaker bottle, no powder residue.
That may learn as a advertising and marketing angle, however the science beneath it says in any other case. That is as a result of compliance drives outcomes. A complement that works however is disagreeable to take finally will get skipped. As Bashir defined in TSI’s case research for this partnership: “The product has to work. Shoppers should really feel the advantages and benefit from the expertise. If you get that mixture, individuals keep in line with the product and belief the model.”
FZZRâ„¢ additionally solves a real technical problem in product growth: non-compatible bioactives might be co-delivered in a single sachet as a result of the beadlet know-how bodily separates them till dissolution. That opens mixture potentialities that normal powder mixing cannot assist.
The EFF’N line places three distinct use circumstances via the identical format:
EFF’N Power
EFF’N Power delivers 225mg caffeine anhydrous, 200mg GeniusPure® Alpha-GPC (alpha-glyceryl phosphoryl choline), 500mg N-acetyl-L-tyrosine, 2g taurine, and 10mg yohimbe extract (standardized for six% yohimbine) in a single fizzing sachet. It is a targeted power method in a format that travels wherever with out mixing gear.
EFF’N Hydrate
MuscleTech EFF’N Hydrate makes use of effervescent beadlets that fizz in water like a carbonated drink. No scoops, no mess, simply pour and watch it dissolve. Electrolytes + B-vitamins + 1000mg vitamin C + Senactiv. Analysis reveals 20% longer time to exhaustion.
EFF’N Hydrate covers electrolyte replenishment with 350mg sodium, 140mg potassium, 50mg calcium, and 30mg magnesium, layered with 1000mg vitamin C, a full B-vitamin complicated at 25% DV every, and 50mg Senactiv® (the Panax notoginseng and Rosa roxburghii mix additionally present in EuphoriQ V2, with printed information exhibiting a 47% improve in citrate synthase exercise and quicker glycogen replenishment post-exercise).
EFF’N Lower
EFF’N Lower is the thermogenic entry within the collection, constructed round TheoLim® at 450mg, which is a branded mix of lime peel and cocoa extracts designed to assist power expenditure and substrate utilization. Whereas the ingredient has wonderful scientific information behind it, the larger story right here is the way it’s positioned with FZZRâ„¢: a stimulant-friendly fats loss base that enhances the method’s 200mg caffeine dose and 250mg N-acetyl-L-tyrosine for focus and drive.
Rounding issues out, Chromax® chromium picolinate (200mcg) helps wholesome glucose metabolism, giving EFF’N Lower a extra full strategy to weight administration past simply stimulants.
All three can be found completely at GNC, see the hyperlinks above for pricing and availability.
HMB’s Second Act: Restoration Peptide 144
HMB began this partnership, and it is nonetheless producing new product functions over a decade later.
MuscleTech Restoration Peptide 144, a part of MuscleTech’s Peptide Sequence, makes use of myHMB® (powdered calcium HMB) at 1.5g alongside PeptiStrongâ„¢ (2.4g hydrolyzed fava bean peptide, the primary AI-discovered bioactive peptide ingredient) and 500 IU vitamin D3.
MuscleTech Peptide Sequence makes use of focused peptide know-how as an alternative of fundamental amino acids for 70-80% higher absorption. Muscle Peptide 185 (dileucine) delivers 159% higher muscle protein synthesis vs baseline. Plus Creatine Peptide 447 & Restoration Peptide 144!
The method makes use of the powdered calcium salt type moderately than the free acid (BetaTOR / myHMB Clear) that is utilized in Clear Muscle described above. TSI provides each kinds, which lets product builders match the suitable model to every utility – myHMB is for powder, myHMB Clear is for liquid softgels.
The vitamin D inclusion is price calling out: analysis has established that HMB’s means to provide power good points is vitamin D-dependent. Topics with inadequate vitamin D ranges present muscle mass will increase from HMB supplementation however not the corresponding power enhancements. Together with 500 IU within the method addresses that bottleneck proactively.
The mix of PeptiStrong’s mTOR activation and myHMB’s anti-catabolic motion creates what MuscleTech calls dual-pathway restoration assist, concurrently constructing and defending muscle tissue.
The truth that HMB remains to be central to a forward-looking MuscleTech product in 2025, now paired with AI-discovered peptides and vitamin D synergy information, speaks to each the sturdiness of the science and the continued analysis funding behind it.
What Makes a Partnership Like This Final?
The Iovate x TSI collaboration spans greater than a decade, two main model households, a number of ingredient classes, and a supply know-how that did not exist when the connection started. That form of longevity does not occur by default. Just a few issues look like structural to it.
Science comes in the beginning else. Each organizations begin from scientific proof moderately than trend-chasing. As Bashir has put it: “It begins with the science and the patron profit, after which the advertising and marketing and product expertise convey all of it collectively.” Clear Muscle labored as a result of the HMB free acid science was strong. EuphoriQ labored as a result of the paraxanthine science was strong. The format and advertising and marketing adopted from that basis.
TSI is a full R&D companion, not a catalog provider. The collaboration spans method experience, manufacturing assist, supply applied sciences, and shopper insights. That is a meaningfully completely different relationship than buy orders for commodity substances. When FZZRâ„¢ turned viable, Iovate did not must discover a new companion. They already had one constructing it. Bashir described this straight in TSI’s case research: “TSI has constantly expanded from formulations, to manufacturing, to supply methods. It is actually a one-stop store that focuses on each the know-how and the patron to ship full options.”
Shopper expertise is handled as a scientific variable. The perception working via each product above is {that a} complement which works however is disagreeable to take does not ship its advantages, as a result of individuals cease taking it. FZZRâ„¢ exists to resolve that. Clear Muscle’s softgel format exists to resolve that. Paraxanthine changing caffeine for gradual metabolizers addresses compliance at a metabolic degree. TSI’s funding in supply know-how is, at root, a scientific funding in real-world outcomes.
Shared belief allows pace to market. When scientific requirements, high quality expectations, and regulatory alignment are already established between companions, shifting from idea to shelf is quicker. That is how Iovate secured an unique window with enfinity. They had been positioned to maneuver shortly and confidently on a genuinely novel ingredient.

Conclusion: What a Decade of Actual Partnership Produces
Each product lined right here was a calculated dedication to science that was adequate to construct a shopper product round. Some, like PEAK ATP and enfinity, had been novel compounds when the connection started. Others, like free acid HMB and FZZRâ„¢, launched genuinely new classes. All of them made it to market as a result of two organizations trusted one another sufficient to maneuver with confidence.
That is what a long-term ingredient partnership produces at its finest: a shared physique of scientific work that retains compounding. The identical HMB science that launched Clear Muscle in 2014 is now informing vitamin D synergy protocols in a 2025 peptide-based restoration method. The paraxanthine that powered EuphoriQ’s category-creating launch has since crossed into fat-burning, exhibiting up in Hydroxycut’s lineup with a distinct supporting forged however the identical core proof.
What’s subsequent? We’re unsure, however we’ll be excited to announce it when it comes.
