Hydrolyzed Whey Isolate
34.5g per servingWhat It Is
Hydrolyzed whey isolate is the most advanced form of whey protein available. It starts as whey isolate — already stripped of fat and lactose — and then undergoes enzymatic hydrolysis, which pre-digests the protein into smaller peptides. The result is a protein that absorbs faster, causes less digestive stress, and reaches your muscles at the exact moment they need it most: immediately post-training.
Why We Use This Form
Standard whey concentrate contains fat, lactose, and lower protein density. Whey isolate removes those, but hydrolyzed isolate takes it further — the pre-digested peptides spike amino acid levels in the blood faster than any other protein source. At 34.5g per serving, you're getting a full clinical dose with nothing wasted.
Clinical Research
Hydrolyzed whey protein resulted in significantly faster gastric emptying and elevated plasma leucine concentrations compared to intact whey isolate, leading to a greater anabolic response post-exercise.
Fast-absorbing proteins consumed immediately post-exercise produced a 33% greater increase in net muscle protein balance compared to slower-digesting proteins consumed at the same caloric dose.

Creapure® Creatine
5g per servingWhat It Is
Creapure® is the purest form of creatine monohydrate in the world, manufactured exclusively by AlzChem in Germany. It is the benchmark against which all other creatines are measured. When you see "Creapure®" on a label, you're getting the exact form used in over 1,000 peer-reviewed studies on creatine.
Why Creapure® Beats Generic Creatine
Generic creatine monohydrate is susceptible to contamination with creatinine, dicyandiamide, and dihydrotriazine — impurities that reduce efficacy. Creapure® undergoes HPLC testing to guarantee 99.9%+ purity with zero detected impurities. It's the only creatine tested and verified for use by elite athletes and sports federations globally.
Clinical Research
Subjects supplementing with 5g creatine monohydrate daily gained an average of 4.4 lbs of lean mass over 12 weeks vs. 1.8 lbs in the placebo group — a 144% increase in lean mass accretion.
Creatine supplementation at 5g/day increased peak power output in repeated sprint protocols by 8–14% and significantly reduced fatigue index, allowing athletes to sustain more total work volume.
Generic Creatine
88–95% purity

CarnoSyn® Beta-Alanine
5g per servingWhat It Is
CarnoSyn® is the patented, sustained-release form of beta-alanine — the only beta-alanine clinically proven to increase muscle carnosine levels. Carnosine is your body's primary intramuscular buffer, neutralizing the hydrogen ions (acid) that build up during intense exercise. When carnosine levels are elevated, your muscles can sustain harder efforts for longer before fatigue forces you to stop.
Why CarnoSyn® Is Superior
Standard beta-alanine causes the well-known tingling sensation (paresthesia) and is absorbed rapidly — meaning a large portion never reaches muscle tissue. CarnoSyn®'s patented slow-release formulation extends absorption across 4–6 hours, dramatically increasing uptake into muscle. CarnoSyn® is backed by 55+ published studies and is the only beta-alanine verified by NSF for Sport.
Clinical Research
4 weeks of beta-alanine supplementation at 4–6g/day increased muscle carnosine concentration by 58–80%, with continued increases to 168% above baseline after 10 weeks of sustained use.
Calcium HMB
3g per servingWhat It Is
HMB (Beta-Hydroxy Beta-Methylbutyrate) is a metabolite of the amino acid leucine. When leucine is broken down in the body, a small amount converts to HMB — but not enough to produce meaningful effects from food alone. That's why clinical trials use purified supplemental HMB at 3g/day. Calcium HMB is the most bioavailable, stable, and research-supported form available.
Why It's Superior to Standard Leucine
Calcium HMB delivers the active metabolite directly, bypassing conversion inefficiency. Clinical data shows it reduces muscle protein breakdown and enhances the anabolic signaling pathway — particularly valuable during caloric deficits, intense training phases, or periods of high training volume.
Clinical Research
Subjects supplementing with 3g/day HMB for 3 weeks gained 3× more lean mass and lost significantly more body fat compared to placebo. Muscle damage markers (CPK) were also significantly lower in the HMB group.
Both trained and untrained individuals supplementing HMB showed significantly greater increases in upper body strength and lean mass over 4 weeks of resistance training versus placebo.
Tracer Electrolyte Blend
3.9g per servingWhat It Is
The Tracer Electrolyte Blend delivers a clinically-calibrated combination of sodium, potassium, and magnesium — the three electrolytes most critical to athletic performance and neuromuscular function. At 3.9g per serving, it's designed to actively replace what's lost through sweat during training and prevent performance-degrading dehydration.
Why We Use This Ratio
Most protein powders include a trace amount of electrolytes as a label play — insufficient to make a real difference. Pure Fusion's Tracer Blend is formulated around the actual sweat electrolyte ratio documented in sports science research. Sodium drives fluid retention, potassium maintains intracellular fluid balance and prevents cramping, and magnesium supports ATP production and muscle relaxation.
Clinical Research
Sodium-containing fluids produced superior fluid retention versus plain water after exercise-induced dehydration, driving the osmotic gradient that keeps fluid inside cells.
Electrolyte supplementation (sodium + potassium) during resistance training significantly attenuated performance decrements, with subjects maintaining peak power output and strength longer into their training sessions.
BCAAs (2:1:1 Ratio)
5g per servingWhat It Is
BCAAs — Branched-Chain Amino Acids — are leucine, isoleucine, and valine. They are unique among amino acids in that they're metabolized directly in muscle tissue rather than the liver. The 2:1:1 ratio (leucine:isoleucine:valine) mirrors the natural ratio found in food proteins and is the most clinically validated BCAA ratio in the research literature.
Why the 2:1:1 Ratio Matters
Leucine is the primary driver of muscle protein synthesis (MPS) — it acts as the "on switch" for the mTOR signaling pathway. But leucine alone isn't sufficient; isoleucine and valine support glucose uptake into muscle cells and contribute to recovery. At 5g per serving, Pure Fusion delivers a clinically meaningful BCAA dose — not the 2g you'll find hidden in most protein powders.
Clinical Research
Leucine functions as a metabolic signal that regulates skeletal muscle protein synthesis by initiating the mTOR signaling cascade. Subthreshold leucine intake failed to activate MPS, while doses exceeding the leucine threshold produced robust anabolic responses.
BCAA supplementation reduces muscle soreness, decreases exercise-induced muscle damage markers (CPK, LDH), accelerates recovery between training sessions, and supports net positive muscle protein balance when combined with resistance training.
In a randomized double-blind trial, 5g BCAA supplementation post-exercise significantly reduced delayed onset muscle soreness (DOMS) and preserved muscle function in the 48–72 hour post-exercise recovery window, enabling more consistent training frequency.
