Product Description
Listen to Alex Rogers, President of Protein Factory, talk about this stack and how to use it.
Maximal strength and high-intensity performance are not limited by motivation or effort — they are limited by cellular energy availability.
The C-P-C Stack was developed to support the ATP–creatine energy pathway, the primary system responsible for short-duration, high-power muscular contractions. This pathway governs performance during heavy resistance training, sprint-type efforts, and repeated maximal or near-maximal sets.
Rather than relying on stimulants or subjective “pump” effects, C-P-C is designed to support fundamental bioenergetic processes that directly influence strength output, training volume, and recovery between efforts.
What Is the C-P-C Stack?
The C-P-C Stack is a synergistic combination of performance ingredients formulated to support:
• ATP regeneration
• Intramuscular creatine availability
• Cellular hydration and volume
• Repeated high-intensity muscle contractions
Each component contributes to maintaining energy turnover at the muscle cell level, allowing athletes to sustain output across multiple sets and training sessions.
This is not a stimulant stack. It does not override fatigue signals.
It supports the physiological systems that delay fatigue.
ATP: The Limiting Factor in Strength Performance
Adenosine triphosphate (ATP) is the immediate energy source for muscle contraction. During high-intensity exercise, ATP stores are depleted within seconds and must be rapidly regenerated to sustain force production.
Once ATP availability becomes limiting:
• Force output declines
• Repetition capacity decreases
• Training quality drops
The rate at which ATP can be regenerated is therefore a primary determinant of performance during resistance training and other short-duration, high-power activities.
Supporting ATP turnover is not optional — it is fundamental.
Creatine and ATP Regeneration
Creatine plays a central role in ATP resynthesis by acting as a phosphate donor, allowing ADP to be rapidly converted back into ATP during intense muscular effort.
Extensive research demonstrates that creatine supplementation:
• Increases intramuscular creatine and phosphocreatine stores
• Enhances the rate of ATP regeneration
• Improves maximal strength and power output
• Increases total training volume over time
By allowing faster ATP resynthesis, creatine enables athletes to perform more high-quality work — the primary driver of strength and hypertrophy adaptations.
Cellular Hydration and Muscle Function
Beyond ATP regeneration, cellular hydration status plays a critical role in muscle performance and recovery.
Increased intracellular fluid volume has been associated with:
• Improved muscle contractile efficiency
• Reduced protein breakdown
• Enhanced anabolic signaling pathways
Supporting cell volume is not about cosmetic “pump” — it is about optimizing the environment in which muscle cells operate under load.
The C-P-C Stack supports intracellular conditions that favor performance and recovery during repeated high-intensity efforts.
Why a Stack Is More Effective Than Creatine Alone
Creatine is effective — but its performance benefits are influenced by the cellular context in which it is used.
Optimizing:
• Energy turnover
• Intracellular hydration
• Repeated contraction efficiency
creates a physiological environment where creatine can exert its full performance-enhancing effects.
The C-P-C Stack is designed to support this environment, rather than relying on a single input to do all the work.
Performance Outcomes Supported by C-P-C
When used consistently alongside structured training, the C-P-C Stack supports:
• Increased maximal strength
• Improved power output
• Greater training volume capacity
• Reduced performance drop-off between sets
• Faster recovery between high-intensity efforts
These outcomes are cumulative — driven by improved session-to-session training quality.
Who the C-P-C Stack Is Designed For
C-P-C is ideal for:
• Strength and power athletes
• Bodybuilders in hypertrophy phases
• Lifters emphasizing progressive overload
• Athletes performing repeated high-intensity efforts
This stack is not designed for casual use or stimulant-driven workouts. It is for athletes who understand that performance adaptations are cellular and repeatable.
The Protein Factory Philosophy
At Protein Factory, formulation begins with human physiology, not marketing trends.
The C-P-C Stack exists because:
• ATP availability limits performance
• Strength gains require repeated high-quality training
• Cellular support determines long-term adaptation
This is supplementation built around mechanism, not sensation.
Usage & Timing (C-P-C Stack)
The C-P-C Stack is built for daily consistency. You’re supporting cellular energy and training output over time — not chasing a one-time “hit.”
One Full Serving =
✅ 1/3 cup GroPro™ Peptides
✅ 1/4 cup Rilose®
✅ 1 serving Creatine (use the serving size listed on your creatine label)
How to Take It
Training Days
Option A (Most Popular): Pre-Workout
• Take 1 full serving 30–60 minutes before training
Option B: Post-Workout
• Take 1 full serving immediately after training
Either approach works — the key is consistent daily intake. Choose the timing that feels best on your stomach and fits your routine.
Non-Training Days
• Take 1 full serving once daily, ideally with a meal (or whenever you’re most consistent)
Mixing Tips (So It Goes Down Easy)
• Mix with water, juice, or your favorite shake
• For best texture, use a shaker bottle and let it sit 30–60 seconds, then shake again
• Stay hydrated daily — performance stacks work best when your hydration is on point 💧
Loading Phase
A creatine loading phase is not required. Daily use will gradually increase intramuscular creatine stores over several weeks. Athletes who choose to load may do so at their discretion, though performance outcomes are comparable over time.
Hydration
Adequate fluid intake is recommended to support intracellular hydration and optimal muscle function.
Note: C-P-C is non-stimulatory and can be used at any time of day without affecting sleep.
C-P-C Stack vs Creatine Alone
Why Cellular Support Matters
| Category | C-P-C Stack | Creatine Alone |
|---|---|---|
| Primary Function | Supports ATP regeneration and cellular performance | Supports ATP regeneration only |
| ATP Availability | Optimized through multiple supportive mechanisms | Improved, but limited to creatine availability |
| Cellular Hydration Support | Yes — supports intracellular volume and efficiency | Limited |
| Performance Consistency | Better maintenance of output across sets | Performance may drop as fatigue accumulates |
| Training Volume Capacity | Higher potential for sustained workload | Moderate |
| Recovery Between Sets | Improved through cellular energy support | Partial |
| Adaptation Over Time | Supports cumulative training quality | Effective but narrower in scope |
| Stimulant Content | None | None |
| Use Case | Strength, hypertrophy, repeated high-intensity training | Basic creatine supplementation |
Summary
Creatine is effective — but performance is not determined by a single variable.
The C-P-C Stack supports:
• ATP regeneration
• Cellular hydration
• Repeated high-intensity contraction efficiency
This creates an internal environment where creatine can function more effectively over time.
The difference is not hype — it is context.
