About BCAAs
Branched-Chain Amino Acids (Leucine, Isoleucine, Valine) are the three most important amino acids for muscle protein synthesis. Leucine is the primary trigger, while isoleucine and valine support energy production and recovery.

How to read: Values show percentage of optimal levels. 100% represents ideal amino acid content for muscle protein synthesis. Higher values indicate superior amino acid profile.
📊 Key Market Insights
Complete Nutritional Analysis
Comprehensive breakdown of macro and micronutrients per 334g serving
Protein Efficiency
With 15.0% protein by weight, this product delivers 4.0% of its calories from protein, making it less efficient for lean muscle building.
Leucine Threshold
Exceeds the 2.5g leucine threshold with 5.5g, optimally triggering muscle protein synthesis.
Caloric Density
At 1250 calories per 50g of protein, this equals 25.00 calories per gram of protein - moderate for cutting phases.
Complete Product Analysis
- Optimal leucine content (5.5g) for maximum muscle protein synthesis
- Established brand with quality control standards
- Protein concentration (15%) below premium isolate standards
- Higher sodium content (430mg) may be a concern for some
- No third-party testing certification available
- Limited amino acid profile data from manufacturer
Take 1 serving upon waking to break the overnight fast and kickstart muscle protein synthesis. Mix with water for faster absorption or milk for additional calories.
Consume within 30-60 minutes after training to optimize recovery. The 5.5 leucine content helps trigger muscle repair and growth.
Consider mixing with casein or Greek yogurt for sustained amino acid release overnight.
The Science Behind BLEND Protein
Research-Backed Benefits
Scientific studies have consistently shown that whey protein supplementation, particularly blend, can significantly enhance muscle protein synthesis when combined with resistance training. The high biological value and rapid absorption rate make it superior to many other protein sources.
- Muscle Growth:Studies show 20-25g of whey protein maximally stimulates muscle protein synthesis in most adults.
- Recovery:Whey protein reduces muscle damage markers and accelerates recovery between training sessions.
- Body Composition:Regular supplementation supports lean mass gains while promoting fat loss when in a caloric deficit.
Optimal Dosing Strategy
Based on current research, consuming 50g of protein per serving from this product exceeds typical requirementsfor maximizing muscle protein synthesis. The leucine content of 5.5g meets the threshold for optimal mTOR activation.
