Product description

What does “gram for gram up to 10× greater efficiency than whey protein” mean?

Gram for gram, this patented, clinically studied 3.6g amino acid dos stimulates muscle protein synthesis with up to 10x the efficiency compared to 40g of whey protein.

Why is this claim “up to 10×” rather than an exact number?

Gram for gram comparison is based on published human clinical research papers evaluating essential amino acid data to whey dose-response trials.

What are amino acids and why are they important for muscle?

Amino acids are the building blocks of protein and essential for cellular function. Essential amino acids especially leucine trigger muscle protein synthesis to repair and support muscle.

How is this different from whey protein?

Muscle Code’s patented EAA ratio is almost fully absorbed, making a 3.6g dose more efficient than whey or other protein powders with virtually zero wastage.

Does this replace eating protein or using protein powders?

No. Whole foods and whey protein remain important for overall nutrition. This formula is designed to efficiently activate muscle protein synthesis, especially when consuming large amounts of protein isn’t practical or convenient.
