Premier Aminos-FX by Premier Research Labs delivers a clean, practitioner-grade essential amino acid (EAA) formula designed for precision nutrition, performance support, and metabolic efficiency.*

This unflavored powder provides all nine essential amino acids, the foundational building blocks required for protein synthesis, tissue repair, and lean muscle maintenance.* The leucine-rich EAA profile delivers 2 grams of leucine per serving, supporting activation of the mTORC1 pathway, a central regulator of muscle protein synthesis and recovery.*

Unlike incomplete amino blends or protein powders with unnecessary fillers, Aminos-FX delivers targeted amino acid support without added sweeteners, flavors, or sodium, making it ideal for customized supplementation protocols.*

This advanced formula also features Immunell^®, a patented complex of 5’-ribonucleotides (AMP, GMP, UMP, CMP) that support immune system function, intestinal lining renewal, and overall cellular resilience.*

Designed for athletes, clinicians, and wellness-focused individuals, Aminos-FX mixes seamlessly into smoothies, shakes, or beverages without altering taste. Every serving delivers rapid absorption and efficient amino acid delivery to muscle tissue for post-exercise recovery or daily nutritional support.*
