Clean, Customizable Nutrition
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.
Clean, Excipient-Free Formula
No added sweeteners, flavors, artificial colors, or unnecessary excipients.
Rigorous Quality Testing
Verified for identity, purity, potency, and microbiological safety to ensure uncompromised practitioner-grade quality.
