DL185 – Dileucine Peptide

Ultra Labs DL185 (Dileucine Peptide)

Next-Generation Peptide for Performance & Recovery

DL185® is a patented dileucine peptide, formed by bonding two leucine molecules into a unique dipeptide structure. This creates a distinct ingredient that has been explored in modern nutrition and exercise science for its properties compared to standard leucine.

Unlike free-form amino acids, peptide-bound structures like dileucine are being studied for how they are absorbed and utilised within the body, making DL185 an emerging ingredient of interest in advanced performance supplementation.

DL185 has been investigated in peer-reviewed research, including studies comparing its characteristics to leucine in the context of resistance training and muscle protein turnover. While outcomes depend on study design and context, it continues to gain traction as a next-generation amino acid innovation.

This makes DL185 a strong option for those looking to incorporate cutting-edge, research-backed ingredients into their training and recovery stack.
