Efectiv Nutrition MPS185 Dileucine 120 Caps

Efectiv Nutrition MPS185 is the UK's first DL185 Dileucine supplement, delivering a novel dipeptide form of leucine at clinical dose. Each 4-capsule serving delivers 2000mg DL185 (L-Leucyl-L-Leucine Monohydrate). The 120-capsule bottle provides 30 servings.

DL185 consists of two L-leucine molecules enzymatically bonded together to form a leucine dipeptide. Leucine is the primary activator of the mTOR pathway, the key intracellular signalling cascade for initiating muscle protein synthesis after training. Research has demonstrated that dipeptide forms of leucine are absorbed more rapidly and completely through intestinal peptide transporters (PEPT1/PEPT2) than free-form amino acids, and that the dileucine form may provide a more sustained and robust mTOR activation signal than an equivalent free leucine dose. MPS185 is positioned as a post-workout muscle protein synthesis amplifier rather than a bulk protein source.

What separates MPS185 from a leucine powder or a standard BCAA product is the peptide bond delivery format. Standard free-form leucine relies on amino acid transporters that compete with other amino acids for absorption capacity. The dipeptide form uses a separate and non-competitive transporter system, enabling more complete and rapid delivery regardless of co-ingested amino acid load. For athletes already optimising protein intake who want to amplify the mTOR signal at the peri-workout window, this is a mechanistically distinct supplement.

MPS185 suits advanced athletes with optimised total protein intake who are looking for a marginal but mechanistically justified edge in muscle protein synthesis, competitive bodybuilders pursuing muscle gain in the context of frequent structured resistance training, and strength athletes focused on hypertrophy during progressive overload phases. It is not an appropriate protein source for calorie or protein deficits; it supplements adequate intake, it does not replace it. Contains no major allergens.
