Efectiv MPS185, 2000mg Dileucine Dipeptide for mTOR Activation and Muscle Support
Efectiv Nutrition MPS185 is a specialist muscle-support capsule built around DL185, a bonded leucine dipeptide that represents the first use of this ingredient in the UK market. It is designed for serious lifters and performance-focused athletes who want leucine-based muscle protein synthesis support in a concentrated capsule format without adding another powder to their daily routine.
Each 4-capsule serving delivers 2000mg of DL185 (L-leucyl-L-leucine monohydrate), which consists of two leucine molecules enzymatically bonded together. This dipeptide structure allows absorption via the PepT1 intestinal peptide transporter, which is a different and potentially more efficient route compared to the standard amino acid transporters used by free-form leucine. Leucine is the primary amino acid responsible for activating the mTOR pathway, the molecular signalling cascade that initiates protein translation and muscle growth. The bottle contains 120 vegetarian capsules for 30 full servings, manufactured in a GMP-accredited facility.
Take 4 capsules around training, either 30 minutes before or immediately after your session, alongside a protein-containing meal or shake to provide the full spectrum of amino acids needed for muscle repair. The goal is to support the mTOR signalling cascade during the period when muscle protein synthesis is most active. MPS185 works best as part of a consistent training and nutrition routine rather than as a one-off supplement, with most users assessing results across a 4 to 8 week training block.
MPS185 is an advanced product best suited to experienced lifters who already have daily protein intake, creatine supplementation and training programming fundamentals covered. It is not a replacement for adequate total protein intake or progressive training. If you are still working on hitting your daily protein target consistently, start with Efectiv Whey Protein and Creatine Monohydrate as the foundation before adding specialist products like this one. For a broader muscle-support formula, Efectiv Build.AI combines PeptiStrong, turkesterone and epicatechin.
