You are not alone. I see this all the time, especially in people who are doing everything “right”.
The truth is, muscle growth takes more than hitting a protein number. Your body needs to deliver leucine fast, in high enough concentrations, to activate mTOR and trigger muscle protein synthesis (MPS).
Here’s what matters most:
– Enough leucine to cross the MPS threshold
– A rapid rise in muscle leucine levels post-training
– Activation of mTOR, the molecular switch for muscle repair
Most proteins digest too slowly to deliver leucine fast enough. And taking more leucine alone won’t solve the problem due to absorption limits.
Dileucine may offer a better path.
Dileucine is a dipeptide made of two bonded leucine molecules. It uses the PEPT1 transporter, allowing it to bypass slower digestion and reach muscle tissue more efficiently than free-form leucine.
Clinical research shows:
– A 2g dose delivers 86% more leucine to muscle in 30 minutes
– Leads to a 60% higher muscle protein synthesis rate than leucine alone
– Improves strength and endurance during training compared to both leucine and placebo
This makes dileucine especially helpful:
– After workouts when the body is most receptive to growth signals
– For adults over 30, when anabolic resistance can slow recovery
– For G L P-1 users and those restricting calories who want to preserve muscle
Try this:
– Take 2g of dileucine within 30 to 45 minutes post-workout
– Pair it with a quality protein source
– Look for a clean, clinically studied option like DL185 from @nnbnutrition
Are you seeing the results you expect from your protein routine?
