Athletech DL185 Peptide Muscle Accelerant 84 Caps
Your gut can only absorb so much leucine at once — the rest gets stuck in traffic. DL-185 is a di-peptide that bypasses that limit, using a dedicated absorption channel your regular aminos can't access.
Athletech DL 185 Peptide Muscle Accelerant is a single-ingredient dileucine peptide supplement delivering 2,000 mg per 3-capsule serve across 84 capsules (28 servings). Dileucine is a dipeptide — two leucine amino acids bonded together — absorbed via the PepT1 peptide transporter. In a peer-reviewed human trial it supported 60% greater muscle protein synthesis than the same dose of free leucine [1]. One ingredient, no proprietary blends, plant-based capsule. Available in New Zealand with free delivery over $100.
You're Doing Everything Right.
Your Body Has a Bottleneck.
There's a limit to how much free-form leucine your gut can take up at once. DL 185 is a dipeptide that travels a different lane.
Sound Like You?
You train consistently and eat well, but you feel like you should be getting more back from all that effort.
You already supplement with protein, aminos, or BCAAs and you're wondering whether there's a form that's better studied.
You're tired of supplement hype and want something backed by real published research on real people, not marketing claims.
You want to know what you're taking — one ingredient, no proprietary blends, nothing you can't pronounce or explain.
Why a peptide is absorbed differently
Free aminos share one lane. When you take amino acids — leucine, BCAAs, EAAs, or the aminos in a protein shake — they are taken up as individual amino acids that compete for the same intestinal transporters. At a single sitting there's a ceiling on how much free leucine can move across at once.
DL 185 has its own lane. It is a dipeptide — two leucine molecules bonded together — and the gut has a separate transporter for small peptides called PepT1. The peptide is carried across on that dedicated channel rather than competing in the free-amino queue.
It supports muscle protein synthesis. Because the peptide bond survives digestion, dileucine reaches the bloodstream intact. In a peer-reviewed human trial, 2,000 mg of dileucine supported 60% greater muscle protein synthesis than the same dose of free leucine [1]. It works alongside your current stack, not in place of it.
Free Leucine vs DL 185 Dileucine
The difference is the bond. Free leucine is taken up as a single amino acid that competes for transport. DL 185 is a dipeptide carried on its own peptide channel.
- Taken up as single amino acids
- Compete for the same intestinal transporters
- Uptake is capped at a single sitting
- Studied as the comparison group, not the standout
- A dipeptide — two leucines bonded together
- Carried on the dedicated PepT1 peptide channel
- Peptide bond survives digestion
- Supported 60% greater muscle protein synthesis vs leucine in a trial [1]
What The Published Trials Measured
How It Works
- The peptide bond is the key
Each serve delivers 2,000 mg of DL 185 — two leucine molecules bonded together as a dipeptide. That bond gives it access to a different absorption pathway than a free amino acid.
- It uses the peptide channel
Rather than competing with every other free amino for transport, dileucine is carried across the gut wall on PepT1 — a transporter built specifically for small peptides.
- It arrives intact
The peptide bond is resistant to breakdown during digestion, so dileucine reaches the bloodstream as an intact peptide rather than being degraded first.
- It supports muscle protein synthesis
In a peer-reviewed human trial, 2,000 mg of dileucine supported 60% greater muscle protein synthesis than the same dose of free leucine [1].
One ingredient. Nothing to hide. DL 185 Dileucine (L-leucyl-L-leucine monohydrate) in a plant-based capsule. No proprietary blends, no filler powders, no artificial colours or flavours. The label is short because it doesn't need to be long.
How To Take
- Take 3 capsules with water about 30 minutes before you train.
- On rest days, take 3 capsules with a meal that contains protein.
- One bottle is 84 capsules — 28 days at the recommended daily dose.
Stack With
Lifters running DL 185 usually pair it with creatine monohydrate for training volume and a whey or plant protein to hit a daily protein target. DL 185 supplies dipeptide-bound leucine; the protein supplies the full amino profile your muscles build from.

Common Questions
What is dileucine (DL 185)?
Dileucine is a dipeptide — two leucine amino acids bonded together (L-leucyl-L-leucine monohydrate). Leucine is the essential amino acid most associated with muscle protein synthesis. DL 185 supplies it in bonded peptide form, which is taken up on the PepT1 peptide transporter rather than the free-amino route.
Is DL 185 a drug or a hormone?
No. DL 185 is a food-derived dietary supplement, not a medicine. It is simply two leucine amino acids joined together — the same building blocks found in any protein. It is not a hormone and not an injectable peptide drug. You take it as a capsule with water, like any amino supplement.
Do I need to stop taking my current aminos or BCAAs?
No. DL 185 isn't a replacement for your full amino profile — it supplies leucine in dipeptide form. Keep taking what you're taking. Many people simply add DL 185 to an existing protein and creatine routine.
Where's the published evidence?
Two peer-reviewed human trials in trained adults. Paulussen et al. (2021), Journal of Applied Physiology: 2g dileucine supported 60% greater muscle protein synthesis than the same dose of leucine. Hagele et al. (2024), PLOS ONE: +39.5 kg leg-press 1RM over 10 weeks vs placebo. Individual results vary.
How long does it take to work?
Dileucine supports muscle protein synthesis from the first dose, but visible training progress builds over weeks of consistent training and adequate protein, not days. Use it daily as directed alongside your normal program. Individual results vary with diet, training and consistency.
Can I take it with creatine, pre-workout and protein?
Yes — all of them. They each do something different: creatine for training volume, pre-workout for stimulants, protein for raw material. DL 185 supplies dipeptide-bound leucine. There's no need to cycle it.
Is it suitable for women?
Yes. Leucine is an essential amino acid that works the same way regardless of sex. DL 185 supplies it in dipeptide form. There is nothing hormonal and nothing gender-specific in the formula.
What's actually in the capsule?
2,000 mg of DL 185 Dileucine (L-leucyl-L-leucine monohydrate) and a plant-based capsule shell (hypromellose). That's the complete ingredient list — no fillers, colours, flavours or proprietary blends. There are no major allergens: it contains no milk, egg, soy, gluten, peanut, tree nut, fish or shellfish.
