You train. You eat your protein. Here’s what a peptide actually does.
DL185 is dileucine — two leucines bonded into one peptide — at 2,000 mg per serve. One ingredient, printed at dose, with the human research laid out below: what was studied, what was observed, and what it does not establish.
What you’re actually getting
- 2,000 mg of dileucine per serve — the dose used in both published human studies summarised below.
- One ingredient, no proprietary blends — L-leucyl-L-leucine monohydrate, printed at dose, in a plant-based capsule.
- The research, with its limits — each study is shown with what it did not demonstrate and who funded it.
- Fits an existing routine — 3 capsules a day, 28 days per bottle, 10 calories per serve.
Peptide. Here’s the research.
A clear look at the human research on dileucine: what was studied, what was observed and what these studies do not establish.
Athletech DL185 provides 2000mg per serve. The summaries below concern studied dileucine ingredients, not a clinical trial of Athletech’s finished formula. Matching a dose alone does not establish product equivalence.
Studied during 10 weeks of resistance training
In a randomized, double-blind trial, 34 resistance-trained men completed 10 weeks of training while taking 2000mg daily of dileucine, leucine or placebo. The dileucine group improved leg-press strength more than placebo, and leg-press repetitions more than leucine. These were different comparisons; both outcomes did not significantly outperform both alternatives.
Visible limitation: The study did not demonstrate additional lean-mass gains or superior bench-press results. It was a small study; participants stopped creatine, so it did not test additional benefits on top of a creatine stack.
Evidence note: Tested ingredient: RAMPS™ L-leucyl-L-leucine monohydrate. Funded by Ingenious Ingredients; relevant author interests were disclosed. Not an Athletech finished-product trial.
Read the published study — Hagele et al., PLOS ONE, 2024A short-term muscle-protein-synthesis study
In a randomized crossover trial, 10 healthy young men consumed a single 2000mg dose of dileucine or leucine. Over three hours, the measured rate of muscle-protein synthesis was higher after dileucine than after leucine.
Visible limitation: This measured a short-term biological response—not muscle gained, long-term strength, recovery speed or results from every workout. It does not establish that dileucine replaces adequate protein or that this finished product produces the same response.
Evidence note: Ingredient study, funded by Ingenious Ingredients, with disclosed author patent interests. Not an Athletech finished-product trial.

What dileucine is
Two leucines, one bond. Leucine is the essential amino acid most associated with muscle protein synthesis. Dileucine (L-leucyl-L-leucine monohydrate) is two leucine molecules bonded together as a dipeptide — the ingredient form used in the two studies above.
The studied dose. 2,000 mg is the daily dose in the 10-week training study and the single dose in the acute study. That is what a serve of DL185 delivers. Those are ingredient studies; this finished product has not been trialled.
Nothing else in the capsule. 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.
What’s inside (per 3-capsule serve)
| Ingredient | Dose | What it is |
|---|---|---|
| DL185 Dileucine (L-leucyl-L-leucine monohydrate) | 2,000 mg | Two leucine amino acids bonded as a dipeptide; the ingredient studied in the two trials above. |
| Capsule shell | — | Plant-based hypromellose (HPMC). No fillers, colours or flavours. |
How to take it
- 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.
Taking it with other supplements: many people take DL 185 alongside creatine and protein. Note that the 10-week study asked participants to stop creatine, so the combination itself has not been tested. Use as directed.
Is it for you?
Built for
- 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 want to see what has actually been studied before adding anything.
- 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.
Not for
- Anyone under 18
- Pregnant or breastfeeding
- Anyone on medication or under medical care, unless a healthcare professional has advised it
- Anyone expecting a replacement for adequate daily protein
Stack with
Lifters running DL 185 often pair it with creatine monohydrate and a whey or plant protein to hit a daily protein target. That is a stacking suggestion, not a tested additive result — the research section above covers what was actually studied.
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, at 2,000 mg per serve.
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 studies of dileucine ingredients, both funded by the ingredient's developer: a 10-week resistance-training trial (Hagele et al., PLOS ONE, 2024) and a single-dose muscle-protein-synthesis study (Paulussen et al., Journal of Applied Physiology, 2021). Both are summarised, with their limitations and links, in the research section.
How long does it take to work?
The acute study measured a response over three hours; the training study ran for ten weeks. Any 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. DL 185 supplies dipeptide-bound leucine and does not replace protein or creatine. Be aware the 10-week study asked participants to stop creatine, so taking the two together has not itself been tested. 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.
