Athletech DL185 Peptide Muscle Accelerant Caps

are designed to help lifters get more muscle-building signal from their training by improving how efficiently leucine reaches muscle tissue. Each serving provides 2,000mg of DL185 dileucine, helping support muscle protein synthesis, training performance, and recovery signalling following resistance exercise.

With one active ingredient and no fillers or proprietary blends, DL185 is designed for athletes looking to maximise the results from their existing protein, creatine, and amino acid stack.

Key Benefits

- Delivers a stronger muscle-building signal
Each serving provides 2,000mg of DL185 dileucine, a bonded leucine peptide designed to deliver leucine more efficiently to muscle tissue. Published human trials report greater muscle protein synthesis compared with the same dose of regular leucine, helping support muscle growth from training.
- More of the leucine you take actually reaches your muscles
Unlike free-form amino acids that compete for absorption, DL185 uses the PepT1 peptide transporter, allowing it to bypass the usual amino acid bottleneck in the gut. This helps more leucine reach circulation and contribute to muscle protein synthesis after training.
- Supports strength and training performance
Human trials reported improvements in reps to failure compared with leucine.
- Helps maximise the results from your current stack
DL185 works alongside protein, EAAs, BCAAs, and creatine, helping improve how effectively your body utilises leucine from your overall nutrition strategy.
- Transparent formula with nothing unnecessary
Contains one ingredient only: DL185 dileucine. No proprietary blends, fillers, colours, or flavours.
- Simple daily dosing around training
The capsule format makes it easy to take pre-workout or with a protein-containing meal, helping integrate seamlessly into your existing training routine.

Targeted Leucine Delivery

Leucine is widely recognised for its role in triggering muscle protein synthesis. However, free-form amino acids must compete with other nutrients for absorption in the digestive system. DL185 is formulated as a dileucine peptide, allowing it to be absorbed via the PepT1 peptide transport pathway rather than standard amino acid transporters.

This alternative pathway allows the peptide to reach circulation through a different mechanism than traditional amino acid supplements, helping support the muscle-building signal associated with leucine intake.

Directions for Use

Take 3 capsules with water approximately 30 minutes before training.

On rest days, take 3 capsules with a protein-containing meal.

One bottle provides 28 servings (84 capsules) when used at the recommended daily dose.

Suitable For

- Resistance training athletes
- Those focusing on building muscle
- Individuals supplementing with protein, BCAAs, or EAAs
- People looking to optimise leucine utilisation within their nutrition stack

FAQs

What is DL185?
DL185 is a dileucine peptide, made by bonding two leucine molecules together. This peptide structure allows it to use a different absorption pathway in the gut compared with free-form amino acids.

Can I take DL185 with creatine or protein?
Yes. DL185 works alongside supplements such as protein powders, creatine, and pre-workouts and does not replace them.

Where's the proof this actually works?
Two published human trials on trained individuals. Paulussen et al. (2021) in the Journal of Applied Physiology: 159% more muscle protein synthesis vs baseline, 60% more than leucine. Hagele et al. (2024) in PLOS ONE: 220% more reps to failure vs leucine. Independent studies, real people, resistance training.

How long before results may be noticed?
Training performance improvements may be noticed within 2–3 weeks, with consistent daily use recommended for at least a month.
