Lean mass

Progressive overload, protein and recovery.

Muscle growth takes progressive overload, enough protein and the recovery to absorb both. This range is built around that.

The growth equation

Training, protein and creatine.

Training tells the muscle to grow. Protein, leucine and creatine decide whether it can. Fall short on any of the three and the session becomes fatigue rather than adaptation.

We formulate for that: a protein with enough leucine to cross the synthesis threshold, creatine at 5g a day and peptides at four capsules a day.

1.6-2.2g
Protein per kg
Per day, spread across four or five meals.
5g
Creatine daily
No loading phase needed; consistency beats timing.
2.5g
Leucine threshold
Per serving, to maximally trigger synthesis.
48h
Elevated synthesis
After a hard session, if you keep protein up.
The essentials

Protein and creatine first.

In priority order. The first two do most of the work; the rest are refinements once those are consistent.

Muscle science

The science of growth.

Three pathways, each with a product behind it. None of it works without the training.

Protein synthesis
01 · Synthesis
Protein synthesis

Growth happens when synthesis outpaces breakdown. Protein contributes to the growth and maintenance of muscle mass.

✓22–23g protein per serving
✓Over 5g BCAAs
Daily creatine
02 · Saturation
Daily creatine

Creatine increases physical performance in successive bursts of short-term, high intensity exercise, which is what heavy sets are.

✓5g creatine monohydrate

Recovery
03 · Repair
Recovery

Muscle is built between sessions. Aim for protein before bed and a consistent sleep routine.

✓Magnesium bisglycinate
The protocol

The training day.

Total daily protein matters more than timing, but these four moments are where the difference shows up over a block.

01 · Morning AM
Prime

Creatine with breakfast, alongside your first protein feed. Taking it at the same time each day makes it easier to remember.

Creatine Monohydrate
02 · Pre-training Pre
Activate

Caffeine 20 to 30 minutes out if you train early or heavy. Hydrate before you start rather than catching up mid-session.

Hydration + Energy
03 · Post-training Post
Build

22–23g of whey within a couple of hours of finishing. The window is wide, but a regular habit keeps daily protein on target.

Whey Protein
04 · Daily PM
Peptides

PeptiStrong® and DL-185® once a day. Neither is a pre-workout.

In plain terms

The muscle-building range

Building muscle takes training, enough protein and recovery. The range here covers the nutrition side: whey with a full amino acid profile, 5g of creatine monohydrate and peptide products at four capsules a day.

Whether you're in a hypertrophy block, adding lean mass alongside strength work, or simply trying to hold muscle through a busy period, these are the products, at the doses on the label, made in the UK.

Before you buy

Questions, answered.

Between 1.6 and 2.2g per kilo of bodyweight a day, spread across four or five feeds of at least 25-30g. Higher intakes show no further benefit for most people.

No. 5g a day reaches saturation in three to four weeks without the stomach upset that a loading phase can bring. Consistency matters more than the start.

Protein, if your daily intake is short. Creatine, if you already hit your protein target from food, it is the cheapest performance gain available.

Less than the internet suggests. Get the daily total right first, then aim for protein within a couple of hours of training and before bed.
