5g collagen peptides per serve - the daily dose shown to improve skin elasticity in clinical trials.
Individual results vary. Reflects what customers commonly report with daily use alongside training.
Grass-Fed Whey
A blend of whey isolate and concentrate from pasture-raised, grass-fed cows - 27g of protein per serve with the clean hit of WPI and the creamy taste of WPC. Naturally low lactose, so it sits right.
5g Collagen Peptides
Hydrolysed bovine collagen at the daily dose shown to support skin elasticity in clinical trials. It looks after the structure - skin, joints, tendons - and the benefits build over weeks of daily use.
7g BCAAs
Naturally occurring in the whey - no amino spiking, no inflated numbers. Leucine, isoleucine and valine feed muscle repair, so you back up session after session.
Naturally Sweet
Flavoured naturally and sweetened with organic stevia. No artificial sweeteners, no fillers - nothing on the label you can't read.
How To Use
SCOOP
1 scoop, once a day - training days and rest days
SHAKE
250-300ml of cold water or milk - vary it to taste
DRINK
Post-training, breakfast, or whenever protein's the gap
COOK
Or stir it into oats, smoothies and baking for a protein boost

If any of these are you
YOU TRAIN HARD
High-volume phases where the joints take as much of a beating as the muscles.
YOU'RE IN IT FOR THE LONG RUN
Training isn't a phase. You want to recover well, stay strong, and still be turning up in twenty years.
STANDARD WHEY DOESN'T SIT RIGHT
Every tub so far has left you bloated or heavy. Naturally low lactose and minimal ingredients change that.
YOU WANT MORE THAN MUSCLE
Skin, joints and tendons matter as much as the mirror - and collagen works on the parts training stresses most.

The WPI is pure whey isolate - 27.8g protein, less than 1g fat and carbs, 99.9% lactose-free. It's the leanest option. Rebuild combines whey isolate and concentrate with 5g of hydrolysed collagen peptides to support joints, tendons, skin and recovery alongside muscle. Choose WPI for maximum protein with minimum calories. Choose Rebuild if you want muscle and structural support in one serve.
Rebuild contains hydrolysed bovine collagen peptides which support joint, tendon and ligament health over time. It's not a quick fix, but consistent use alongside training helps reinforce the connective tissue that takes a beating during heavy or high-volume sessions. Most customers notice a difference within 4-6 weeks.
Rebuild is naturally low in lactose and made with minimal ingredients - no artificial sweeteners and no fillers, which are common causes of bloating in standard protein powders. It's not as lean as our WPI (which is 99.9% lactose-free), but most customers report no digestive issues.

You can, but most people won't need to. Rebuild already delivers 5g of hydrolysed collagen per serve alongside 27g of whey protein. That's a solid daily dose of collagen for joint and connective tissue support without buying two separate products.
Yes. Rebuild supports lean muscle retention during a calorie deficit while the collagen helps maintain skin elasticity and joint health as body composition changes. The added fullness from the thicker texture also helps with appetite control between meals.
