Description
What's inside & why it works
Not sure you'll like Rebuild? This is the cheaper way to find out before you buy a tub.
You get six single-serve sachets - two each of Dutch Chocolate, Salted Caramel and Vanilla - and a Tuff Supps 400ml shaker to mix them in. Two of each flavour means you can have one with water and one with milk before you pick a favourite.
Every sachet is the same Rebuild that goes in the tub: grass-fed whey with collagen peptides, naturally low lactose and sweetened with organic stevia only. No bloat-causing ingredients.
If you like it, we email you a $25 gift card to put toward your first tub. Shipping on the box is free.
How To Use
Dosage & timing
Tip a sachet into the shaker with 250-300ml of cold water or milk, shake it and drink. One sachet makes one shake.
Getting the best read on each flavour:
Have the first sachet of each flavour with water and the second with milk - that's what the two of each is for
Shake it for 10-15 seconds rather than stirring, it mixes cleaner
Judge the taste cold - protein always tastes sweeter at room temperature
Try one after training and one at breakfast if you're working out when you'd actually use it
Use as part of a balanced diet. Protein needs vary by body size, training and total food intake.

INGREDIENTS
Every ingredient has a place.
No fillers. No shortcuts. Just performance.
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.
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.
FAQs
Frequently asked
questions
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.
Active people generally aim for around 1.2 to 2.2 grams of protein per kilogram of body weight per day, depending on training load and goals. The specific amount varies with your fitness goals, activity level and overall food intake - and it's best spread evenly across the day.
Thick, creamy and naturally sweetened with organic stevia. No artificial aftertaste. Available in Dutch Chocolate and Salted Caramel, with more flavours returning soon. Not sure? Grab a single-serve sample before committing.
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.
