Rule 1 (R1) built its name on clean, high-protein formulas, and the range at Fuel Supplements centres on the R1 Isolate protein in 2lb and 5lb sizes, the slow-digesting R1 Casein, and the Pre Lift pre-workout. If you want a lean protein with straightforward macros — or a nighttime casein to round out your intake — Rule 1 is a dependable pick.
Rule 1 FAQ & Buying Guide
What are Rule 1's most popular products at Fuel Supplements?
The Pre Lift pre-workout and R1 Isolate protein — especially the 5lb tub — lead the collection, with R1 Casein a steady favourite for evening use.
What is Rule 1 known for?
No-nonsense protein: the brand focuses on isolate-first formulas with simple ingredient lists, plus supporting products like casein and pre-workout rather than a sprawling catalogue.
R1 Isolate or R1 Casein — which should I choose?
Isolate digests quickly, making it the go-to around workouts or any time you want fast protein. Casein digests slowly, so it suits before bed or long gaps between meals. Many lifters use isolate by day and casein at night.
Does Fuel Supplements ship Rule 1 across Canada?
Yes. We ship Rule 1 Canada-wide from our BC warehouses, with free shipping on orders over $100 and same-day pickup available in Port Coquitlam.
