SiS Rego Whey Protein 1.35KG

Science In Sport REGO Whey Protein – 1.35kg

A clean, recovery-focused whey protein built for serious athletes, lifters, and active adults who train short, high-intensity sessions and need quality protein to drive muscle repair and growth without unnecessary added carbs. Ideal as a post-training recovery shake for gym workouts, sprint sessions, and resistance training where the priority is protein, not bulk calories.

What makes REGO Whey worth choosing over the average tub comes down to formulation purpose. Each 30g serving delivers 22g of high-quality whey protein with a complete profile of all nine essential amino acids — including the leucine, isoleucine, and valine that drive muscle protein synthesis after training. Unlike post-workout recovery powders that load up on carbohydrates (which matter for endurance athletes but not for shorter sessions), this is deliberately built lean for trainees whose primary need is protein for muscle rebuild and repair, not glycogen replenishment. It also mixes easily with cold water — no clumping, no needing a milk carrier — which matters when you're trying to drink it fast post-session.

Science In Sport is a UK-based brand publicly listed on the London Stock Exchange (AIM: SIS) and manufactured to GMP standards. The brand's broader range is widely Informed-Sport certified for elite athletes, with batch-level testing across its performance line — making REGO Whey a credible whey protein for athletes operating in tested pools. For competing athletes in Sri Lanka, always check the individual batch certification on the SiS website; for everyone else, the brand's pedigree as official supplier to multiple WorldTour cycling teams and Olympic federations underpins the formulation quality.

• 22g of high-quality whey protein per 30g scoop — clean macros built for recovery, not calorie loading

• 45 servings per 1.35kg tub — strong value at the whey protein price in Sri Lanka category for a UK performance brand

• Used by professional cycling teams and Olympic athletes — credible whey protein for athletes in the recovery space

Pair it with a daily multivitamin or recovery supplement from our vitamins and supplements range to round out a complete training stack.

Add one scoop (30g) to 300ml of cold water in a shaker, seal, and shake for 10–15 seconds. Best consumed within 30–60 minutes post-exercise to take advantage of the post-training recovery window. Can also be used between meals to hit your daily protein target. Store with the lid sealed in a cool, dry place away from direct sunlight..
