Informed Mass, Strawberries and ...
Pros
- ✓No maltodextrin — oat flour provides complex carbs with a lower glycaemic impact, widely praised by reviewers
- ✓Informed Sport certified, providing reliable banned-substance assurance for competitive athletes
- ✓Added creatine monohydrate (3g) and HMB (1.5g) add meaningful ergogenic value beyond a standard gainer
- ✓Generally well-tolerated, with DigeZyme enzyme blend supporting digestion of the large serving size
Cons
- ✗Mixes poorly in a shaker without a blender — clumping and undissolved particles reported by multiple reviewers
- ✗Thick, heavy texture is polarising; some users found it unpleasant to drink
- ✗Only 20 servings per 3kg bag — serving size (150g) is large and the bag depletes quickly
- ✗Taste described as average to decent across flavours; some find it overly saline or requiring large water volume
Best For

- ✓50g protein per serving aids muscle protein synthesis and recovery

Cons
- ✗Extremely high sugar content (12g per serving) and 250g carbs may cause energy crashes or GI distress in sensitive individuals
- ✗Not third-party tested or certified (no NSF, Informed-Sport, or banned substance screening listed)
- ✗Contains common allergens (milk, soy, wheat, gluten) limiting accessibility
- ✗Very high serving size (336g per scoop) makes convenient dosing impractical; typically mixed with large volumes of liquid

What does the data say about Informed Mass, Strawbe... vs Serious Mass Cookies &...?
Informed Mass and Serious Mass serve the same purpose — packing calories and protein for hard gainers — but they take different approaches. Informed Mass delivers 45g protein and 550+ calories per serving using oat flour as its carb source, sidestepping the maltodextrin found in many gainers. Each serving also includes 3g creatine monohydrate and 1.5g HMB, which add real ergogenic value. Serious Mass goes heavier on the calories: 1,250 per serving with 50g protein, making it a faster route to a surplus. The trade-off? Serious Mass contains 250g carbs per serving and 12g sugar, whereas Informed Mass is built on slower-digesting oats.
Pick Informed Mass (£45) if you want a cleaner ingredient profile and don't mind thick, hard-to-mix powder without a blender. It scores 77/100 overall, with ingredient quality at 83/100. Pick Serious Mass (£40) if taste and ease matter more — reviewers praised its mixability and flavour. It scores 70/100 overall but edges ahead on both effectiveness (80 vs 72) and value (80 vs 76).
The practical difference: Serious Mass mixes easily in a shaker, whereas Informed Mass will clump without a blender. If you're sensitive to sugar or carb crashes, Informed Mass suits you better. Budget-conscious? Serious Mass saves five quid.
Bulk's Informed Mass is a premium lean mass gainer built around a tri-protein blend (whey concentrate, isolate, and casein) delivering 45g protein and 550+ kcal per serving from oat flour rather than maltodextrin — a distinction repeatedly praised by reviewers.
