Overview
We keep The Bulk Protein Company SERIOUS GAINZ - Whey Protein Powder on our protein powder shelf alongside 44 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: SERIOUS GAINZ by The Bulk Protein Company delivers approximately 460 calories, 27g protein and 74g carbs per serving, helping support a consistent calorie surplus. Each serving provides a balanced blend of protein and carbohydrates to replenish energy after training and support lean muscle growth. The combination of soy protein, whey isolate. That is the maker talking, not us, so read it as a claim rather than a finding. It holds 4.0 out of 5 on Amazon from 1,200 ratings. Where that leaves it next to the rest of the shelf is set out below.

How it compares on the protein powder shelf
We track 45 rated protein powder products, and the middle of that pack scores 4.4 out of 5. This one is on 4.0. That lands in the bottom quarter. Nothing alarming on its own, though at this money you can find better-rated neighbours, so there should be a particular reason for choosing it.
That score rests on 1,200 ratings. The median for this shelf is 474. That's a solid enough base to read the score, though not enough to settle it.
Price-wise it falls in the middle third of a shelf that stretches £14.64 to £170, with £46.40 in the middle. That's the middle of the shelf, which is usually the least regretted place to buy from.

Key features, as the manufacturer lists them
Taken from the product listing via Amazon's product API. These are the seller's claims, not our test results.
HIGH-CALORIE MASS GAIN FORMULA WITH ~27G PROTEIN PER SERVING – SERIOUS GAINZ by The Bulk Protein Company delivers approximately 460 calories, 27g protein and 74g carbs per serving, helping support a consistent calorie surplus. Designed for hardgainers and anyone looking to increase size and strength, it supports muscle recovery, training performance and steady weight gain when combined with a structured nutrition plan.
SUPPORTS MUSCLE GROWTH & POST-WORKOUT RECOVERY – Each serving provides a balanced blend of protein and carbohydrates to replenish energy after training and support lean muscle growth. The combination of soy protein, whey isolate, casein and oat flour delivers both fast and sustained amino acid release, helping refuel muscles, restore glycogen levels, maintain a high daily protein intake and support performance between sessions.
MIXES BEST WITH MILK FOR A SMOOTHER, MORE ENJOYABLE SHAKE – As a bulking protein powder, SERIOUS GAINZ can be prepared with water or milk, though many users prefer milk for a smoother, richer and more consistent texture. Adding liquid first, shaking thoroughly or using a blender helps reduce clumps and creates a creamier shake that’s easier to drink during heavy bulking phases. This preparation method makes each serving more enjoyable and supports daily consistency as calorie needs increase.
SMOOTH, SWEET FLAVOUR EXPERIENCE YOU CAN ENJOY DAILY – This whey protein powder delivers a rich, dessert-style taste that makes each protein shake enjoyable as part of your daily bulking routine. Available in popular flavours such as Chocolate, Cookies & Cream, Vanilla, Strawberry and Banana, it offers options suited to both classic and dessert-style preferences. Whether you mix it with water or milk, or blend it into oats and smoothies, the flavour stays satisfying across long bulking phases.
FILLING FORMULA DESIGNED TO HELP MAINTAIN A DAILY CALORIE SURPLUS – This mass gainer delivers a dense, satisfying shake that helps men and women stay on track with daily calorie targets during bulking phases. Its naturally filling consistency supports a sustained surplus, while starting with smaller servings, adding more liquid or spacing intake can help maintain comfortable, consistent nutrition throughout the day.
