Quick answers
Is this right for you?
Who is it for?
The Bulk Protein Company Serious Shredz Diet Protein Powder is designed for anyone who wants a quick, calorie-controlled shake to replace a meal, with protein, carbohydrate, fibre and added vitamins and minerals rather than protein alone.
What can you expect?
A shake built to stand in for a meal. Meal replacements carry less protein per 100g than a standard protein powder, because the rest of each serving is carbohydrate, fibre and fats, with vitamins and minerals added. Check the calories per serving against the meal you are replacing. With 64.6g of protein per 100g (around 19g per 30g serving), The Bulk Protein Company Serious Shredz Diet Protein Powder sits in a solid mid-range for a meal replacement product.

Every price on WheyWise is read from the retailer’s own page and re-checked daily and sorted by cost per 100g, so you can see both the cheapest option and how current it is.
