Pre workout supplements can be expensive, but knowing where and when to shop can save you significant money. We track prices across all major UK supplement retailers to help you find the best deals on popular pre workouts throughout the year.

Best UK Retailers for Pre Workout Deals

Amazon UK often has the most competitive day-to-day pricing, especially with Subscribe & Save discounts of 5-15%. For branded products like Ghost Legend and Ryse Godzilla, Amazon frequently undercuts specialist supplement stores. Myprotein runs aggressive sales throughout the year — their Impact Week, Black Friday, and regular flash sales can bring prices down by 40-60%. If you’re buying Myprotein’s own THE Pre Workout, always wait for a sale as the RRP is rarely worth paying.

Bodybuilding Warehouse and Supplement Needs are specialist UK retailers that often have exclusive bundles and loyalty programmes. Bulk Powders (now Bulk.com) also runs frequent promotions on their own-brand pre workouts. For US brands like Transparent Labs or Gorilla Mode, buying direct from their websites with occasional discount codes often beats third-party UK sellers.

When to Buy: Key Sale Periods

The best times to stock up on pre workout in the UK are January (New Year fitness sales with 30-50% off across most retailers), Easter weekend (spring sales often include supplement deals), Amazon Prime Day in July (excellent for mainstream brands), Black Friday and Cyber Monday in November (the biggest discounts of the year, often 50-70% off), and Boxing Day sales extending into early January.

Price Comparison Tips

Always compare price per serving rather than price per tub, as serving sizes vary significantly between brands. A £45 pre workout with 40 servings (£1.12/serving) is actually better value than a £30 product with 20 servings (£1.50/serving). Also check the dosing — some brands recommend two scoops for a full dose, effectively halving the number of servings.

Subscription Savings

If you consistently use the same pre workout, subscription services can save you 10-20% per order. Amazon Subscribe & Save, Myprotein’s auto-delivery, and various brand-specific subscription programmes all offer meaningful discounts for regular buyers. Just make sure you actually want the product long-term before committing — cancelling can sometimes be more hassle than it’s worth.
