Sachets & samples

Try a flavour or serving size before you commit to a full tub. This collection gathers every sachet and sample we stock — whey and clear protein, pre-workout, creatine, electrolytes and recovery singles from brands on GymStack.

Single serves are useful when you want to test a flavour, travel light, or keep a spare serving in your bag. Boxes of sachets sit here too, so you can buy a month of singles in one go.

Browse by brand or product type, then add the singles you want. When you find a flavour that works, step up to the matching tub from the same brand. Orders over £75 ship free in the UK.
