Choose your flavours

Where a product is available in multiple flavours, the winner can choose their preferred available flavour when the prize is ordered.

So you won’t necessarily receive the Blackcurrant, Berry, Orange or Vanilla options shown in our example imagery – those are simply the variants used when we priced the bundle.

All flavour choices remain subject to current Science in Sport stock and availability.
