Creatine & Pre-Workout FAQ
Is it safe to buy supplements online in the UK?
Yes — as long as you buy from a UK-registered retailer that stocks batch-tested products with clear ingredient labelling, like SupplementSource. Always check for a full ingredients list and avoid sellers who won’t disclose exact dosages.
How long does UK delivery take?
Orders placed before 2pm Monday to Friday are dispatched the same day and typically arrive within 1-2 working days via tracked courier. Delivery is free on orders over £45.
What’s the difference between creatine and pre-workout?
Creatine monohydrate is taken daily to support strength and muscle power over time, while pre-workout is taken 20-30 minutes before training to boost focus and energy for that session. Many customers use both together.
Do you offer a stim-free pre-workout option?
Yes, our Pre-Workout Zero Stim formula delivers the same pump and focus ingredients without caffeine, ideal for evening training sessions or anyone sensitive to stimulants.
