You get a tracking link the moment your order ships.

Free EU shipping on orders over €60. Below that, a flat €4.99 shipping fee applies to most EU destinations.

Active subscriptions always ship free, regardless of order value.

As soon as your order leaves our warehouse, we email you a tracking number with a direct link. You can also log into your account → Orders → click the order for live tracking.

If your order hasn't shipped yet, yes — email hello@oxynsupps.com with your order number and the new address. Once it's left the warehouse we can't redirect it.

Carriers sometimes lag on tracking updates by 24–48 hours. If your order is more than 3 business days past the estimated delivery window, email us with your order number — we'll chase the carrier and either locate it or send you a replacement.

Returns accepted within 30 days of delivery, provided the tub is sealed and unopened. Once opened, EU food-safety law prevents us from accepting supplements back — this is standard across the industry for hygiene reasons.

Full refund minus return shipping on returned sealed product.

Email hello@oxynsupps.com with your order number and a photo showing the tub is still sealed. We'll send return instructions and a shipping label within 24 hours.

Once we receive and verify the returned product, we process the refund within 2–3 business days. Your bank may take an additional 5–10 days to display it on your statement.

Email us within 48 hours of delivery with a photo of the damaged tub and packaging. We'll send a replacement at no cost — you don't need to return the damaged one.

Change-of-mind returns: you cover return shipping.

Damaged or wrong items shipped by us: we cover everything.

Yes. No animal products, no whey, no eggs. Our pre-workout and creatine are 100% vegan and certified by the manufacturer.

Yes to both. No gluten, no soy. Manufactured in a GMP-certified facility under strict EU food safety law. The full allergen statement is printed on every tub.

300mg of dual-source caffeine per scoop — caffeine anhydrous + di-caffeine malate. For reference, a strong espresso shot is around 80mg. Don't combine with other caffeinated drinks before training.

Yes — that's the beta-alanine. The technical name is paresthesia. It's harmless, fades after a few weeks of consistent use, and is actually a sign the product is properly dosed (most cheap pre-workouts skip the dose needed to feel it).

No. One scoop in any 24-hour period. The formula is dosed at clinical research levels — doubling up doesn't make it work better, it just increases side-effect risk and pushes caffeine above safe daily limits.

20–30 minutes before training. Mix one scoop with 250–300ml of cold water. Energy peaks around minute 40 and stays steady for the next 90 minutes. Don't take it within 6 hours of bedtime.

Yes — they're designed to work together. Take 3–5g of our Pure Monohydrate daily, anytime (timing doesn't matter much for creatine). The Foundation Stack bundle saves you €15 on the pair.

· Under 18 · Pregnant or nursing · Have a heart condition, high blood pressure, or any chronic medical condition · Sensitive to caffeine or stimulants · Taking prescription medication.
