You can knock money off a Grenade order without hunting for a rare voucher code, because two standing offers apply to most baskets: new customers get 20% off a first order by joining the Grenade Rewards Academy on a minimum spend of £40, and UK orders over £40 ship free by express delivery.

What Grenade actually sells

The range is built around high protein snacking. The bars carry over 20g of protein and under 2g of sugar each, and run to roughly 15 flavours across the standard and Soft Core lines, including OREO, Salted Caramel, White Chocolate Salted Peanut and Cookie Dough. Alongside them sit bottled protein shakes, protein spreads and supplements such as creatine and thermogenic capsules.

Getting the most out of one order

Because the free delivery and the welcome discount both sit at £40, a single larger order beats two small ones. Multipacks and twelve bar boxes are the usual way to cross that line, and pushing past £60 adds the free gift on top. If you are buying for training rather than snacking, the capsules and powders count towards the same basket total.

For everyday supplement staples it is worth comparing prices with Raw Powders, and if you need kit rather than fuel, Your Fitness Hub covers the equipment side.

FAQ

Is there a Grenade discount code for a first order?

Yes. Joining the Grenade Rewards Academy gives 20% off a first order with a minimum spend of £40. It applies to first time customers only.

When does Grenade deliver for free?

Free express delivery applies to UK orders over £40. Below that a delivery charge is added at checkout.

Does Grenade do a student discount?

Grenade does not advertise a dedicated student scheme on its own site. The 20% welcome offer through the Rewards Academy is open to students and usually beats a standard student rate.

Is there a Grenade NHS discount?

No NHS or Blue Light offer is listed on the Grenade site. Staff can still use the welcome discount and the £40 free delivery threshold.

How much protein is in a Grenade bar?

Each bar carries over 20g of protein and less than 2g of sugar. That holds across the standard and Soft Core ranges.

What is the difference between the standard bars and Soft Core?

Soft Core uses a softer centre and a different texture while keeping the same protein target. Flavour lists overlap but are not identical.

What comes in the welcome pack?

First orders include a free welcome pack. The contents change with the current promotion, so check the offer note shown in your basket.

Why is my voucher code not working?

Check the minimum spend first, because most Grenade codes need a £40 basket. Welcome codes are also restricted to first time customers and will not apply on a repeat account.
