Get 45% off with a Bulk referral code
If you're stocking up on protein powder, creatine or snack bars, a Bulk referral code is the easiest way to knock a chunk off your first order. This guide walks through exactly how the Bulk referral code works, what you and your mate both get, and how to get the most out of it before you spend a penny.
What Bulk actually is
Bulk (formerly Bulk Powders) is one of the biggest sports nutrition brands in Europe, based in Colchester, Essex. It sells whey protein, vegan protein, creatine, pre-workout, mass gainers, vitamins, and a growing range of snacks like protein flapjacks, cookies and crisps. The company has been trading since 2004 and ships from its own UK warehouse, which means orders tend to move quickly and the catalogue runs into the hundreds of products.
Bulk's pitch is straightforward: gym-quality supplements at prices that don't require a second mortgage, sold in big-value tubs (1kg, 2.5kg and 4kg bags of protein are the norm rather than the exception). It also owns a physical presence with a flagship store and gym in Colchester, and its products are stocked in some UK supermarkets and Holland & Barrett stores. Pricing sits in the mid-market range: a 1kg tub of whey protein typically costs somewhere between £15 and £25 depending on flavour and any live promotions, and the brand runs frequent sales, particularly around Black Friday and New Year.
Quality-wise, Bulk has built a decent reputation among gym-goers for consistent taste and mixability, and it publishes batch testing information for some of its ranges. It isn't positioned as a premium boutique brand: it's a volume player competing hard on price, which is exactly why a Bulk referral code matters so much here. Every percentage point off adds up when you're buying in bulk (pun intended).
How the Bulk referral code works
The scheme runs on Mention Me, a referral platform used by dozens of UK retailers, so the mechanics will feel familiar if you've used a referral link for another brand before. Here's the step-by-step:
- An existing Bulk customer generates their personal referral link through Bulk's official refer-a-friend page or via an email/SMS Mention Me sends after a purchase.
- They share that link with a friend, family member or on social media.
- The friend clicks the link, which opens a page confirming the current new-customer discount, and either automatically applies it or shows a code to pop into the promo box at checkout.
- The friend places a qualifying order (there's usually a minimum spend involved, so check the pop-up before you commit to a cart).
Because this all runs through Mention Me, using the Bulk referral code isn't a case of typing random letters into a discount box. It's tied to a specific tracked link, so make sure you actually click through it rather than just quoting a code from memory, as some Mention Me integrations only fire the discount when the link's cookie is present.
What you and your friend get
The current headline reward advertised through this referral route is 45% off your order. That's a strong discount by supplement industry standards, and it typically applies to a new customer's first purchase rather than being available indefinitely. Bulk (and Mention Me generally) can and do change the exact percentage from time to time, running smaller or larger promotions depending on season and stock levels, so always check the number shown on the referral landing page before you check out, as that's the live, binding offer rather than anything printed elsewhere.
It isn't typically cash, so it's best thought of as a way to fund your next protein restock rather than a payout to your bank account.
Eligibility, timing and the small print
A few practical points worth knowing before you rely on a Bulk referral code:
- The discount is aimed at new customers. If you've ordered from Bulk before under the same name, email or account, the referral discount generally won't apply.
- There's often a minimum order value attached to unlock the full discount, so check the terms shown when the code loads.
- Referral rewards are usually credited after a qualifying window has passed (to account for returns or cancellations), so don't expect an instant credit the moment your friend hits "buy."
- Bulk and Mention Me can cap the number of referrals that earn a reward in a given period, or exclude certain product lines (like heavily discounted clearance stock) from qualifying.
- Codes and links expire or get refreshed periodically, so a link shared months ago may no longer carry the same percentage.
As with most Mention Me schemes, Bulk's referral terms sit in a dedicated help article on its support site, so it's worth a quick check there if your discount doesn't apply as expected.
Using Bulk well once you're in
Once your discounted order lands, a few things are worth knowing to get real value out of the brand rather than just the one-off saving:
- Buy the bigger bag. Bulk's protein tends to get noticeably cheaper per serving as tub size increases, so a 2.5kg or 4kg bag is usually far better value than repeatedly buying 1kg tubs, assuming you'll get through it before the best-before date.
- Watch for sitewide sales. Bulk runs regular promotions (Black Friday, January "new year" pushes, and periodic flash sales), and these can sometimes beat a referral discount on certain lines, so it's worth comparing before you buy.
- Sample flavours first. Bulk sells small sample sachets of most protein flavours, which is a cheap way to avoid committing to a 4kg tub of a flavour you end up disliking.
- Check the clean label range. Bulk's "Pure" and unflavoured lines are aimed at people who want minimal additives, while its flavoured mainstream range leans sweeter, so pick based on your taste preference rather than assuming one range fits all.
- Subscribe and save if you're a regular. Bulk offers subscription pricing on some products for people who order the same items repeatedly, which can be worth stacking with occasional referral or sale discounts.
Honest pros and cons
Pros:
- Large discount available through the referral route compared with many everyday voucher codes.
- Genuinely wide product range covering protein, snacks, vitamins and pre-workout in one basket.
- UK-based warehouse means fast, predictable delivery for most postcodes.
- Frequent promotions mean there's rarely a bad time to buy if you shop around the calendar.
Cons:
- The referral discount is for new customers only, so it's not repeatable on every order.
- Reward is a credit or code rather than cash, so it only has value if you plan to shop with Bulk again.
- Minimum spend thresholds can mean the discount pushes you into buying more than you originally intended.
- As with any budget supplement brand, some flavours and textures split opinion, so first-timers should expect a bit of trial and error.
Tips to make the reward land
Always click through the actual referral link rather than typing a code from memory into an unrelated box, since Mention Me offers are often link-tracked. Check the minimum spend and expiry date shown on the landing page before adding items to your basket, as that's the version of the offer that will actually be honoured. If a friend's order doesn't seem to register, hold onto your order confirmation and get in touch with Bulk's customer service team, who can usually manually check Mention Me's tracking on request. And don't stack multiple referral or discount codes hoping they'll combine, most retailers, Bulk included, will only apply one promotional code per order.
Alternatives worth comparing
Bulk isn't the only budget-friendly supplement option in the UK. MyProtein is the most obvious comparison, another mass-market brand with frequent deep discount codes and a huge range, though delivery times and stock consistency get mixed feedback. Protein Works is a smaller UK competitor known for unusual flavours and regular flash sales. For a slightly more premium feel, Applied Nutrition and PhD Nutrition are widely stocked in UK supermarkets and gyms, generally at a higher price point than Bulk. If you're specifically after clean-label, minimal-ingredient products, brands like Form Nutrition are worth a look, albeit at a higher price than Bulk's budget tubs.
Verdict
It's worth using if you're already planning to buy protein or supplements and happen to have a friend who shops with Bulk, or vice versa. Just go in with realistic expectations about minimum spend, new-customer restrictions, and the fact that your reward will land as store credit rather than cash.
