Myprotein Discount Code: Why There's Always One — and How to Keep 15% Cashback on Top (Instead of 1%)

Last verified: 8 September 2026 · By The Cashback Chap

Nobody should ever pay Myprotein's list price — the brand's pricing is built around a permanent rotating code (25% off £40+, 15% sitewide, bigger during events), printed on its own voucher page. So the real question isn't "is there a code" but "how do I use one without losing cashback?" — because TopCashback's Myprotein listing pays 15% on clothing and electrolytes, 12% on vitamins and 4% on protein, and an unapproved code cuts all of that to 1%. The fix is simple once you know it.

Disclosure: cashback links here are my referral links — free for you (you get a £10 bonus). I haven't bought from Myprotein through cashback; codes and rates are as listed on the day.

Myprotein codes — where they live

Myprotein's official voucher page	15–25% sitewide; 25% off £40+ common	The code changes weekly; also shown in the site banner

Cashback at Myprotein — by category

Category	TopCashback

The rule that saves the most: use the *approved* code

Myprotein codes are so universal that TopCashback lists them on the merchant page. An approved code keeps your category rate; the identical-looking code copied from a coupon site is "unapproved" and drops you to 1%. Same discount, different cashback.

• £60 protein, 25% approved code: pay £45 → 4% cashback £1.80 → net £43.20. Unapproved code: 45p.
• £50 clothing, 25% approved code: pay £37.50 → 15% cashback £5.63 → net £31.88. Unapproved: 38p.
• £30 electrolytes, 25% approved code: pay £22.50 → 15% → £3.38 back.

Clothing and electrolytes are where cashback genuinely matters; on protein it's a small bonus, and the code does the heavy lifting.

The stack

1. Open TopCashback's Myprotein listing and note the approved code.
2. Click through TopCashback to Myprotein (web, not app).
3. Fill the basket — bigger bags cut the per-kilo price more than any code.
4. Apply the approved code only. No stacking a second code from elsewhere.
5. Pay by card, same session; cashback usually tracks within 7 days.
