Myprotein Coupon Codes in September 2026

New subscribers get a 5% off code for their first order. The email usually hits your inbox within a few minutes, but it can take a little longer on some days. It's a small discount, so save this one for when you don't already have a better code lined up.

The real perk of subscribing kicks in after the welcome email. Myprotein sends out sale alerts whenever a sitewide promo goes live, and those usually fall somewhere between 35% and 60% off. The biggest markdowns show up during Impact Week, Black Friday, and Cyber Week. That's how most regular shoppers end up catching the year's best deals without having to keep checking the site.

Subscribe & Save takes up to 50% off select Myprotein staples. Right now, the program covers two best-selling protein powders, with more expected to roll out. You pick how often you want deliveries, every recurring order ships free, and you can pause, cancel, or switch flavors anytime through your account.

Here's the fine print most subscribers miss. Special offers don't stack on top of a Subscribe & Save discount unless they relate to a spend threshold. That means during a big sitewide sale of 50% to 70%, your subscription rate stays the same.

The good news is the workaround is built into the program. You can delay an upcoming order by up to two months total, as long as you give at least five days' notice before billing. Push the next shipment back, place a one-time order at the sale price, and let your subscription pick back up on the new date.

This works best if you reorder the same supplement every one to two months. And thanks to the delay option, you don't have to choose between subscription savings and seasonal sales.

You and your friend each get $20 in Myprotein credit when they spend $40 or more on their first order. The credit shows up within 24 hours of their order shipping. You'll find your referral link in your account under Refer a Friend.

A few details the program page doesn't make clear:

• Credit expires in 90 days from the day it lands in your account. Plan your next order within that window, or you'll lose the $20.

• Sale and subscription items don't count. Your friend's $40 first order needs to be on full-price products.

• You can't stack a promo code. Adding a sitewide code to the same order will likely void the referral, since U.S. terms don't allow it.

• Cancellations cancel your credit, too. If your friend cancels within three days of their order shipping, you won't get the credit.

• Codes are region-locked. UK codes like ANSAB-RX won't work on us.myprotein.com, so always get your own code from your U.S. account.

This works best when you reorder often enough to use the $20 within 90 days. It's less useful when your friend was already planning to buy during a big sitewide sale. The promo code will likely save them more, and the brand's terms don't let you stack both.

The discount code box on us.myprotein.com is labeled "Got a discount code? Enter it here," with a "Use Code" button just below. Where you find it depends on the device you're using.

Desktop or mobile browser

1. Add items to your basket and click the basket icon.

2. Scroll past the items list to find the "Got a discount code?" box. On mobile, you may need to tap the prompt first to open the field.

3. Paste the code exactly as written, since codes are case-sensitive. Click Use Code, and your total will update before payment.

Myprotein app (iOS and Android)

1. Tap the basket icon (the fourth one in the bottom menu), then tap Checkout.

2. The app's extra 10% off applies on its own once you're logged in, so no code is needed.

3. Paste any other sitewide code in the discount field on the same screen.
