Myprotein

Myprotein is a British online sports nutrition brand founded in 2004 and owned by THG. Its Australian store at au.myprotein.com is run by THG Nutrition Limited, and sells whey, clear, casein and vegan protein, weight gainers, creatine, pre-workout, bars and snacks, and vitamins, alongside MP men's and women's activewear and training accessories. Click through from the ShopBack Myprotein merchant page before you order to earn cashback at the current published rate.

Myprotein Australia runs a referral scheme that credits you $10 for each friend who places a first order of $70 or more. The footer also lists a Loyalty & Rewards page, student discounts and essential worker discounts, and new customers are offered an extra 10% off plus a free shaker through the newsletter. Referral credit and discount codes count as Myprotein promotions, and ShopBack's Myprotein exclusions cover vouchers or codes not featured on its platform, so check the ShopBack Myprotein page terms before combining them with a cashback click-through.

Myprotein runs near-continuous sitewide offers that apply automatically at the basket; as of early October 2026 the Australian site is advertising 35% off almost everything plus an app-exclusive extra 5% off. Deeper stacked offers tend to land around Click Frenzy in November, Black Friday on 27 November 2026, Cyber Monday on 30 November 2026, Boxing Day on 26 December and the New Year fitness period in January. Myprotein also extends its returns window for purchases from 1 November to 31 December until 30 January. ShopBack cashback applies in any window at the rate shown on the ShopBack Myprotein page.

Standard delivery starts at $9.95 and is free on orders over $150, with estimated times of 5 to 8 working days to NSW and Victoria, 6 to 8 to South Australia and the ACT, 7 to 10 to Queensland, 8 to 11 to Western Australia, 5 to 9 to Tasmania and 10 to 15 to the Northern Territory. Express delivery is a $14.99 flat rate with 1 working day to Melbourne, Sydney, Adelaide and Brisbane and 1 to 4 working days elsewhere. ShopBack cashback is calculated on the amount you pay excluding delivery, so the $150 threshold does not change your cashback.

You have 30 days from receiving an item to start a return through the self-serve option in My Account. Nutrition products and bottles must be unopened and unused with seals intact, and clothing must be unworn, unwashed and tagged; underwear, swimwear and socks cannot be returned. Myprotein does not offer exchanges, so you place a new order and return the original for a refund. MP apparel bought from retail partners goes back to that retailer. Any refunded Myprotein order has its ShopBack cashback voided.

Myprotein sells its own-brand range direct, but delivery from its Victorian warehouse takes 5 to 8 working days to the east coast on standard shipping and longer to WA and the NT. A local supplement store or supermarket wins on same-day availability and on multi-brand choice, while Myprotein wins on bulk formats such as the twin-pack Impact Whey and on bundles. For ShopBack, Myprotein is its own merchant page: cashback tracks only on orders completed on au.myprotein.com after clicking through from the ShopBack Myprotein page, at the current published rate.

Both are Myprotein's core whey powders and both appear on the Australian best-sellers page. At the time of writing Impact Whey Protein lists at $49.99 and Impact Whey Isolate at $67.99 per kilogram pack, so the Isolate carries a premium of roughly $18 per kilogram before the basket discount. Check each product page for protein per serve. Whichever you pick, click through from the ShopBack Myprotein page first so the order earns cashback at the current published rate.

Treat them carefully. Myprotein's headline sitewide discount applies automatically at the basket with no code, so it sits alongside a ShopBack click-through. Codes are different: ShopBack's Myprotein terms exclude purchases made with vouchers or promo codes not featured on its platform, which covers the new-customer code, referral credit and third-party codes. If you enter an unlisted code at checkout, the cashback can be declined, so weigh the code against the cashback before you apply it.

Empty your Myprotein basket and close the Myprotein app if you use it, then click through fresh from the ShopBack Myprotein merchant page to au.myprotein.com. Add your protein or MP clothing and complete checkout in the same browser session. Stick to codes featured on ShopBack. Cashback is calculated on the amount you pay excluding fees, taxes and delivery, at the current published rate on the ShopBack Myprotein page. ShopBack lists Myprotein purchases as tracked within 2 days and confirmed within 75 days; if nothing shows as pending, lodge a missing cashback claim with your order number.

Yes. ShopBack's Myprotein terms state that rejected, cancelled, refunded, exchanged or returned purchases are not eligible for cashback. If you return an unopened Myprotein order within the 30-day window and receive a refund, the cashback on that order is voided, and returning part of an order voids the matching portion. Because Myprotein does not offer exchanges, a replacement placed as a new order after a fresh click-through from the ShopBack Myprotein page earns its own cashback on the normal timeline.
