Myprotein

Shopping Myprotein? Pick your items, then check out through ShopBack before you pay: ShopBack Cashback works like a discount, only easier than a promo code. 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. Bigger offers tend to land around Click Frenzy in November, Black Friday, Cyber Monday, Boxing Day and the New Year fitness period in January. Myprotein also extends its returns window for holiday-period purchases. During these sales, the sale price is what you pay at checkout. Going through ShopBack before you pay is an essential step, and part of what you spend comes back as Cashback. Check the rate shown on ShopBack's Myprotein page before you buy.

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.

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.

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.

Go through ShopBack before you pay and the Cashback tracks to your ShopBack account. Start from the ShopBack Myprotein page and finish the order on au.myprotein.com. The current Cashback is shown on the Myprotein page on ShopBack.

Myprotein accepts returns of unopened orders within 30 days. Because Myprotein does not offer exchanges, a replacement is placed as a new order: go through ShopBack before you pay and that order gets its own Cashback on the normal timeline.
