About MyProtein Protein Prices
Is MyProtein the cheapest whey?
During sales (which run often), MyProtein Impact Whey is frequently the cheapest verified whey per gram in our catalog. Outside of sales, Amazon or iHerb may be cheaper.
How long does MyProtein shipping take?
US delivery typically takes 4–7 days from their UK warehouse. Free shipping on $80+. Expect slightly longer during sale periods due to volume.
Are MyProtein sales legit?
Yes — MyProtein runs genuine discounts of 30–50% off multiple times per month. We track their live prices so the rows above already reflect current sale pricing.
