Smooth and not clumpy ### ⭐⭐⭐⭐⭐ Great tasting protein powder that keeps me full! *by G***L on August 2, 2025* The media could not be loaded. We love this protein powder. It tastes great and doesn’t have a gross protein flavor or texture. It comes with a scoop and we usually use about one for our shakes and it is plenty. It also keeps me full for longer than other things I have tried! We will be buying more! ### ⭐⭐⭐⭐⭐ Tasty protein powder *by K***E on June 14, 2025* Love the taste of this. I mix it in my Greek yogurt. Love how much protein is on a serving. ## Frequently Bought Together - GNC AMP Sustained Protein Blend | Targeted Muscle Building and Exercise Formula | 4 Protein Sources with Rapid & Sustained Release | Gluten Free | Fruity Crisps | 28 Servings - Nutricost Creatine Monohydrate Micronized Powder 500G, 5000mg Per Serv (5g) - 100 Servings, 17.9 Oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/57658021-amp-sustained-protein-blend-cinnamon-toast-28-servings](https://www.desertcart.pt/products/57658021-amp-sustained-protein-blend-cinnamon-toast-28-servings) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
