Live prices
If you're shopping for ready-to-drink protein shakes at ASN and want to stretch your budget, this comparison shows what's currently available sorted by price. As of May 2026, the most affordable options start at $5 per bottle, with brands like Optimum Nutrition and EHP Labs dominating the entry-level price point. We refresh this data regularly so you're seeing current pricing. When comparing different products, don't just look at the sticker price. Check the cost per gram of protein, which tells you what you're actually paying for the protein content itself. For example, a $5 shake with 25g of protein (2 cents per gram) delivers better value than a $6 shake with only 16g of protein (3.6 cents per gram). This page lists ready-to-drink shakes available at ASN stores and online, ranked from cheapest to most expensive, so you can quickly find options that fit your budget without doing the maths yourself.
Check the price per 25g of protein, not just the bottle price - a $4 shake with 40g protein beats a $3 one with 15g.
How the live ProteinPrice Value Score is calculated
Optimum Nutrition's Amino Energy Sparkling RTD ranks 1st on this list with a strong value score of 9.7 out of 10. At $5 per can from ASN, it's the cheapest ready-to-drink option available. The main trade-off is the 360g size, which is smaller than typical protein shakes. It's a solid pick if you're after convenience and affordability without breaking the bank on larger formats.
EHP Labs OxyShred Energy RTD ranks 2nd on this list at $5 per bottle from ASN. It's technically a thermogenic fat burner rather than a traditional protein shake, so the cents per gram protein metric (193.05) reflects lower protein content than dedicated protein drinks. The 370g size is generous compared to typical RTDs. With a value score of 9.7 out of 10, it's competitively priced if you're after an energy drink with some protein content.
EHP Labs OxyShred Infinity RTD ranks 3rd on this list at $5 per bottle. The value score of 9.7 out of 10 reflects solid pricing for a ready-to-drink option. At 370g per serve, it's a larger format than typical RTDs, which helps justify the cost. Worth noting this is technically a fat burner product rather than a pure protein shake, so check the macros match your goals before buying.
EHP Labs' Oxyshred Lean Protein RTD ranks 5th on this list at $6 per bottle from ASN. The value score of 9 out of 10 reflects decent protein cost efficiency at 3.6 cents per gram. At 460g total weight, these are notably larger than typical RTD shakes, which explains the higher upfront price. The chocolate milkshake flavour is a safe mainstream option for most drinkers.
