In a world where protein powder is practically a food group for lifters, it's easy to assume every scoop is fueling your gains. But behind the flashy labels and massive "30g PROTEIN" stamps, there's a less talked about trick some companies have used to cut corners: amino spiking.
Also called nitrogen spiking, this is the practice of adding cheap amino acids like glycine, taurine, or even creatine to protein powders to artificially inflate the protein content listed on the label. How? Because protein is measured based on its nitrogen content, and these amino acids contain nitrogen too. The result: the lab test reads "high protein," but your muscles might not agree.
As explained in MyProtein's article on amino spiking, these added aminos aren't necessarily harmful—but they're not delivering the complete protein profile your body needs for muscle growth. You might still be getting 30g of something, but if it's padded with non-essential amino acids that don't stimulate muscle protein synthesis, then you're overpaying for underperformance.
Andy Morgan of RippedBody goes even further, warning that this isn't just some minor industry loophole. It's a full-on scam. He highlights how some supplement companies use amino spiking to save money on raw ingredients, while passing the cost onto unsuspecting consumers. And unless the label clearly shows an amino acid breakdown (most don't), there's almost no way to tell how much real, complete protein you're getting.
How to Protect Yourself
Here are a few quick tips:
- Check for transparency. Legit brands often show a full amino acid profile and are third-party tested.
- Be skeptical of unusually cheap protein powders. If it sounds too good to be true, it probably is.
- Watch for added aminos. If glycine, taurine, or similar ingredients show up early on the label, that's a red flag.
Not all protein powders are created equal. And in a market full of hype, it pays to be an informed buyer.
